The presence of pumps in a flood defence scheme will benefit those involved and the success of the scheme. Many consider flood defences to be impenetrable walls blocking water from entering homes and properties. However, the reality is that few possess permanent flood doors and barriers and even the ones that do, can tell you they are not 100% effective and will always have a point where the water can defeat and overtop them. Fixtures such as these are typically pre-installed in anticipation of future flooding, often at high costs.
Pumps offer an extra line of defence say, if the water became too high and breached a flood door. They can pump water away quickly and to a low level, sometimes as low as 1mm. There are also a range of pumps available on the market, with some being able to pump more than 1000L a minute. Pumps are also available in automatic and manual so, for example, if a person’s basement regularly flooded, they could install an automatic pump which would turn itself on when the water reached a certain level and then turn itself off once it had reduced the water to a particular level. Flooding like this typically occurs via groundwater flooding.
Used in conjunction with temporary barriers, pumps offer an inexpensive and effective line of defence against flood waters. Temporary barriers don’t require prior installation like flood doors, can be deployed in a matter of minutes and are usually significantly cheaper. Freestanding temporary barriers, such as the Water-Gate, will always allow a small amount of water to seep through. This is when a pump is needed, as it can stop any seepage from pooling and be pumped away quickly. A defence scheme like this can be stored away and erected in a matter of minutes when there is a threat of flooding. It is ideal for people who are concerned by the threat of flooding, who want to have defences available if it were ever to happen but don’t want to alter the aesthetics of their property.
For the cost, which can be as little as £60, pumps provide an extra, versatile line of defence which will give any flood defence scheme a way to moving water from a property or area at risk to an area where the water can dissipate or be stored. They also benefit the effectiveness of other defences in place, elevating the overall scheme. From domestic to industrial use, there is a vast range on the market designed for every scenario, meaning there will be one to suit your situation.
Automatic Water Pumps and the Different Switches
Once turned on at the mains, an automatic water pump will turn itself on or off as the water level rises or falls. Automatic pumps are very useful in projects as they are often only seen twice in their life, once when installed – and eventually when they are removed for replacement. They can be used as part of a passive system, as they are effectively ‘fit and forget’ as the pump will come on when required. This makes them brilliant for use in basements, or sumps, where the level is not manually monitored.
Automatic Pumps are Available with Different Styles of Float Switches
There are 3 main types of automatic switches available:
- Pendant float switch
- Tube float switch
- Sensor panel
The diagram below compares a manual pump, with two automatic pumps, one with a pendant float switch, and one with a tube float switch.
Pendant Float Switch
Pendant float switch pumps have a paddle like float attached to them. These work on pretty much the same premise at the ball cock system in a typical toilet.
The float hangs down at the side of the pump, when the water rises, the float rises along with it. Once the water reaches a certain height the float reaches its ‘on’ position, which then turns the pump on and begins to pump the water away. When the water lowers, the float lowers back down to the ‘off’ position this turns the pump back off again.
These type of pendant floats are not ideal for every situation due to the clear area they need around the pump so that they do not snag or catch on any obstacles stopping them from working. The diagram above shows how this can be an issue in narrow chambers.
This system does not offer exact depths at which the pump will turn on or off.
Tube Float Switch
These pumps are designed for tight spaces, such as sumps or narrow chambers. Examples include the Tsurumi POMA Submersible Automatic Sump Pump (pictured left).
Unlike the pendant float switch that dangles from the pump and sits on the surface of the water, the tube float is exactly that, it is a tube attached to the pump with a small float inside. When the water surrounds and raises around the pump, the ball float inside the tube raises with the water turning the pump on, when the water level falls the float drops along with it turning the pump off.
This prevents the float switch from fouling or becoming stuck on a chamber, as the diagram shows. They also have an on and off level provided, so you know when the pump will be activated.
There are a few pumps available which a sensor panel built on to the side of the pump housing, or in a separate panel. These can be used when the on or off position needs to be much lower, and more accurate than a standard paddle float can provide.
An example is the APP RS32EA Submersible Puddle Pump (pictured right). A fixed panel it is ideal in enclosed spaces and where minimum water levels are required. These can pump the water away to an accurate required depth to the nearest milometer.
These are more expensive than pendant float switches due to the more complex electronics involved.
Automatic pumps are designed to turn on and off when needed automatically, so choosing the correct pump with the best suited float switch is very important. If the wrong pump is selected for the wrong environment, it could cause the pump to stop working.
You will find that manual pumps usually pump to a lower level than the automatic version, but the manual models require supervision, where as the auto models can be installed in to sumps and left to do the job they are needed without being monitored.
The EGO 500 Submersible Puddle Pump is very popular as this is the only pump we have available that can be swapped between manual and automatic modes.

The swimming pool pump market can appear very complicated, so we have created 5 easy steps to help you choose the best pump.
Normally, you may consider replacing pumps like for like, however if the pump has failed prematurely, it may have been the incorrect pump and we recommend following our 5 easy steps to choosing the correct swimming pool pump. There is a tendency for people to buy bigger pumps than necessary. This is not recommended as you will suffer higher running costs, and run the risk of overpowering the filter, straining the pump and causing early failure.
The importance is not necessarily the power of the pump (HP or kW) but the flow rate.
According to swimming pool experts, as a general rule, all the water should be filtered within an 8 hour period.
To choose your swimming pool pump you need to know how many litres of water are in the pool, and then match this with the flow rates of a pump.
The following steps are a simple guide on how to do this:
Calculate the volume of your pool.
Volume/m3 = Length/m x Width/m x Depth/m
If the pool is not all the same depth, you can use the average depth.
Same Depth: Different Depths:
Average Depth = (shallow depth +deep depth)/2
Please note these images are for a rectangular pool.
If your pool is circular, you can calculate the volume using the formula:
Worked Example for Rectangular Pool (same depth):
If you had a 20m pool, which was 8m wide and 1m deep, the Volume would be:
V= 20m x 8m x 1m = 160m3
From step 1 you will be left with a value in metres cubed. This should be converted to litres.
1m3 = 1000 litres.
Therefore, multiply your volume by 1000 to give the figure in litres.
For the worked example, this would be:
160m3 x1000 = 160,000 litres
Calculate the required flow rate to circulate the pool in 8 hours.
As the water must all be circulated in 8 hours, you must divide the figure by 8 to give you the litres per hour figure.
For the worked example, this would be:
160,000L ÷ 8hours = 20000 L/h
Our pumps are rated in litres per minute, so the above figure must then be divided by 60 to give the litres per minute rate which can then be matched with one of our pumps, from either the SMP or SWIMM range.
For the worked example, this would be:
20000 L/h ÷ /60 mins = 333.3 L/m
You now should have a figure which is the flow rate required in litres per minute. Our swimming pool pumps have this figure detailed.
Select a pool pump from our range of swimming pool pumps which match your requirements. Ensure the pump has an adequate head for your system.
For the worked example, from the SWIMM range, the SWIMM 1000 would be suitable with a flow rate of 350 Ltr/min:
The size of your pool filter is directly related to the size of your pump. If the filter is too small, this will put additional strain on the pump as it tries to force water through the filter and meets obstruction, causing friction. This may eventually cause the pump to burn out.
Most filters have a maximum flow rating. Ensure the pump does not exceed this. For example, if your pump output is 250 litres per minute, you should not pair this with a filter that has a maximum rating of 200 litres per minute.
Avoid downsizing the pipe for the pump as you run the risk of the pump running hot as it is starved of water.
Both our SWIMM and SMP range of swimming pool pumps are reliable and come with a 2 year warranty from the manufacturer. As always if you need any further assistance please feel free to call our UK helpdesk on 0115 987 0358.
Flood Protection Solutions Ltd
Winter is now here, the nights are colder, the days are darker and the frost is in the air. Whether you live in a new build or an older house water pipes can be at risk of freezing and could split or burst causing flooding in your home.
There are hundreds of pumps available on the market but how do you know which YOU would need?
Well that’s very simple, below is our easy guide to help you in those emergency situations:
If you have a cellar, whether it be filled with fine wines, treasured items or just the stuff you never got around to unpacking, you want to protect all your possessions. One of the best ways to help protect your cellar from flood water is with a ‘basement pump’ the clue is in the name.
A basement pump can simply be placed in to the water. Turn on and away you go, it’s that easy! You may prefer to leave a pump there permanently and have an automatic pump which will turn on when water is in the basement. This is a popular passive system. There are many different models with different flow rates, this just means how much and how fast it will pump the water. Depending on the size of the room and the amount of water you can choose smaller or larger pumps. In the BPS range of pumps, there is a huge choice and the flow rates vary between 40l/min up to 220l/min!
If it’s a good old-fashioned frost that freezes and burst your pipes this is not what you want. After you have found the issue and turned off the water you are now left with a huge floody mess.
In this instance you may find a ‘puddle pump’ incredibly useful…
A puddle pump is simply placed in the puddle or vast lake of a mess depending on the size of your house. All you do is sit the pump in the water and again turn on. When the water has all gone, turn off and you’re home and dry (after you have dried everything of course).
Submersible Pumps or Puddle Pumps:
For this we suggest using a submersible pump in a sump chamber, or again, a puddle pump. The puddle pump means that no chamber is required. These pumps can be fully submerged in the water. Depending on the actual model of the pump these can pump down to as little as 1mm giving you excellent protection from that indoor swimming pool forming in your Living room. Again, there are different models with faster pumping volumes to get rid of the water quicker.
At Flood Protection Solutions Ltd we are incredibly proud to have recently supported the Cumbria Flood Resilience Showcase by donating a puddle pump.
Cumbria Flood Resilience Showcase Project
The Cumbria Flood Resilience Showcase Project was launched following Dr Peter Bonfield’s ‘The Property Flood Resilience Action Plan’ report published in September 2016.The project is led by the DEFRA Property Flood Resilience Roundtable. It is a government sponsored group which includes members of the Business Emergency Resilience Group (BERG).
The project has been fronted by leading flood resilience campaigner, Mary Dhonau OBE, alongside Adler & Allan, the Environment Agency and the DEFRA Roundtable. The project is supported by companies who kindly donate their time, expertise, services or products. At Flood Protection Solutions Ltd we donated an LSC1.4S Puddle Pump.
Puddle Pumps are a special type of pump which are ideal for flood resilience. Unlike standard submersible pumps, puddle pumps can pump water down to very low levels. The LSC1.4S which we donated can pump water as low as 1mm! This is ideal in flood defence for reducing any ‘residual risk’. If flood door barriers are installed to a property, it is very likely that some water will still enter through the bricks, mortar, or rise up through the floor. A puddle pump can help keep this water level low and reduce any damage caused.
Conventional submersible pumps are required to be at least partially (usually fully) submerged in water to prevent them from burning out; meaning that without a sump pit they can prove ineffective. Puddle Pumps are an ingenious design which solves this, as it allows them to be used in very shallow water without damage.
Within flood defence we believe too many people have the incorrect pump which will not work as expected in anger. We launched floodandwaterpumps.co.uk to make the best quality water pumps available with expert advice.
The donated puddle pump will be used by Botcherby Community Centre in Carlisle, which has been devastatingly affected by flooding in the past. Flooding is an awful experience and is the biggest threat to the U.K as a result of climate change. We’re incredibly proud to have been able to support this scheme and make a difference to the community.
We would like to thank all our customers, past, present and future because without your support, we would not be able to support great community flood projects such as this.
- Pumps as low as 1mm
- Ultra hard wearing
- Operate for extended periods with little or no water
- Used widely by hire, utilities and water companies
- Portable or fixed installations
- 3 year warranty
At Flood Protection Solutions Ltd we pride ourselves on supplying the best water pumps available, along with great expert advice and customer service.
Over the past 5 years we have grown into one of the UK’s leading flood defence companies, and have a fantastic team able to help with any enquiries. We supply water pumps ranging from <£50 to individual households, right up to supplying multi-million-pound contracts with large organisations, along with everything in-between.
We’re incredibly proud to have recently been shortlisted in the 2017 Damage Management Awards as ‘Supplier of the Year’, run by the British Damage Management Association (BDMA).
The BDMA sets the standard for damage management professionals as the certifying body. They provide training and certification for industry professionals and other across the broader insurance industry who are involved in the recovery, restoration and reinstatement of damaged properties.
The Supplier of the Year award is for suppliers of products or services who have exceeded expectation in areas such as customer service, quality, reliability and value for money. This must be aligned with the customers’ best interests and values.
We are therefore incredibly proud to be a finalist. The Awards dinner is on the 23rd November 2017.
We aim to continue to supply our customers with the best range of water pumps available on the market, along expert advice and next day delivery.

Puddle Pumps | www.floodandwaterpumps.co.uk
Puddle pumps are a hidden gem in the water pump world. Although they are fantastic products it appears that there is little knowledge on how they work and the use of them.
What is a puddle pump?
A puddle pump is a special type of water pump which is able to pump to very low levels of water without overheating or burning out. This removes the need for a chamber to be dug. Traditional submersible water pumps are water cooled and unable to pump to low levels. Electric puddle pumps can be used internally or externally.
Puddle pumps are perfect for use in flood protection and emergency response situations.
They can be used on most surfaces to pump away residue and nuisance water, which may occur because of seepage, rainfall, or flood water. Puddle Pumps are perfect for emergency response situations because you are able to position them straight onto a surface and can pump shallow water. This feature means that puddle pumps can hugely improve flood response – which is our key goal at Flood Protection Solutions Ltd.
One pump can help protect hundreds of people over its lifespan
Puddle pumps can prove very effective investments for councils, businesses, homeowners or agencies. They avoid the need for a chamber, which means you are able to use the same pump in multiple locations. It’s also possible to move puddle pumps to different places on the same site to remove nuisance water, or even to another site if necessary.
With submersible pumps, there is always a depth of water that cannot be reached. The following graphic compares a submersible pump with a puddle pump:
Where to use a puddle pump?
- Flood control
- Basement drainage
- Lift shafts
- Fixed installations
- Hire fleets
For the purpose of flood control, Puddle Pumps can be used internally or externally:
There are many different types of flood protection – a popular method is to use door barriers or guards as flood barriers, in conjunction with air brick covers. Whilst this will help buy time to move possessions, a house is not watertight. Water is likely to still find its way into the property by infiltrating through the bricks, the mortar and anywhere vulnerable.
At Flood Protection Solutions Ltd we like to use the example of ants… ants find their way into your property and often you’re unsure where from. Water is the same! Some flood schemes may include an internal sump and chamber to deal with this water entering. Fitting these can be disruptive and expensive. You are able to use an electric puddle pump internally to help remove any water that still enters the property. This can help keep the water level low, and massively reduce any damage that the flood may cause. A puddle pump such as the Tsurumi LSC1.4S can pump as low as 1mm and run dry for prolonged periods of time with very little, or no water at all due to the air and water cooling route to the top outlet.
With any flood defence scheme, there is always a requirement for a water pump. Puddle pumps can be used to effectively control seepage, rainfall, and rising groundwater, without the need for a chamber or sump digging. This gives flexibility and helps reduce any costs for the works. Puddle pumps can be used to help drain a site and protect it from flooding.
Flooded basements are a common occurrence in the U.K. Puddle pumps can be used when required, or installed permanently in a fixed installation with an automatic option available. Once again, a chamber is not necessary, so there is minimal disruption with using the water pump.
Puddle pumps are very versatile as they can either be in fixed installations or used in various locations. They’re fantastic products and we want to help more people with puddle pumps.
The main advantages of puddle pumps are:
- Cost effective
- Pump as low as 1mm
- No chamber required
- 3 year warranty on Tsurumi Puddle Pumps
- 2 year warranty on APP Pumps
- Help prevent flood damage
- Fixed Installations also possible
The Tsurumi LSC1.4S is a fantastic puddle pump and pumps water as low as 1mm. Unlike other pumps, it can even run dry for extended periods of time without damage. This pump comes with a fantastic 3-year product guarantee as standard and is the industry standard for quality. The pump is incredibly robust we believe it should be utilised more widely across the U.K. If you’re looking to pump flat surfaces, without a chamber, we would recommend the LSC1.4S. Water levels can even be managed in fixed installations with a SwitchH20 system of a Tsurumi Sensor.
Our flood protection goal
Did you know flooding is the biggest threat to the U.K as a result of climate change? Despite this, studies show that 67% of the U.K population do not know their own flood risk! At Flood Protection Solutions Ltd we want as many people as possible to reduce their risk of flooding, and puddle pumps can be a very effective and inexpensive way of controlling flood risk.
We believe that all communities, councils, and agencies should have a store of puddle pumps.This can help to reduce and mitigate the upheaval, expense and stress that flooding causes.
No matter what flood defence product you use there will always be a requirement for a water pump. This can be due to rising groundwater, overflowing drains, seepage and even rainfall. Flooding and its effects are unpredictable and therefore to be able to respond quickly and effectively with the correct pump is essential.
At floodandwaterpumps.co.uk we are regularly asked about irrigation schemes, or using water pumps to water plants.
Water scarcity is a huge problem facing the World, our population is ever increasing and the demands on our planet are ever growing. Early this year there were reports of impending hosepipe bans because of lower than average rainfall, leading to water shortages.
Plants need most water in hot and dry weather – which is when traditional water reserves are lowest and water companies may struggle to meet demand. At peak demand as much as 70% of our water supply may be used in gardens. Traditionally avid gardeners have used water butts to collect rainwater, and then watered plants using a watering can. These days can be long gone with a water pump.
If you want a high end, highly sophisticated system, the Divertron Pump is a fantastic pump for you. It is specially designed with an automated programme feature that makes it turn off and on with the opening or closing of a valve. Another programme prevents dry running, protecting the pump from damage. The pump can be used in a water butt or well and connected to a hosepipe, the minute you pull the trigger on the hosepipe, the pump will turn on and start pumping water, and when you let go it will also shut itself down. This means you can use rainwater collected in water butts to water your garden, or even wash your car, without using a tap, or having to turn an electric socket off or on, giving you ultimate ease of use. The pump can be left in the well or water butt ready for next time. Not only is it more environmentally friendly to use recycled rainwater, but you are also not incurring the cost of using water from a tap.
We have a range of pumps that can be used to enable you to water your garden. Our pumps start from just £44.88 with the BPS Submersible Puddle Pump – a very capable pump with excellent resistance to wear.
We are regularly contacted by local communities who water flowers using a water bowser or tanker. To water hanging baskets, a water pump is required to lift the water to the required height, and water the flowers. Clearly in open areas there is not a suitable power supply for an electric water pump. The Baby Battery Submersible Pump can be used here, the range runs off either 12v or 24v battery and they are easily connected to a battery. This range of pumps come with a flow rate of up to 69 litres/minute, similar to the performance of a conventional hosepipe. This pump is multi-use and very popular in boat bilges, general drainage and transfer.
If you’re considering using a water pump to help you with watering or irrigation, we strongly recommend you look at our great value hard-wearing pumps which are available with next day delivery. If you need any further help discussing your requirements, please contact us on 0115 987 0358.
A water feature can be a lovely addition to any garden or landscaping. The tranquil sound of running or gurgling water can create a relaxing atmosphere.
Ever since ancient times, humans have used water for its healing properties. We still use water for its calming properties; we holiday by the sea, and enjoy activities such as fishing, swimming and sailing. We visit spas and reinvigorate ourselves with soothing baths or showers. Adding a water feature into your garden can make the space more calming, as well as offering a lovely focal point. Whether you have a compact garden, or are landscaping a large site and installing a powerful fountain – we have the product for you.
A water feature requires a pump which is specially designed for continuous 24-7 running. Standard pumps will simply burn out under this intense use, or fail often and need replacing very regularly. Alongside this a pond may have debris in with fish waste or plant matter, and a pump which can cope with this is required.
As well as offering a sense of calm, a pond can also emphasise the sense of space as it reflects the light from the sky, and offers depth to the garden. With ponds, it is important to prevent them from stagnating, and therefore a pump which provides circulation Is recommended. The SMP Swimming Pool Pump would be ideal in this situation to help prevent stagnation occurring.
A water feature may be much more affordable than you imagine. Our range starts from just £85.36+vat with the fantastic TPS Submersible Pond Water Pump which is perfect for constant running situations. This is also a multi-purpose pump that can be used in sumps, providing added value. We highly recommend the TPS pump for your garden water feature. These are manufactured by APP Pumps with longevity in mind.
We also supply the MH Pump by APP Pumps which is perfect for ponds as it is available with fountain heads to provide your desired effect. The MH Pump is compact, but specially designed so that clogging is unlikely and it is ideal where there is fish waste or vegetation.
If your water feature is inspired by the likes of the Emperor’s Fountain at Chatsworth then we also supply a very powerful water pump for large water features. The HD-15 Pump has a flow rate of a huge 830 litres/min.
If you are replacing an existing water pump in your water feature, one of our water pumps should be suitable. We recommend checking the inlet/outlet pipe sizes to see if these may also need replacing, and checking the specification of your existing pump. You are then able to choose the most suitable one from our range.
If you need any further information please call our helpdesk on 0115 9870358.
