Quick answer: For protecting a home or business from flooding, buy the pump. Flooding, and surface water flooding in particular, can arrive with very little warning, and a hired pump has to be found, booked and delivered at exactly the moment everyone else wants one. A pump you own is already on the shelf. Small flood pumps such as the Stream SPP2-4 cost far less than most people expect. Hiring still makes sense for one-off, large-volume dewatering jobs.
We are asked this question every winter, and we understand why. Hiring sounds sensible: you only pay when you need it, someone else stores and maintains it, and a contractor’s pump looks more serious than a small puddle pump.
For flood protection, though, the deciding factor is not cost. It is timing.
Flooding doesn’t book ahead
The Environment Agency issues flood warnings for flooding from rivers and the sea. Surface water flooding, when heavy rain falls faster than drains can carry it away, is different. It can build in minutes during a downpour, in places nowhere near a river, and it is not covered by the same warning service.
That is why so many of the calls we take after a storm start with “it came in so quickly”. We saw it with the flash flooding in London and Richmond and again with the Birmingham storms.
Now think about how hiring works in that situation:
- Everyone needs one at once. Flooding is regional. When one street floods, so do the next ten, and local hire stock is quickly out on the road.
- It has to reach you. Delivery relies on open roads, a depot that is open, and a driver who can get through.
- It arrives after the water. By the time a hired pump is on site, the water has often done the damage a pump was meant to prevent.
- It may be the wrong pump. Hire fleets are built around contractor site pumps. These are excellent at moving volume, but they need a good depth of water around them to keep running, so they leave a layer on the floor. A puddle pump clears water down to a few millimetres. We explain the difference in what size water pump do I need.
Step 1: check your flood risk
Before choosing anything, find out what kind of flooding your property is at risk from.
- England: use the government’s check your long term flood risk service. It shows rivers and the sea and surface water separately, and surface water is the one many people miss.
- Wales, Scotland and Northern Ireland: Natural Resources Wales, SEPA and the Department for Infrastructure publish their own flood maps.
- Sign up for warnings where they are available, through Floodline.
If the map shows surface water risk, assume you may get little or no warning, and plan to have a pump on site rather than on order.
Step 2: match the pump to how you’ll use it
You don’t need a contractor’s pump to protect a home. You need the right pump in the right place.
Occasional shallow water, and someone will be there: the Stream SPP2-4 is a manual puddle pump that clears water down to 2mm at up to 70 L/min. If you’re starting from scratch, the Small Flood Pump Kit adds 6m or 10m of matched hose and fittings.
Water could arrive while you’re out or asleep: the Stream SPP2-4A is the automatic version, starting at about 20mm of water and stopping at about 10mm.
Larger areas, or behind a flood barrier: the EVAK Residox 400 moves around 205 L/min and pumps down to about 1mm.
Recurring water and a permanent solution: a packaged pump station such as the FPS Iguazu 635 sits below ground and runs automatically.
If you’re unsure whether you need manual or automatic, see manual vs automatic flood pumps, and if you’re starting with nothing, flood pump kit vs pump only explains why matched hose matters.
When hiring does make sense
There are good reasons to hire, and we’d never pretend otherwise:
- One-off, large-volume jobs, such as emptying a lake, a flooded quarry or a large basement after the event, where you may need a 4 or 6 inch engine-driven pump for a few days.
- Construction phases, where dewatering is needed for a fixed period and the pump will go back afterwards.
- When you want someone else to do the work. Some people would rather call a pump-out contractor or a drying company, and after a major flood that can be the right call.
What these have in common is that they happen after the flood, on a timetable you control. Protecting a property is the opposite: the pump has to be there before the water arrives.
Owning a pump: keep it ready
A pump you own only helps if it works when you reach for it.
- Store it with its hose, fittings and a non-return valve where needed, so it’s ready to go.
- Test it a couple of times a year in a bucket or water butt.
- Think about power. If flooding often comes with power cuts, read what water pump can I use without mains electricity.
- Run through our winter flood pump checklist each autumn.
Communities can share the load too. Our piece on creating a community flood store shows how a village can hold pumps centrally, ready before the water comes.
