Sump Pumps

Sump pumps are submersible water pumps designed to remove water from a sump pit, basement, or low-lying area where water naturally collects. Sat at the lowest point of an installation, the pump activates as water enters and discharges it...

What is a Sump Pump?

What is a Sump Pump?

A sump pump is a submersible pump installed at the lowest point of a chamber, pit, or floor area where water collects. As water enters the sump, the pump removes it through a discharge pipe to a drain, soakaway, or sewer at a higher level. Sump pumps run intermittently rather than continuously, switching on only when water is present.

They are an essential part of any property's flood protection or basement waterproofing strategy, providing automatic, unattended water removal that keeps living and storage areas dry without daily intervention.

What are Sump Pumps Used For?

Sump pumps are used wherever water needs to be removed from a low point and discharged elsewhere. Typical applications include:

  • Basement and cellar drainage, often as part of a Type C cavity membrane waterproofing system
  • Flood control for properties at risk of groundwater, surface water, or river flooding
  • Garage and outbuilding drainage where natural drainage is poor
  • Lift shafts and inspection chambers requiring automatic water removal
  • Surface water drainage where gravity drainage to a sewer or soakaway is not possible
  • Construction and site dewatering for trenches, excavations, and groundworks

Automatic and Manual Sump Pumps

Sump pumps are available in both automatic and manual versions. The right choice depends on whether the pump will be left in place to operate unattended, or used on demand.

Automatic Sump Pumps

Automatic sump pumps include a float switch that activates the pump when water reaches a set level and switches it off again when the level drops. They are the right choice for permanent installations such as basements, lift shafts, and unattended properties, where the pump needs to operate without anyone present.

Manual Sump Pumps

Manual sump pumps are switched on and off by the user. They are typically used for one-off jobs such as draining a flooded room, emptying a tank, or removing water during construction work, where continuous unattended operation is not needed. Manual pumps are also used in attended flood-response situations, where an operator is on site managing the pump.

Manual pumps can also be integrated into a wider system where switching is controlled separately, such as via an external float switch or control panel.

Some sump pump models are available in both automatic and manual versions of the same unit, allowing the same pump to be specified for either application.

110V and 230V Sump Pumps

Sump pumps are available in two voltage options for UK use:

  • 230V single-phase is the standard domestic and light commercial supply, used in homes, offices, and most fixed installations.
  • 110V is the standard voltage for UK construction sites and is required by most contractors for site safety reasons. Most professional hire fleets and trade users specify 110V pumps for site use.

Choose 230V for domestic and permanent installations. Choose 110V for construction site work and where required by site safety policy. Some sump pump models are available in both voltages.

Choosing the Right Sump Pump

Three questions usually settle the decision:

  1. What are you pumping? Clean water, grey water, or foul water containing solids. Standard sump pumps handle clean and grey water. Foul water requires a sewage-rated pump with a vortex or grinder impeller.
  2. How much water and how high does it need to go? Flow rate (litres per minute or per hour) and head (the vertical distance from the pump to the discharge point) determine which pump model is correctly sized.
  3. Automatic or manual, and what voltage? Decided as set out above based on your installation and intended use.

Sump Pumps for Basement Waterproofing

Sump pumps are the active component of most Type C cavity membrane basement waterproofing systems. Water that enters the cavity is channelled to a sump, where the pump removes it and discharges it above ground. For basement waterproofing where pump failure cannot be tolerated, a twin-pump packaged system is recommended for redundancy, available in our Packaged Pump Stations range.

Common questions

Frequently asked questions.

What is the difference between a sump pump and a packaged pump station?

A sump pump is a single submersible pump that sits inside an existing chamber. A packaged pump station is a complete system with the chamber, pump, internal pipework, non-return valve, and float switch supplied as one ready-to-install unit.

How long do sump pumps last?

Service life depends on the pump model, duty cycle, and water type. Quality submersible sump pumps in typical domestic basement duty give many years of reliable service. Pumps used in heavy-silt, foul water, or continuous-duty applications may wear faster and need replacing sooner.

Do I need a backup sump pump?

For permanent installations where pump failure is not acceptable, such as inhabited basements or properties with valuable contents below the flood line, a twin-pump system or battery backup is recommended.

Can a sump pump handle sewage?

Standard sump pumps handle clean and grey water only. For foul water containing sewage you need a sewage-rated pump with a vortex or grinder impeller. See our sewage pumps collection.

How is a sump pump installed?

Installation depends on whether the sump chamber already exists. For an existing chamber, the pump is lowered in, connected to the discharge pipe, and wired to a power supply. For a new installation, a sump pit or chamber needs to be excavated and prepared first. Pump installation is site-specific and we recommend using a qualified installer.
