Install the Shower Power Booster in 3 Easy Steps


The versatile Shower Power Booster can be fitted in most locations to boost showers, taps, combi boilers, radiators and entire systems.

The Shower Power Booster is supplied with everything needed to install it to either 22mm or 15mm pipework – in just three simple steps.

Choose a Location

The Shower Power Booster can be fitted to a water feed pipe in any location where there’s suitable access.

Due to the compact nature of the pump, it can be fitted unsupported to existing pipework at any angle or orientation.

The 12V DC power supply can be plugged into any convenient socket up to 15m from the pump (using low voltage extension cables).

Insert the Pump

Simply cut and remove 115mm of pipe. Insert the Shower Power Booster and tighten the compression joints.

The pump comes complete with fixings for both 15mm and 22mm pipework.

Plug in the Power Supply

The power supply can be plugged into any convenient socket (up to 15m away) without requiring an electrician.

As the Shower Power Booster draws only 15 watts of power, it can also be connected to a standard lighting circuit.

As it uses low voltage DC, the Shower Power Booster can also be positioned in bathrooms where 240V is prohibited.

Installation Notes & Tips

Before fitting, ensure that the pipework to be cut is isolated and free from water.

The Shower Power Booster must be installed after the vent pipe, otherwise it could pump hot water into the cold-water tank.

Carefully determine the direction of flow and which pipe leads to the cold-water tank and which leads to the outlet you wish to boost. The outlet pipe will typically get hottest when in use.

The Shower Power Booster can be installed in lofts but should be protected from frost.

When installing, do not hold the pump by the white motor.

Depending on the pipe’s diameter, the enclosed reducing set can be used. Inserts must be used when installing on to plastic PEX pipe. 

The Shower Power Booster does do not pull in air so does not require a Surrey or Essex flange.

PTFE tape or Plumbers Mate can be used sparingly but should NOT be applied to the screw threads. The water seal is created by the seal within.

Once connected to the power supply, the LED light on an SP2B will indicate the status of the pump:

  • Constant light indicates the pump has power
  • Fast flashing light indicates the pump has detected water flow and is running
  • Slow flashing light indicates there is a fault

If two pumps are connected, the first’s LED will shine solid blue while the second may flash. This is correct and simply indicates the flow to the second is lower.
