Let’s get started.
Step 1: Turn Off the Water and Power
Safety first!
Switch off the power to the shower pump. If you are unsure of the power supply location, it is usually connected to a fused spur near the pump or the main circuit breaker.
Next, turn off the water supply to the shower pump. If isolation valves are installed, then turn off both hot and cold water lines. If you are unsure about the supply lines, then you need to shut off your home’s main water supply.

Step 2: Drain the Water System
Before disconnecting anything, drain out any remaining water from the pipes to avoid a mess. Turn on the nearby faucet to release the water pressure and drain out the remaining water. Keep towels or a bucket to collect any extra drips.
Step 3: Disconnect the Old Pump
It is time to remove the old pump. Using an adjustable spanner or wrench, loosen the nuts connected to the pipes. Keep the towels nearby, bit of water may spill out when you do this.
Once the pump is disconnected, unscrew any bolts or screws securing it in place. Gently remove the old pump and keep it aside for safe disposal.
Step 4: Prepare the New Pump
Before installing the new pump, check the instructions provided by the manufacturer. All pumps are not the same, so double-check any specific installation steps for your model.
Wrap the threads on the pipe connections with the PTFE tape to create a watertight seal. It will reduce the chance of leaks.
Step 5: Install the New Pump
Carefully position the new pump where to be installed. Align the inlet and outlet pipes with the existing system. Once you are positioned properly tighten the nuts and secure the connections using the spanners. Overtighten may damage the connections, so tight enough to prevent leaks.
Step 6: Double-Check Everything
Before turning on the water and power supply, check everything to make sure of safety.
Check all connections are tight
Check PTFE tape is applied to all pipe threads
Check the pump is securely mounted.
Step 7: Turn the Water and Power Back On
Now, it’s time for your excitement. Turn the water supply back on, check for leaks, then restore power. Test the shower to confirm the pump is running smoothly.
Once the pump is powered up, turn on your shower and enjoy the improved water pressure!
Step 8: Test the System
Let the pump run for a few minutes to make sure it is working properly. Listen for any unusual noises. If everything is running smoothly, congratulations. You’ve successfully replaced your shower pump!
Tips for a Smooth Installation
Choose the right pump: Make sure your new pump matches your home’s water system (e.g., positive or negative head).
Install isolation valves: If your system doesn’t have them already install isolation valves during the replacement. They make future maintenance much easier.
Check the warranty: Keep your receipt and check the warranty on your new pump in case any issues arise later.
