Shower Power Booster pumps are very reliable and have no inbuilt obsolescence so they last many years. When they do stop sensing flow, or stop performing as well as they did, the led light on an automatic SPB will flash or not flash, and the pump will behave in a particular way which tells the user what is wrong. With a customer care package we will not only advise on diagnosing problems, we will listen to recordings of your pump running, review photos and sketches, and we will suggest solutions.

If you have a mixer tap or shower which is pulsing then reducing the back pressure may stop it pulsing.
If you do not have a mixer then pulsing pumps are either due to lack of water or in very rare occasions air in the pipes.
There are several steps to identifying where you might have created excessive back pressure and its best to look at the easiest things first unless there are obvious causes of air locks.
Shower Head
The shower head is not the cause of fluctuating pressures but changing the shower head could solve the problem. A shower head will create a back pressure as it restricts the flow deliberately to accelerate the water to create a nice spray pattern. Change the shower head, remove any flow restrictors in the shower head and you may reduce the back pressure and solve the problem. If you physically remove the shower head and it still fluctuates then you know changing the shower head could solve the problem. If it’s a tap it could be a gauze filter on the tap spout that needs removing.

Shower Hose
If it is not the shower head then could it be the shower hose is inadequate. Some shower hoses have an internal bore of 6mm or 8mm and needs to be replaced with a high bore shower hose (minimum internal bore 10mm). Remove the shower hose and the flow still pulses then change to a 10mm hose (but change to a high flow shower hose anyway as it is a good way to reduce hydraulic losses)
