I am writing this blog as a way of allowing others to identify and solve the problem of a ShowerPowerBooster being starved of water. If this is what your installed SPB sounds like this is the blog you must read.

As long as there is water to pump the pumps will pump and the pitch you will hear will be constant. If you turn off the taps and showers and plug the transformer directly into the cable from the motor (the white barrel), you will hear a constant pitch.

To confirm that the pump is being starved of air simply leave the pump for a few minutes and then get someone to turn on a tap or shower whilst you observe the pump. The pump will pump at a constant pitch for perhaps 6 or 7 seconds and then it will start to pump erratically as shown in the video. Also, if you measure the flow from a tap you will find that the flow at maximum flow of tap or shower will be perhaps 2 to 4 litres a minute with or without the pump plugged in.

Having determined that the pump is being starved of water there are several steps you should take to sort the problem.The restriction in flow is somewhere between the pump and the base of the cold water cylinder.

FIXING THE PROBLEM
Operate the Valve between the bottom of the cold water tank and the bottom of the hot water cylinder
Check this valve is fully open – turn fully anticlockwise to open

Blockage at Base of Cold water tank.
Check for silt in the Cold Water Tank as this can block water flowing from the bottom of the cold water tank. I suggest you do this second because it is an easy thing to check.

Replace the valve between the bottom of the cold water tank and the bottom of the hot water cylinder
I suggest you buy a new 1/4 turn 22mm valve before you remove the existing valve and inspect it.Things have a habit of breaking when they are used so infrequently. After taking it out you can see its condition and how it operates. At this time you may decide not to replace the valve but its good practice to fit a new valve.
HINT 1: You can buy a rubber bung to plug up the outlet from the cold water tank from inside the cold tank with water still in the tank.This will save you the trouble of emptying the tank which will also risk getting air into the system.
HINT 2: Before finally reconnecting the valve, turn to fully open and flush some water into a bucket. This will eliminate the unlikely chance that there is a blockage in the pipe itself or even a second valve you did not know existed.

The Hot Water Cylinder
Sediment at the bottom of the cylinder can be flushed out from the drain valve at the bottom of the cylinder (or you may decide to replace the hot water cylinder). You should now have a fully operable valve and be able to turn off the valve to fully isolate the hot water cylinder and back flush the cylinder.
