The easiest way to deal with insufficient water pressure is to install a new shower pump. The following instructions will show you how to perform this procedure.

Required Tools and Materials

5 amp plug point
15-mm pipes
Pump
Surrey flange
Isolating valve
Concrete paving slab

Step 1

Place the pump as near the cold and hot water storage tanks as possible. Try putting it 30 m under the cold water tank and about 4 m from the hot water tank. Set the pump as low as you can and the water input head as high as can be. Ensure the water area around the pump has good ventilation. Put it on a concrete slab to keep the noise down.

Step 2

Put the shower pump on the slab in a horizontal manner. The pipe outlets must be set upwards. Join the pipe to the cold water tank. This should be done before linking the pump to electricity. Hook up the supply pipe to the cold water supply. Ensure the supply tank has the right capacity so water flows properly (i.e., 8 liters a minute).

Step 3

Link the pipe to the hot water outlet. Now connect the pipe to the water cylinder using the flange. Affix the thermostat to the pump so the water doesn’t get too hot.

Step 4

Set up the isolation valve and join it to the shower inlet. Make sure the valve isn’t fastened too tightly. Put the brass ring between the pipe and nut.

Step 5

To finish installing a shower pump, connect the pump wiring to an electric switchboard. Make certain there is a 5 amp plug for this connection.
