My shower pump works fine on one setting, such as hot or cold, but when mixed its pulses on and off. How can I resolve this?

When a shower pump starts to lose pressure or stops activating on hot or cold water, then turning the pump around can help diagnose the problem.

Watch our video on turning the pump around.

This is usually down to the natural flow of water, either the hot or the cold supply of water is not generating enough flow to activate the individual flow switches.  Salamander Pumps require 2 litres per minute per side to switch on.

If this is a persistent problem it may mean that you need a universal pump.  You can upgrade your shower pump to a universal shower pump by contacting Salamander Pumps.
