Power shower pump-life of it's own!!

[jgros456]

Hello everyone,
I have a power shower pump fitted in my airing cupboard that feeds my shower only. Some times at night it runs of its own accord when no other taps or appliances are on. Can anyone help with this strange and annoying problem?!!

Many thanks.

with the info u give its quite possible u have small leak on the pipe work from youre pump to youre shower or the shower valve is letting buy (dripping) is it negative or possitive pump how is it installed will help to pin point youre problem more

Many thanks all,
but I think I have cured the problem. The water in the tank was far to hot. Grundfos recomend the temperature to be set at 50 degrees C. and this seems to have worked! Keep you posted.
