Power Shower Pump Problems

fatboyonadiet

Within the last few months we've started to use the power shower in our en-suite (never used it before!), the shower itself works fine, but what I've noticed in the last few days is that when we using any hot water taps in the house the pump seems to come on for a few seconds.

It happens just after we shut the tap, the pump kicks in and then goes off.

Is this anything to be worried about? The shower itself doesn't come on.

The pump is in the loft and the power shower was installed a few years ago (before we moved in), but isn't the original shower that was in that room.

It's probably nothing to worry about - just the pressure wave from the tap triggering the pump's pressure sensor.

It's ~probably~ because the hot water supply to the pump is a branch off the pipes that serve the water downstairs, but that's not unusual - it's often difficult/impossible to run a direct, dedicated supply.

you could have air in the pipe suppling the pump as the pump is prob the highest point so air could be travelling up the supply pipe (& could be connected into the vent pipe), i never fit pumps in the loft as it states in the MI pumps should not be installed in an area subject to freezing & as they need air flow around them you can't lag them either

Mmm pumps in lofts are unlikely to meet the MI minimum head of water requirements.
They will probably draw in air and cavitate!

Would suggest moving it!
