Hi,

I have a Stuart Turner Monsoon water pump I believe it’s a ‘twin’ model and I have water tank in loft so I assume its gravity one.

The problem I’m having is that the pump keeps running when I turn the hot water off, for example had a shower this morning but when I finished and turned the water off the pump ran on. It’s happened before last few weeks but then I could solve it by just turning on a hot tap and letting it run then turn it off and it sorted it, this time it wouldn’t switch off and I had to switch it off on the fuse box as was late for work.

I’ve got a Stuart Turner engineer lined up to come and have a look but I wondered if there is anything I could check myself or is this a common fault ? I’m in a heavy lime scale area and I don’t have a softener so wouldn’t be surprised if its related to that ? I’ve read about the flow switch being jammed how easy is that for me to check / cheap repair ?

Finally if I need a new pump, should I expect a large labour bill, the current unit is easily accessed so I assume its just a straight swap and not to heavy labour wise ?

thanks

It will either be a faulty magnetic reed switch or a jammed magnetic shuttle.

Easy DIY job for anyone with basic electrical/plumbing knowledge.

Otherwise wait for the maker's engineer!

Hi Tony

I have the same issue, but if I bang and shake the pump it will turn off, but one it starts again it won't turn off.

I will give any DIY job ago. Is there a guide for changing the switch or shuttle.

Thank s
