Anyone know about shower pumps?

Found 19th Apr 2010
Our shower pumps gone very wierd over the winter. Turn it on and sometimes it wont kick in for a minute or so then does, other times we have to put a fan heater beside it for up to ten minutes. We discovered the fan heater fix during the winter, when we thought it was pipes iceing up - but its now roasting up in the attic and yet still we have to turn the fan heater on to get it to work. Sounds like its on the fritz anyway - any ideas if they can be taken apart and fixed or is it best to plug a new one in?

Sounds like the flow switch not kicking in, don't know why a heater would help it though.
Quite possibly an air lock too if the pumps in the loft.

Sounds feasible as theres no flow when you switch it on - would heat do something to the air in an air ock? Expand it? Still not sure why the pumps in the loft mind, apart from the fact its damn noisey!

eh? They aint exactly tricky to fit mate. Mine just plugs into the electric and you then connect four water pipes to it (universal fitting).

if you still want a plumber to do it, at least get the pump yourself as a plumber could well double th price you can get it for.

maybe google the service manual and take it apart yourself and have a look. Nothing ventured and all that :-D

very bad idea to put an electric fan heater in a shower room, also the shower must have one single cable running direct from your consumer unit to comply with safety.

Yes that sounds a good idea - we do have a scale problem so maybe its clogged up.

Can you stick that scale remover for kettles and the like in a shower pump?

Anyone know if the wiring in is fairly straightforward?

Just an update, apparently the shower pumps got power coming to it but the plumber thinks its a problem with the flow valves not getting enough pressure to trigger them. Therefore he has recommended a negative head pump (?) that should apparently boos the flow.

I have a similar problem too if my shower head is at full height. The shower pump sometimes refuses to turn on.

Once, I lower the shower head to its lowest level then the increased pressure sets it off


your problem is that your pump is in your loft ( :w00t: ) so the pressure will be very low.

Yeah - just seems strange its worked fine for the past three years - and why the heater being switched on seemed to help, thats a mystery!

This gets weirder and weirder. Plumber confirmed to me elctric was getting into it. I rang manufacturers on his suggestion to see if they do this negative head kit. Their senior engineer said there would be no need for one if it had been working succesfully for the past few years. He suggested cleaning the filters. I had a look at them, one was slighly gunked (the hot feed) so I cleaned it off. Tried the shower again, no dice. Then as a last resort I ran the fan heater in the pump cupboard for ten minutes - lo and behold it starts working again! Its got to be something to do with the action of the heat then - is it expanding some rubber in the pump? or the pipes going in (they are plastic type). Its truly bizzare!!! Anyway glad I dont have to fork out for a neg head pump kit - although maybe a new pump, unless its something inside that can be replaced that working when heated.
