    Hi all, I'm having issues with fitting a new shower pump, my old pump stopped working suddenly and I tried common troubleshooting with it which did not work and I saw alot of advice online to just replace it. so I replaced it like for like it's a twin impeller pump from wickes.

    I turned all the hot and cold water off, removed the wiring, then unscrewed the pipes connected to the old pump and removed the old pump. I then put in the new pump and connected it up exactly how the old one was, I turned the water on and with the power to the pump not connected, turned the shower on and ran it cold for 5 mins then hot for 5 mins. I then wired up the pump using the same wires as the old pump to the socket and put a fuse in it.

    From instructional videos on pump installation when I now turn the shower on the pump should start up but it doesn't and I can't work it out help!!!!

    Does water come out the shower head ?

    And does the pump kick in when the shower head is lowered?

    Does it start if you open the cold OR hot water tap on the basin?

    Which brand & model of pump is it?

    If you have a good size magnet run it up and down the inlet pipes near the pump, thinking there is a flow switch not activating.

    Well that's just made my afternoon.

    Not quite what I thought now I've had another look.

    Should be on the floor and the pipework needs a bit of adjustment.

    Think I made the same error as you when I first looked at the loops. :)

    great so the bloke who fitted my old one and put the pump there has made a pigs ear of it and I've just replicated it with the new one.

    so what should I do now? cos there's no space in there for it to go on the floor. and why did the old one work for 3 years when it was installed exactly the same as that?

    Time for a cuppa and a short break whilst you look at the installation manual again.

    I would say duff pump check there's power going to the pump first either a multi meter or voltage stick

    And the pump looks like a positive pressure one to me

    I take it the pipes aren't suppose to loop then? I wonder what the plumber was thinking when he set all this up

    No, what I meant was at first glance I thought the flexi`s went from one chamber to the other.

    The one you have fitted is NOT universal. You have a positive head pump fitted in a negative head situation.
    TBH as I cant see the whole installation I'll not offer any more except to seek advice from a professional as you will not get it to work as is.
    Good luck.

    it says it's a universal pump in the instruction manual?

    Same as I did right now, I really had to look much more precise :)

    I would have thought universal shower pumps still have a vessel fitted.

    You could try fit a pair of valves on live side to shower and release water into a bucket and then reconnect to shower once you get water through it the pressure switch should activate after initial start seen similar jobs like this not right but its what we are up against as I always say it's harder to do a job wrong then the right way best of luck with it

    Big difference in price between a positive and negative head pump here

    If there is power going to the pump, then try bleeding the air out of it and forcing the water to the shower. This can be done by opening the couplings on the hoses going away from the pump. this should kick the pump in if there is power.
