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!!!!
