Hello everyone.
Hope anyone can help me please. I got a plumber to install a shower pump Grundfos STP 3.0 B to get enough pressure to run a shower and hot water in the basin on my new bathroom. Also bought this one since later I plan to put a new shower on the old bathroom (currently it has an electric shower).
Problem is that, this pump which is supposed to have a low noise operation etc (many reviews online state how quiet it is), it’s nothing like that for me. It’s really noisy and it’s does this pulsating on/off vibrating noise…really loud…so much so that my neighbour can hear it on the other side of the wall. Even worse is that, even if I turn the shower or hot water basin tap on for 10 seconds, it then continues to do the same loud pulsating noise for a good 20minutes after…nothing happens when I turn the cold water tap. Surely this is not normal. It was not a cheap pump!
Is this a sign of a faulty pump or installation issue. What shall I do?
For info, a photo of the set up. I also put a new hot water tank next to it and the cold water tank is in the loft directly above this photo, maybe 1.5/2m above.
For info, I’m completely ignorant when it comes to these things as well, which doesn’t help!
Thanks in advance
