So, finally my brother in law has time to come and hopefully rectify the issue. Things I’ve told him to do: 1- put the pump on the floor (I’ve cut two nice pieces of heavy granite so the pump can sit on) 2- basically turn the pipes at the top of the pump around 180deg almost…so that the first...

The shower has one of those fancy Hansgrohe iBox wall valves behind...assume that should do the job?! For the basin, where would I fit a non return to the basin? Thanks

I will, thanks On another note, got to give it to Grundfos for their CS...I emailed them last week and a guy called me today. Told me that it looks like I have air trapped inside...that I need to put the pump on the floor / base of tank and that I should install some sort of "non-return flow...

Now that you say that I think it might only happen when I use the shower and when I turn it off it still drips for a few minutes…which is also a bit annoying to be honest since its an expensive Hansgrohe Raindance. Ideally you would turn the valve off and I would assume a couple of drops but not...

Thank you so much for all your inputs. There is no doubt that something has been installed incorrectly. Unfortunately his dad just passed away yesterday so I’m not even bothering him for a while. Can someone explain to me why the pump still keeps hunting on and off, even after no hot tap is...

Sorry! Doesn’t have one! Yes, 22mm from the cold water tank. The installer is my brother in law who has been a plumber for over 20 years…everyone makes mistakes I suppose! Hopefully moving it to the floor will rectify it. I still don’t understand why the pump continues to do that horrible loud...

But shouldn’t then the tank have an entry/connection on the side? Is it normal and easy to create one on a round copper cilinder? This diagram shows from the top!?

I can't remember exact but I believe they both are around or over 100 ltrs. ive never run out of water with the newer tanks (and I have 3 women in the house). My brother in law fitted the whole system. But the tank does have a side entry...ive checked. I would have to create an opening...sounds...

I would say in straight runs probably 7-8m to my basin and 9-10m to the shower head. Yes, the noise is just humming noise from the hunting...all the reviews online say the pump is quite silent which I find it very strange...the spec says it has a noise reducing operation...lol I can be sat...

Yes….if I turn the hot water tap or the shower thermostatic valve (even if on cold) on the new bathroom that is furthest away, even if for 5secs…it starts but then stays on and off doing that horrible loud noise for at least 20 minutes (counted today)! I thinking about trying to put the pump on...

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...
