Yes I agree. I gave the tech team my feedback but he was adamant that was was not the pump but its clearly setup to allow flow to travel between the 2 sides. The positive head one is also significantly quieter so this is certainly the way to go for me. Thank you for your advice. You've been...

So I did the xover test and no water came out. When I run just cold water, the 15mm pipe gets hot and I can feel the hot water pullung through and up the cold outlet. When I run the hot water I can feel the cold running through the pipe and cooling the hot outlet. It seems that its made to do...

I do suspect it is running in parallel which does allow flow to dilute either side. I've attached an exploded view of the pump. Nothing stands out to me. I did try something like this and when running just the hot, the 15mm pipe was very hot and the cold outlet was hot Doing the opposite kept...

Just got off the phone to stuart turner and they looked at the video and said the test is a pass and the pump is fine. They said it is something after my pump but it feeds 1 mixer tap, 2 individual taps in my bath and hot water to my kitchen tap. He didn't know what else to say as the only time...

That pipe is completely clear with nothing in it. When I took it apart I I checked the NRV's in the flow switch assembly and they had no debris in it and I blew into it to check it was sealing which it was, but it does allow air to flow through the 15mm and into the opposite outlet. I did this...

I took the 15mm pipe out to see if there was anything that could be blocked from the inlet sides but looked all good. I get drips coming out of the taps when doing this test. I checked on a mixer tap and my single taps in the bath. I only get flow straight out the pump. Head max is 3bar Pmax...

Its the valves on the outlet of the pump. The test I was told to do was to close the inlet to hot and outlet to cold. This was to force water through the valve and out of the hot and then to do the reverse. They said a trickle/low flow is expected but if its high flow then the valves have...

Hi all, I recently installed a 3bar twin universal stuart turner pump and I am having a strange issue with my cold water coming out hot. The cold water from my taps come out warm then goes cool then goes back to warm and stays warm/hot. The inlet pipe to the pump is cold as normal but the...
