Solved this by restricting the cold water flow from the isolator

Ok so I did remove cartridge on both the shower and bath filler and saw that they were retracting as I turned so appear to be working ok. What is crossflow?

Sorry it’s a combi boiler. Main 30kw. The boiler is fine though as it’s really hot everywhere else.

Hi everyone. I have a bath with overhead shower the bath is Bristan quest or something like, the overhead rainfall shower is a good brand from stax. Sp I think. Both cost over £150 so not cheap. But neither has water coming out hot enough just a little better than lukewarm unless I restrict the...

Thank you everybody for your replies. I didn’t touch the pipe Coming from outside. It seemed big enough and water pressure downstairs in kitchen was great so seemed little point in starting there. I ran 22mm pipe all the way up to attic for hot and cold. The kitchen went from 22 to 15 into the...

Wow. Thank you you’ve given me lots to think about. Thank you. Ok first thing I’m gonna do is start digging up the outside path and see the lead pipe coming in. Just at the entrance of house it’s lead then changes to 22mm copper. I was thinking of upgrading at this point to 28 and then running...

actually the tank isn’t ready yet. As in not installed but it will be soon. I’m just upgrading pipes first. No hot water at all on top floor when a shower being taken at middle floor. I’ve not done a pressure test outside. Is that something I should do first? Circulating loop is that the old...

Anybody got any ideas?

Hi everyone. Merry Christmas I have a 6 bed house (rented) on 3 floors plus a cellar with a vaillant 937 combi boiler. All the hot and cold pipes are in 15mm and the middle and attic rooms get zero water, not a drop if somebody has a shower on middle floor. It started off as one shared...

It was the diverter stuck on hot water!! thanks for your input. All lovely and warm now. Time to present the engineer’s bill to British Gas hopefully they will reimburse but I think it’s time to cancel these useless policies where they just want to sell you a power flush every time they pull up...

Hi thanks for your reply. It’s worked ok for 10 years or so but the older radiators were hosed out ten years ago and flushed through a few times. As the years have passed I’ve suspected bad piping and older rads. But apart from two in loft bedrooms all worked fine. since this sept I’ve removed...

Ok thank you. I’m gonna try that setting for heating load maybe find a way for it to revert to factory settings. Maybe when changing pump engineer played around with it. I wasn’t with him. Anyhow the diverter valve is being looked at tomorrow.

Oh sorry I don’t know what that is. A second engineer came out and increased the flow temperature to 80 and increased pump speed but I don’t know about heating load. If the diverter is stuck towards DHW then I cant understand why the heating still works ten minutes at a time (before locking...

Thank you for your reply. Ok firstly yes the return and flow are fully open. Secondly the pump was changed as British Gas came to address this issue. After he left it was still the same. I think they tend to just throw lots of parts at a boiler rather than fix the underlying problem. Time...

Hello all I have a Circulation problem with my vaillant boiler installed in 2012. It’s not that old. It was working Fine, never brilliant up to about September time when one by one I started upgrading radiators from the old single panel to type22 kudox with Drayton bi directional valves. Just to...
