Re: Gas safe engineer / Plumber types?
SmellyRobert HopkinsIf it constantly drops pressure you've got a leak somewhere. Check all rad valves etc and look for any signs of a leak, rust marks on carpet etc
Vailants come with 7 year warranty if fitted by vailant approved engineer. Also might pay to find valiant approved engineer to solve than someone hitting and hoping but sounds like thermostatic valve is f'ed
I think the warranty only holds if the boiler is serviced annually, which I stupidly didn't do. I have had the thermostatic valve replaced which has helped slightly, but the problem seems to have crept back since the Mrs has had the heating on this week.
That could be diverter valve then. Where are you ?
