Hi exedon ,
The EV flexi pipe is brand new on this one, and the isolation valves I’m speaking of are in the top of boiler (brand new full bore butterfly valves sept 2024) - not the pump valves .
Also there’s full bore butterfly isolators internally - on pipe work before boiler - but that...
Am I right that the vessel shouldn’t be really heavy as in full of water heavy ?
We’ve been having the pressure building up and after 2/3 days sheds its pressure via the PRV as I put a sandwich bag over the pipe and it was full at same time the boiler was then not working and pressure at zero...
So I think it may be the expansion vessel - it’s a big grey 24L one , this shouldn’t be heavy as a concrete block should it?
I’ve pressed the valve in , and water cones out ?
Do I need to pop new one on.
Cheers
Thanks Johntheo5 , sorry for delay in replying - very unwell. that is most helpful . I will try this when I’m better and see what the result is and I’ll update.
Hi Guys,
Wet plumber 33 years experience here.
We have a Grant Vortex Pro 36Kwh external oil - sometimes I hear the boiler cycle when heatings off (after bed time) then next morning no pressure .
Seems if the heatings on all day , switch off 10pm - then sometimes next morning cold house...
Yes exedon this is the 90c version, it does make you wonder why they paint these exterior boilers greens & greys - dark paint attracts the heat - even though supposedly allows them to blend in .
Hi Exedon , quick question for you .
I’ve just noticed the fire valve sensor on my vortex pro is in a clip above expansion vessel is that the correct place ?
Cheers
