Customer texted, wants a TRV changed, not been to see it. I've done many of these. 99% are on straight forward vented or sealed systems so I either bung the f+e or create an airlock and then top up the pressure after.
I texted back asking if he had a combi or tanks in the loft.
He says he "has a megaflo and the rad is on the hot water circuit so still on when heating is off and the hot water and heating is from a Rayburn cooker." He dealt with the tanks in the loft question by adding he has a "dry loft." Which I guess means no.
For a semi-skilled fast-track chump who sticks in his very narrow lane of jobs (mostly taps and toilets) like me this is throwing a few confusions into the mix.
I'm guessing it's most likely the rad is still on the heating circuit but is just plumbed in in a way that means it gets hot with hot water as I've asked about this before on here (and just about understood the reply.) I also seem to remember you can put a rad on the hot water circuit but it needs to be a special type and expensive and therefore rare.
I don't understand how the Rayburn cooker factors into anything and this has always been a blind spot in my knowledge which - where I live - has come up about 3 times in a decade and not been something I've needed to understand.
So given his supplied info - what would you do on arriving to check to your satisfaction that you knew how to isolate the flow to the pipe feeding this TRV and change it? And by what method would this likely occur?
I'm hoping the hot water circuit claims and Rayburn are irrelevant info and I basically just need to find a filling loop and pressure guage to relieve and the re-top up the pressure.
Thanks
