Happy New Year everyone!!
We were away last month and when we came back I notice central heating pressure dropped to 0. Didn't think much and topped it up to 1.5 bar. Exactly a month later, pressure dropped to 0 again last night. This time I know something is very wrong.
After some investigation, I believe I fount the leak on the magnetic filter connected to the return pipe of the boiler. It is a Sentinel Eliminator TurboGuard. The leak is from the bleeding valve. I tried the bleeding pin itself, the leak wasn't coming from that, but the housing instead, likely from the thread. I tried to tighten the housing maybe by a quarter turn, and the water stopped. This morning I see water dripping and accumulating again, so I tighten it a bit more, maybe another quarter turn, and the leak stopped again. The hex head can be tighten further, but I am worried I might cause some damage to the plastic filter housing (or I already have) by over tightening, so I stopped.
I did some search online and couldn't find anyone reported leaks from there. And I suppose the bleeding valve housing wouldn't just loosen on its own? So I assume I still need to do some repair works, but not sure what. I might have a few options.
1) Replace the whole filter - I think I need a plumber for that and it will cost quite a lot.
2) Replace the o-ring (assume there is one), but I can't determine the size, and can't find any info on the o-ring size to use.
3) remove the valve housing, apply PTFE tapes and fit it on again.
4) Tighten it more until it stops (as it can be tighten further).
Any suggestions please?
I attached some images if my description wasn't clear. the red lines are where the waters are leaking from.
Thanks
Ken
