Hi, I've got a dripping tundish on our unvented OSO water heating tank.
It started off as quite a flow, which got worse when I turned the TPR valve, but has reduced back to a drip when I drained the system and recharged it following the instructions on the side of the tank.
Before I investigate more, and probably call in a registered expert if there is no obvious DIY fix, would anyone out there be able to help me identify what the three pressure relief valves that I seem to have do and what they are called?
If you look at the photo, the bottom valve is what I think is the Reliance TPR valve (marked as such with a set pressure of 10 bar and a set temp of 95-98C). The next one up, which links to the TPR with a braided pipe, is marked RWC 8bar. The top one is marked 2.1bar.
So the questions are: what are each of the valves, and is there anything else simple (and safe) that I can try to stop the drip?
Thank you.
