BotusBuild Posted Sunday at 10:32 Share Posted Sunday at 10:32 We are currently in a static van and have a slight leak on a towel rail. I'm confused about how to isolate in order to fix the leak as the "valves" don't look like I am used to, and I don't want to undo the "cap" (see pic) to find the water just pours out. Anyone worked on this kid of thing before? FYI, heat source is a combi boiler. Thanks in advance Link to comment Share on other sites More sharing options...
G and J Posted Sunday at 10:59 Share Posted Sunday at 10:59 I don’t think that’s a valve. I think it is a T junction. they’re used to put an electric element in as well as the water flow from the boiler. Link to comment Share on other sites More sharing options...
G and J Posted Sunday at 11:01 Share Posted Sunday at 11:01 So, depressurise your system, if it’s in a static I presume it’s not two storey, then undo that top bolt. I think there will be a rubber ring thingy (technical term) in there. 1 Link to comment Share on other sites More sharing options...

BotusBuild Posted Sunday at 12:24 Author Share Posted Sunday at 12:24 A simple case of bleed a radiator until the pressure reads zero? Link to comment Share on other sites More sharing options...
ProDave Posted Sunday at 12:29 Share Posted Sunday at 12:29 BEFORE you depressurise it to fix the leak, you DO have the fill loop needed to re pressurise it afterwards? 1 Link to comment Share on other sites More sharing options...

I can’t see on that pipework where a filling loop would connect. Link to comment Share on other sites More sharing options...

BotusBuild Posted 22 hours ago Author Share Posted 22 hours ago That is what I will be trying. Carefully. 🙂 Link to comment Share on other sites More sharing options...

Well I’ll go back to the bottom of the class then lol So, while I’m in learning mode, one of those two with a plastic T and chrome thumb taps must be the cold feed. I’d have expected a service valve or something to isolate the boiler but maybe there’s one inside the boiler. What’s the other one with the plastic T then? Hot water out or heating flow or return?
