Sorry

Right I have a leak on my combi boiler. The old mans been round and had a look (45 years gas service engineer) but to be honest he doesn't like messing with stuff in his own time and even less so for me its still leaking so I've decided to have a go at it myself.

I have a joint with an O ring between two plastic components on the hot water out side of things, now I've had it off and the O ring looks sound but I took it off and turned it over anyway but its still leaking, so then I decided to take it off and wrap some PTFE around the O ring and it still leaks, now I'm not keen on how this joint is held together, it just pushes together and is held in place by a metal U shaped pin

Is it worth trying some sort of sealant as well or is something fucked?

 

here are some pics Tiff, although I cant get any pics of it apart as I've only just put it back together with a bit of instant gasket stuff

Combi is a glow worm compact 75E.

What I'll do is take it apart again tomorrow (as no doubt it will still be leaking ) and take some pics of the joint, although its a pretty simple straight forward O ring style connection.

Looking at it from the front


Looking from directly underneath


Underneath again but slightly to one side

 

I've tried that mate, so it sounds like it could be the housing thats cracked? I bet thats gonna be cheap

 

Right its not as bad this morning, do you reckon its worth trying a bit more PTFE and some sort of sealant?
