Leaky TRV

it decides to leak 2 weeks after final system charge with X100. Bugger downstairs too, so complete system drain.



I've noticed a small puddle under this valve and have just traced it to the very top of the valve on the outside of the white plastic threaded insert (pic). I could tighten the white insert and have done so and that seems to have stopped the leak - I'll check again in the morning. Is it buggered or have I got away with it?


I had exactly the same problem a month or so back - don't know how it suddenly happened as it's been fine for years.

Mine was an ETA valve from Screwfix (for what that matters).

It did the trick for me.

I went round some of the others just to check if they were tight - most were but at least one other was also loose... although strangely it wasn't leaking.

I actually went a bought another ETA valve as a 'spare' (and in case me tightening it didn't work) and found the design of the white insert had changed slightly - it now seems a bit 'beefier' (also has an extra o-ring fitted) and even has a torque rating for it in the instructions.

Thanks for that. Mine funnily enough is an ECA! do you mean ECA? Seems leak free so far.

Ah, yes, I probably did/do.

Given the design of the white bit has now changed it's probably a safe bet that they are known to be prone to leaking (although I've only had

1 of 12 do it).

I'm sure you'll be fine now it's nipped up.
