O rings won't seal

[Dan Robinson]

I asked you what your experience of boilers is.


Is it just the one you illegally and poorly fitted?

For crap advice, see your thread on the Vaillant boiler.

calm it down san, lets not throw words like 'illegal' around hey, we both know the law allows competent workers on their own supply

You're not competent. Your own pictures showed that. Nor do you have an ecga.

Yes I can see where the two leaks are and I have posted pics in an album called boiler

Can you not post them directly into the thread? saving is hunting around.

In my experience the seals and washers supplied with boilers are not the thickness and diameter you find in standard high street packs. Really the guy should have sourced genuine washers and o- rings specifically for the boiler rather than just buy a pack of assorted ones

Also agree that if he uses the right size washers there will be no need for ptfe or other things. However if it's an old boiler he should deffo clean the thread and nut of the joint with steel wool or similar before tightening

The boiler man was unable to buy just the two o rings needed and had to get a complete set for the boiler, the pack clearly states that they are for a Ferroli boiler. The boiler is only five years old and I watched while he cleaned the o rings but they still wouldn't seal. Only at this point did he use sealant so that I could use the boiler.

I guess if no one has ideas I'll have to go without heating I just find it hard to believe that when we can go into space and head off in any direction we want that there is no way to get round a minor water leak from an o ring.

Looks like a service pack for the boiler so could week be the right of rings.

You can't appreciate enough how crap these boilers are.

 

[Dan Robinson]

Those picks don't specifically show the leak.

At the risk of being shotdown by Dan... it looks the the leak is coming from within the sealed chamber. Did he open that and have a look in there?

Front of boiler

pic one sample of the o rings
pic two leak area is on the silver cylinder behind the black pipe this is the one covered with the opaque rubbery tape
pic three the silver cylinder in front of the copper pipe leak is from the visible o ring above the section directly in front of the copper pipe
pic four is boiler from the front

No, but you can see the water as it comes out from around the o ring in both cases we were chatting when he had got to this point so I was able to see it for myself

Pic two shows where the leak is as I am not qualified to go near a boiler I would not tamper with it but I do know that is the problem on pic three you can see the water drops clearly below the black o ring there are two both in the middle of the centre silver cylinder one just under the o ring and the other a couple of centimetres below

Well I think one of the joints in the sealed chamber is leaking (the pipework in there are usually joined by clips)... the leak is dropping down and appearing on the silver pipe (but that's not the source of the leak).

Dan can you confirm my amateur diagnosis... and feel free to shoot it down in flames!

 

[Dan Robinson]

I'm on my mobile for the the next few hours. Will have a look later.

The area above the two o rings in both cases is dry

The ring that he used was the small thin one top left

If your gas engineer had taken that silver cover off the front of the boiler then he would have spotted the leak (assuming the system hadn't been drained). Wait to see what Dan says... because although he can be a bit rude, he does know his stuff probably moreso than anyone else on the forum.
