Condensate pipe weeping

[wedge69]

Hi,

We've got a small weep/drip from where the grey condensate drain connects to the white pvc pipe (see picture).

Does this just push on, or does it need to be glued - can I do this myself or do I need to get someone in to do it?

Thanks!

It's a push fit, just pull it off & push back on having first smeared silicone grease or similar around inside of female part.
If that fails, pop a hose clip on it.

I've not taken it off yet, just tried giving it a good shove down first...

Is it really just lift off and push back on, because I really don't want to mess this up

What's the purpose of the grease? Lubrication it to help the seal?

Follow the above .

Thanks. I've ordered some grease and some hose clips

I think I’ve only seen them on the inside of boilers.

Follow up question. What temperature should the condensate be? I notice the water is reasonably warm, but not hot like radiator water. I assume this is just due to the proximity to the rest of the heating parts?

No idea as I’ve never measured it, but it’s part of the combustion process, so reasonably warm where you’re working by it.

Thanks, just wanted to check it was condensate leaking and nothing else

Vokera's come with them to connect to the 19.5mm, they use the same type of flexi's

What temperature should the condensate be?

It is formed at the bottom of the heat exchanger @ around ~50 deg C, so as the boiler is working and creating condensate it will be warm.

I haven't had chance to do anything yet as have been at work all day.

I did however phone the Vaillant customer helpline, who weren't much use. They were just adamant that it shouldn't leak, and all I could do was take it off and put it back on again. Don't use any kind of clip as there needs to be an air break, but not sure what they meant by that

 

[wedge69]

Ok, I've managed to take it off. I can see how it's ridged inside to sit on the pipe. Is there supposed to be a washer in there or anything?

No washer ,or anything else inside are required.
