What's this stuff that's appeared on my boiler?!

[Danceintherain2018]

Can anyone identify this cream coloured stuff? Not sure where it's leaking from or what it is. Can anyone advise? House is a new build, we've only been in a couple of weeks and it wasn't there then!

I can't see anything cream coloured.

On the gold hanging disc thing. It's a cream/beige colour!!

Ghost spunk?

An extremely slow leak leaving mineral deposits. Will be dripping down from somewhere. I’d probably get it checked but not panic.

Looks like a blob of expanding foam.

An alien embryo?

I'd say expanding foam, it's used to fill holes. You should be able to scrap it off. It will be from when the boiler was installed.

It wasn't there before though, it's only appeared in the last few days.

Mineral deposit from a leak.

What do I need to do? Can I wipe it off or should I wait and call someone?

Is it hard or is it wet?

That's a genuine question I'm not being rude 😂

I haven't touched it yet. Will find something to poke it with!

Just wipe it off then see if it appears aha

Not aha! AGAIN ffs.

yes.

I say expanding foam. Cut it away with a sharp knife. The "gold thing" is a brass stop-end, probably intended to be screwed onto the filling loop pipes to prevent them dripping.

As it is quite new you will probably find the outside is yellow and the inside is white.

It is completely insignificant.

I can't see it but I would say probably plumbing compound or Plumbers Mait, used to seal joints, they don't 'set' so if it stays soft, just wipe it off and keep an eye on it for leaks (assuming it is where I think it is). It might be that someone will need to come and seal it later with some plumbers tape if it leaks.

I can see it. Look on the right-hand cap, dangling on its retaining strap.

My eyes aren't great PigletJohn, what does it look like to you?

to me it looks exactly like a smear of expanding foam.

you might need to zoom it.

Sorry, I hadn't seen your previous post.

no prob mate.
