ANYBODY TELL ME WHAT THIS IS?

[Pigbristle]

Had a problem with water leaking out of the Air Vent on my Worcester 9.24.

Now I know I can buy a new Air vent here....

but I don't think thats the problem!!

There's this "Valve spring thing" that connects to the bottom of the air vent...........

But I can't seem to find out what it's called, to enable me to try & buy one.

any help would be much appreciated.

dont worry about it buy an aav with the correct thread.

Just buy a complete vent for the boiler, they are cheap enough.

It's an isolating valve. When the AAV is unscrewed, the spring pushes the plunger up; it should seal against a seat, stopping the water coming out. It is reopened by screwing the AAV into the fitting. It shouldn't come apart like that.

Anyway, they're carp. You'd be better off to fit a 1/2" lockshield (or screwdriver operated) ball valve.

You should have an isolating valve, i.e., a proper IV, below an AAV because they're liable to get debris in the seat and start leaking. As you've found out.

Whilst I know that many homeowners will do anything to save a few pounds, an AAV is so cheap that they are easy to replace rather then clean.

Depressurising is again very simple so that little device becomes redundant and even when supplied with an AAV I dont bother to fit them. Even if you tried to use them as intended they usually leak anyway.

It wasn't about being cheap!!!

I thought this was an important part of the vent mechanism.
And all the sellers on the Internet didn't mention that this part came with it.

If I had known, all that it did was seal off the water when you removed the AVV, I wouldn't have bothered asking about it or fitting it.

Anyhow I have since bought an avv (including the Self Closing Valve item).

thanks for all who helped ;o)
