Weepy boiler valve

[ismellburning]

Morning all,

My Ariston boiler has developed an interesting fault.

When I turn both taps on to recharge the system (after draining to remove a radiator), the left-hand one leaks. It's only a drip, and it stops when I close the taps, but I don't like it.

I've tightened the screw inside the black plastic tap to no effect. The drip is coming from the top of the same.

Is this something I can resolve myself or is it plumber time?

The troublesome tap is the one on the left.

All advice gratefully received

Needs a new filling loop. Will have to be an Ariston specific one IIRC as it is a smaller than normal thread. Not difficult if you can change a rad.

They always leak on the LHS, the new one will leak eventually.

But if you insist...

Don't forget the washers too.

Sweet! Cheers for the link.

Quick edit You say washers, are these the chaps? http://allaristonspares.co.uk/ariston-gasket-38-1pc-573521-microgenus-ii-2428--31-11473-p

Ta!

Woops, as you are. Checked the repair manual and yes they are.
