Expansion Vessel leaking water - no air or water from Schrader valve?

[muustache]

Hey,

I've got a Grant Vortex that's leaking water from the seal around the expansion vessel - it's the round type about 50cm wide. The system is at 1.5 - 2 bar, but the expansion vessel has no air in it, and it's leaking water. No water is coming out of the Schrader valve either.

The system had been losing pressure the past couple of days, and it's been refilled a couple of times from the filling loop - but this morning it started leaking, and on checking I found the lack of air.

We had the vessel replaced last week, so it's esssentially brand new. It had 1 bar when fitting.

What could be going on?!

Any help very appreciated - it's snowing outside!

Thanks

M.

Duff expansion vessel, get them back out.

Meantime cap it off, drain a radiator and leave it empty as a temp expansion vessel.
