Help - problem with boiler

[flunge]

The other day we blead our radiators. We refilled the pressure everytime it dropped and eventually it stayed on 1 bar on the gauge. This morning we woke up to a pool of water under the boiler. Also the pressure bar is now staying on 3. Its a combi glow-worm boiler.

Apparently we need a new water pressure valve? Is this correct?

It worked fine before we blead radiators. Coincidence its pressure has gone high or a simple fix?

It sounds as though the filling loop may be letting by.

We've had an engineer out who says the pressure valve needs replacing. Its a big job and the boiler has to come off the wall or he puts an external one in. Is he blagging?

:iagree: with Mike ... Is it the blue knurled handle variety fill valve on your Glow-Worm? They're a pain in the :ciappa:

Is it an expensive job? This engineer says he needs to replace a pressure valve!

If he didn't try re-pressurising it first then he's blaggin! IMHO

What would he have done to re-pressurise it?

He'd have had some kind of foot pump attached to the boiler to pump it up and drained some water off too to get the system pressure down to zero! Do you know if the pressure goes down when the heating cools down?
