Customer Question

Hi, I have a Glow worm 30cXi condensing combi boiler. It was serviced in August. I just bled the rad valves and I topped up the pressure from 0.9 to 1 bar. There is now a constant water leak from the reduced pressure zone valve. I have been told before by the engineer that a small leak is quite usual but this is much worse and not stopping after 2 hours.
The filling tube loop and elbow joint look OK and the leak appears to be coming from a short threaded pipe underneath the zone valve. There is also a small rectangular hole above the threaded section which lets the water escape if you bung the hole up with your thumb. Is there anything I can do, or should do until I can get a service engineer out in the morning? Thanks, ***** *****

You say the water is dripping from the PRV outside?

Yes, the filling loop is ok where the elbow joint goes into the zone valve, but the water is coming from a short threaded outlet on the underside of the zone valve

Sorry took long to answer, but I was filling a short length of hosepipe onto the offending outlet so I could get the water into the sink rather than staying up all night emptying casserole bowls!!
