Worcester 24i

[Teggs]

Hi all,

My Worcester 24i has developed a strange fault. At first I noticed that the pressure relief valve was dripping, having thought that that this was faulty I replaced it, however I did not pay that much attention to the larger picture!

Once replaced I noticed somethingn really odd. Afer repressurising the system noticed that the new valve started to leak after about an hour. At first I thought my filling loop might have been to blame but having disconnected this the pressure still increases.

The only explaination I can think of is that there must be a leak somewhere in the boiler that is letting my mains water leak into the central heating water. I can't be sure of this but if any of you experienced heating types could confirm this it'd be a great help.

Furthermore if this is the case which compnent is going to be the likely cause?

If you need any further information please let me know.

Terry

classic expansion vessel fault

it needs re presurring or replacing

Is it dripping when the boiler is running on central heating mode or not??

If its dripping even when off the the main heat exchange is pin holed and passing the mains into the central heating water as you said.

If its only dripping when on, then expansion vessle needs repressurising
as kevplumb spelt wrongly!!!
