Boiler constantly losing water

[falkster]

We've got a brand new worcester bosch boiler but the previous owner either didnt register it or have the invoice so cant ring anyone up for warranty work.

Anyway, one of the pipes going out of the wall has a constant flow of water and Im topping it up every other day. It has only needed this doing for the last few weeks but I also noticed water on my car in the garage (where the boiler is) from a red valve that might have also leaked.

I know nothing about heating so need advice before I ring someone that will reem me.

Sorry my cock up, it's not a WB, it's actually a Main 30HE. I was told it was a Bosch by the previous owner as she was told by her builder (same happened with the dishwasher too)

Likely a leak under the floor somewhere. I had a similar problem. Tube of fernox superconcentrate leak sealer into a radiator sorted it.

It's a pipe on the boiler that's leaking through the outside.

In that case it's a piece of cake to swap. PRV is held in place with a small hex grub screw & once this is out it should be a sinch.

Check the pressure vessel also.

So you'd be able to mend it in no time??
