Worcester Bosch 28i

[gareth365]

We have a Worcester Bosch 28i gas combi boiler which continually appears to lose its pressure. Water drips from the outlet pipe outside when the central heating is on. We have to increase the pressure through the filling loop on a regular basis.

We have had the pump replaced, the boiler serviced and the pressure bag pumped up, but it keeps losing pressure.

Any ideas?

your "pressure bag" or expansion vessel may have failed and pumping it up wont do diddley

Its sounds like your expansion vessel has lost its pressure you needs to get a heating engineer over to get the pressure up and probably change the prv.

Sorry, didn,t read correctly if water coming out out of shraeder valve on exspansion vessel needs new one.
