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?
