I have recently had a combi boiler fitted to replace an old fashioned system boiler..The problem I have is as the new system is under pressure and the toilet systern fills up quicker and now there is a very small drip which over the course of say 6 hours over fills the systern.It has only started happening since the combi was fitted a few days ago am I right in thinking it is due to the water going in at mains pressure as it has been ok for years on the old gravity fed system
Even if i adjust the ballcock down it will eventually still overflow..Is there anything I can do please
