My boiler is constantly running out of water pressure. It ran out last three months and again this week. Is there a reason for this?
Also an unrelated question I have the smell of bleach coming from the tap do you know of a reason for this as well?
If your referring to the pressure dropping on the heating side and no leak can be notice and the radiators are fully purged and the automatic valve on the top of the boiler is fine then I would be looking at the expansion vessel
