I returned to my home today after being away for 2 weeks and discovered my Baxi boiler had been leaking all over the floor and the overflow had been constantly running outside. The pressure was almost at 4 so turned on the boiler and ran the hot taps (don\\\'t ask me why) The pressure went down and wouldn\\\'t stop! Instead of trickling, it was pouring out of the overflow. I\\\'ve turned it off and went off to hide. The heating has not been used since June due to me not being able to live there due to builders being called in after an insurance claim so was wondering if they could possibly have put a hole in a pipe somewhere? There are no visible leaks anywhere and the heating and hot water were both working. If I\\\'m forced to live with my parents for much longer I may crack. Was just hoping for a few possible explanations before I call in the professionals. Many thanks
