whilst drilling through my outside brickwork to sort my stopcock out i accidently drilled through my water in mains...well, i wish i hadnt done that!!i had to call the water board out to turn the mains off in the front street as i couldnt acces it!...anyways everythings gone wrong since,my ferroli combi boiler isnt working correctly,the hot water works but no central heating...the washing machines packed up its doing strange things like trying to run a cycle without letting the water in although theres flow through the pipes,the toilet cystern started overflowing and leaking through a corroded overflow pipe into the wall cavity.What im wondering is,is it a coincidence everything has gone wrong or is it due to my error with the water mains?ANY HELP OR ADVICE GREATLY APPRECIATED!!
