Hi all - bit of advise please
had a job through today to replace a fortic indirect cylinder, after speaking to the householder, It seems hes had a heating engineer out to the cylinder on 3 occasions in the last week, each time the cylinder had boiled over and flooded the hallway - heres what he replaced;
the 3 way valve
the ball-valve
tried putting a better fall on the overflow pipe?
after the 3rd time he told the householder that there was probably a crack in the coil that was causing it to boil over? - first time I've heard of this? - checked the hot water coming through the taps and it wasnt discoloured/rusty etc - he said he checked the cylinder stat and it was shutting off the boiler when it should have and the immersion heater isnt working and not used anyway so I dont think its that - any ideas chaps? - the only thing I noticed on the cylinder is the overflow outlet is higher than the ballvavle (half an inch from the top of the header-tank) hence why it probably flooded out - I'm not bothered about putting a new one in but I've a sneaky feeling that its going to happen in the new one albeit I'll put the overflow in the right place
