When running the hot tap the boiler makes a loud banging noise and the presseure dial goes upto 3 bar. Burner lights up till temperature shows 99 then it goes out and reignites again. Flow pipe gets hot when hot tap is running?
I thought it was the diverer valve diaphragm split thus sending hot water into the central heating causing the pressure rise and hot flow pipe.
Any advice much appreciated.
