not too sure . son's not long moved in , house was virtually empty for more than 3 years , so I reckon it's 5 - 10 yrs old - maybe more . to be honest I suspect the bellbox but want to make sure .
Hi all , my son has the above alarm which has just developed a constant chirping sound , like a smoke alarm but without pause . I assumed it was the control battery but strangely when he turns off the mains the noise stops .
He's disconnected both the mains and the back up battery but the alarm...
thanks Mick,
yes the pressure is set at 2 but I did lower it to about 1.5 , this gradually rose to just over 2 as the heating was on . when it goes any higher I drain some water back down to 1.5 . I never had this problem before the valve went faulty
hi , since replacing the relief valve my boiler has become noisy , it sounds like a pulsing hum from the pump . it works ok but the pressure rises from 2 to 3 ( I think that's normal but not sure ). any advice gratefully received thanks.
