Have a problem with my father in laws 105 HE Inst ( i know go on, get over the laughing fit) Anyway, loosing presure, or is it ?
The gauge is reading 0 so top it upto 1.5 and away it goes. 10 mins later 0 again. I noticed their was a slight drip for the relief valve so i twisted it till it let water pass then let go to dislodge any ****e that may have been preventing a seal.
Fired up the boiler for another 10 mins. Noticed it was still dripping so the valve was replaced. The pressure issue is still the same BUT i have noticed the boiler still runs ok and heats the rads ok even with no pressure.
Also, if i top up to 1.5 bar, once the boiler fires up and runs for 10 mins or so the relief valve dumps a load of water out? Could this be simply a faulty gauge ? and its reading low so i am over filling the system and the valve is dumping excess pressure ?
