In the middle of a bit of a DIY disaster and will probably have to call in the professionals tomorrow. I needed to remove a radiator as part of the downstairs cloakroom refurb project (I posted a while back about burying pipes - many thanks for replies) - Its 8mm microbore with a seized radiator valve. Anyway I drained down system by loosening the valve and managed to fit compression end stops to the two pipes and remove the rad.
Its a vented system with old style boiler and hot water tank.
I refilled checking no leaks on my end stops. I found the ground floor rads didn't need much bleeding but the upstairs ones did. Unfortunately I couldn't get at a couple of the rads, behind a mountain of junk.
I restarted the timer etc and boiler. After a few minutes the boiler tripped out. The pump continued to run but with a grinding noise. I reset the boiler but it tripped again fairly quickly. I switched off the CH and Water on the timer but the pump comntinued to rumble away. After 5 minutes I switched off the power supply to the timer which stopped the pump.
Do you think this is all due to there still being air in the system...and if I bleed the 2 rads I missed first time round, do you think that will solve the problem?... or is it on the phone to a plumber tomorrow!
