Evening all,
I've just changed a Keston system boiler for a regular Worcestor with a pump. The customer had bought the boiler mistakenly thinking it was a like for like swap. I've added the pump and everything seemed fine but a week later he's complaining about air in the system and the F&E tank overflowing. I'd replaced the float valve and probably didn't bend the arm enough as there wasn't a lot of room for a 18 rad system. I've adjusted the arm further. I suspect the air is being sucked in through the vent. It's an S plan in a three storey house with the boiler and cylinder in a cupboard on the middle floor. The pump is on the flow pipe. The rads are all knackered and he didn't want a powerflush as he didn't think they would stand it. I agreed and tried to flush as much of the sludge out with detergent. I've turned the pump down. Has anyone any ideas what I can do? From distant memory I seem to think a 'wet vent' might be the answer but I can't remember how to do one. Any advice appreciated.
