Hi
Due to noisy radiators and some noisy pipework. I decided to drain down my CH sytem today and refill with inhibtor.
Drained using a drain valve from downstairs rad. due to stopcock not being the best. All seemed to go well and filled the system back up.
Downstairs rads all drained of air but not enough pressure to force the air out on the upstairs rads?
Problems encountered when putting CH back on: -
No water in the pump. Pump seems to be pumping.
Therefore no water being circulated and no rads coming back on.
The boiler is making a hissing noise (a bit like a kettle being boiled) when the heating is swtiched on.
Any ideas?
