Thanks for trhe sarcastic remark,
It is the same site which i got straight away.
I was trying to find one identical to the the one i have, that is why i asked the question in the first place.
I have a baxi solo boiler, gravity fed pump and vented system.
The installer did everything and it was working ok
And backfill is when you put a hose pipe on to the drain cock near the boiler and fill from the bottom hopefully pushing the air through the radiators and up through the cold...
Can anyone tell me what this does?
Satchwell control actuator type sm for use with 3 wire control and it is conected to a hot water pipe in one of my cupboards but the wires have been cut.
I have just had a new boiler fitted to my 1 pipe system.
I have back filled with a hose pipe, blead the system etc.
The first night everything was ok, the following morning when my heating came on 1 radiator possibly the last one was cold.
I have tried bleeding the system and quite a lot...
