Refilling old floor standing boiler

[dunny]

I have had to remove some radiators to hack off the plasterwork as the damp course guys will be injecting the downstairs walls later this week.

The boiler is an old floor standing oil powered one (electrolux i think) and has a total of 4 water pipes connected, all in what looks like 22mm copper. I cant see a direct water feed so i assume one of the pipes will come from the header tank in the loft.

To drain I closed the valve at the pump and then each of the valves at the radiators and have now removed the 5 downstairs radiators.

When it comes to filling the system again is it just a case of connecting it all up and bleeding each radiator before switching system on and bleeding again?

I will be having the whole system changed at some point but not in the immediate future. Any help wold be appreciated.

Thanks

Thats what you need to try first.

It may be fine or could create air locks.

It's been a bit of a nightmare since the valves are mostly leaking and need replacing so with the radiators off the wall the leaking has been hard to control. Not convinced I have properly drained the system down and it may still be filling up from somewhere. I assumed that with only 4 pipes coming in to the boiler and no direct cod water feed that the correct isolation valve would be the one upstream of the pump?

The only pipe to isolate is the cold feed to the F&E tank!

Thanks.

I reached that conclusion earlier but as there didnt appear to be one I went or the only one I could find.

I am wondering now whether it's in the loft.
