I need a wee bit of help.

I have basically tee'd off my Central Heating circuit for a radiator. I would say that the run is around 3 metres long (1 Supply, 1 Return). At the moment, I dont have a radiator to put on and wont for 4 weeks. I need to get the floor down NOW!!

I have capped off the Supply and Return at the wall, using Compression Stops.

My question is this. If I turn on the heating and bleed all the radiators is this new run fully pressurised?? I want to know if the new joints have been successful so that I can lay the floor. There doesn't appear to be any water coming out of them, but maybe there isnt enough pressure?

I now have the boiler running and have bled all the rads and set the boiler to 1.5 bar. It is slowly gaining pressure whilst the boiler is running and with the fill-loop closed and we turned the boiler off when it approached 2 bar as I was worried!! Is this right? It is a Combi boiler BTW.

Do I need to bleed these capped stubs?

Ta in advance........
