OK got the loop sorted but having issues with the heating return. Everytime I take the nut off to fit the loop it pours out with water. Is this normal. The cold water went on fine.

That is what the valve is for!
Turn the isolation valve to OFF.

I'm talking about when I take the filling loop off. After I have filled the system it pours out.

Looks like the valve from the heating return isnt working !!!!!!.

What on earth are you trying to do, your boiler will already have the valves connected, or are you actually fitting the boiler ?

Hi southcoast.

I was trying to add a little water to the system to get the pressure up. When trying to fit the filling loop I turned off the cold water valve and the heating return valve on the boiler and started to unscrew the bolts connected to these pipes. Cold water was fine but when unscrewing heating return bolt it pored out even with the valve in the off position. I have had to leave the filling loop on(which i didn't want to do)as the heating return is not isolated and every time I fill the system up it pours out.

The heating return valve must be knackered on the boiler me thinks

So to recap.

Your filling loop was missing, so you bought a filling loop that had isolation valves attached to each end.

You eventually fitted this loop including the new isolation valves when you only needed to fit the actual filling loop.

Now you say that one of the new isolation valves is not working.

Post pictures of your filling loop showing this isolation valve that is not working.

On the image the pipe on the far right(behind the filling loop, sorry couldn't get a decent picture) has a valve on it. This doesn't seem to be working.[/img]

Doh!

The heating return valve on the boiler is normally open, like all of the other isolation valves on the boiler wall plate. These valves are used to isolate the boiler from the system pipework e.g. to allow the boiler to be removed from the wall without totally draining down the whole system.

If both filling loop valves are closed, the filling loop (the flexible braided metal part) can be removed using the hand tightened couplings at the end of the of the loop with no water loss apart from the contents of the filling loop. You do not use a wrench to remove the filling loop and it's isolation valves together!
