no drain point

[zutman]

I have a leaking rad valve but there is only one drain point just above the boiler on the return pipe but its does not work there are no other drain points on any of the upstaire or down stairs rads how am i going to change the valve on the upstairs bathroom rad oh its a conventional system,

hire a freeze kit

Or isolate the small feeder tank in the loft pick any rad below the one you want to work on turn off its valves , drain it off by releasing it from the radiator.

If all goes well you should now be able to fit a hose to one of the valves and drain down.

Be warned read previous posts about rads not heating refilling can be much more difficult that getting the water out.

what i normally do when face with this type of thing is make a temporary drain off by using a self cutting washing machine valve (about 7.00 for b+q)

Blooming handy they are for this just remember to install a proper drain off when you are done.

How do you make sure the little circle of copper comes out of the system?

Never lost one mate

They are always clinging on like a goody when you take the tap apart

Yeah - but if you're a bit unlucky, that little disk is just the right size to jam the pump or block something in the boiler!
