CH Draining Problem
Following on from my problem yesterday with the rad Bleed Screw
failing I decided to do what I had intended doing soon anyway . I switched the boiler off ( and power too) and shut the cold water inlet .I then opened the drain valve and the rad valves and bleed screws as well. This the first time I have drained the system and I noticed that the valve only turns about one half turn whereas I'd have expected it to turn more . The valve was fitted by the guy who fitted the boiler about 18 months ago and it can be seen here . http://img.photobucket.com/albums/v4...n/IMGP0108.jpg http://img.photobucket.com/albums/v4...n/IMGP0109.jpg I removed the handle to make it easier to see. The system is the two 22mm pipes from boiler to hall and 10/12mm from that point on via a manifold . The new rad in the hall is not connected up yet so I opened up the old valves ( as they need to be removed ) and there was water coming out so I continued draining them until they stopped running. I then cut in to a 10mm pipe leading to another rad that I was removing and water came out from the boiler side of that pipe and showed little sign of stopping so I closed the pipe with molegrips . I've decided to leave it for a while . Is there something I am missing here .All the rads are drained so the problem appears to be between the hall and the drain . Is it possible the drain valve is only opening partially and I just need to leave it longer ...but it has been open all night !!! The cold inlet is definitely closed properly . Any ideas ? -------------- Any posting using my name and/or e-mail address but other than by newsindividual.net is not being posted by me and should be disregarded .
