Rad Drain C*ck question & Plumbing supplies recommendation

Can't answer your question but the engineer that did our heating put some very neat little drain c~cks in that were combined with the radiator valves - a bit like but not exactly like these http://www.uk-plumbing.com/pegler-terrier-cp-manual-radiator-valve-lockshield-with-drain-off-angled-8mm-p-1157.html. The radiators do have TRV's on them so its possible the drains are on the other end of the radiator (would have to be at home to check). Just makes the pipework look neater as you don't have a traditional drain halfway up a pipe. Some of our radiators are in fairly tight spaces due to low window sills and it means you can have the radiator tighter to the floor with virtually no vertical pipe. I guess however there is a cost implication!

I think I just got a type A from Screwfic, it "seemed" to look more heavy duty. I also reme,ber something about the finish, as type A was heavy pattened and type B was light. Don't actually know the difference though :rolleyes:

Agree with your comments, WestonDave.:T I will also add that having a drainc*ck/rad valve combination means that depending on the position of the valve, you can drain down the heating system OR just the radiator - which is very handy if you need to put in some additive in a closed (combi boiler type) system and need to "make room" for it .
Price wise, only talking a couple of quid extra for an integral drainc*ck
