‘Never Drain’ valve is coming to B&Q near you...

[Phil]

this new valve is a ball valve not a butterfly valve like the one in the picture, also domestic hot and cold water does not have inhibitor added, like any competent plumber knows it stops the valves from furring up and sizing.

What is the difference between the two again?

Which type is the all reliable ball type pump valve?

And how many times do you need to isolate/drain down rads? In the past 15 years I've only had to do them once (twice on a couple) for decorating. Took the opportunity to drain down and flush through. Only problem is that valve won't work with my twin entry rad valves!

It's about time you sorted out those valves
