It really is an outstanding valve, very easy to turn and fine tune. Not quite a gate, but prety good. I have a 2" one on the inlet of my Dart and a 1 1/2" on the out. I am adding a new Barr skimmer and ordered some plumbing and bulheads from Savco and decided to try one of their true union valves. They are very cheap, I think it was like $13 for a 1" compared to $22 for the Georg Fischer. I'll let you know.:mixed:
