Way better!

Kept having problems with my 5 gallon tank leaking down. Fixed a couple of small leaks. Still leaking. Put a brand new Viair check valve in.....tank leaked down faster! Bought this quality (and huge) check valve.....now it goes for about a week before pressure drops from 200 psi to 180 psi.....worth the extra cost!
