Hard pipe
Had the rubber by pass, it leaked around the rubber and compression fitting, try the hard pipe this time, very happy with it. Also since the rubber did a upside “u” not sure if it was air lock. The hard pipe is linear.

Well, I can' say whether this helps or not. If it does, it's likely marginal but it's drop dead easy to install, is relatively cheap, is well made and fits perfectly, and it can't hurt. LIke RiffRaff's other specific products, it's well designed and perfectly made.
