You were overly sensitive to what the tailpiece would have looked like, and I would not have any compuction against using it. Saddles are bad for pressure pipes and major drain connections, not R/O drains. It appears you are describing something like a swimming pool pipe saddle, and THAT I would not use under your sink.
Thanks, Hj.
I doubt the tailpiece he showed me was for a swimming pool. It was on the rack amongst plumbing for residential bathrooms and kitchens. It was pretty muvh as you described, and photos I found online.
It wasn't so much the uglyness ans it was the size. The whole thing stuck out about 6-7" from the tailpiece, and things are pretty tight under there. Somebody ought to sell these systems sized for bathrooms.
I share your assessment about the saddles. For one thing, a supply tap is going to have 40-50 psi at the joint, wheres a drain has zero.
Again, thanks for the help. I need someone to talk to about these things, rahter than stumbling around. I do appreciate it. It's a great forum, and I will bookmark it.
