[RE-wrenches] Water system with Grundfos SQFlex

[Ray Walters]

Sorry Brad,

It's been a long time since I did well work, and now, I can't find a 
supplier of the fittings.  The pics I sent earlier were just 
representative, but not exactly what I used in the past. What I had used 
were bronze compression fittings similar to liquid tite conduit male 
adapters.  I have no idea who made them, or where I got them from. The 
closest I can find now are for poly gas line, and they're over $100/ 
fitting at Grainger.

Main product photo I use PEX and Shark bite fittings for any plumbing 
I'm doing now.  Never had a leak, super fast, and reversible.
