Hey there!
We are almost neighbors
I used to use those Grabber brand fittings with Qest but they got hard to find for awhile. My method was definitely not an approved method but thankfully it has held for close to a week. We are so dang far from a Lowes or similar place that when we ran into this situation we couldn't make it to the store and had already cut the pipe
That figures don't it LOL!
Speaking of South Holston I remember several years ago I was called to check a vhf radio in a yacht of sorts, big ole boat anyway
The owner wanted to go out in the lake a ways to verify my repair and I agreed. That was the first time I had ever been so far out in the water where I couldn't see any land and I was nervous as a cat on a hot tin roof
Long story short the radio worked fine and I was very happy it did... in case I had heart failure!
