sharkbites
they are pretty nice for repair fittings
I had my misgiveings too, but found them to be ok
I keep a total assortment of them in my truck in both
3/4 and 1/2 with tees too...
with all the bastard sizes and pretty colors
you see now in the stupid PEX brands,
they really can get you out of a nasty mess quickly..
I had some old POLY pipe going into a water heater that
we adapted over to copper very quickly recently
also recently , in crawl space on a Sartuday morning,.
I had a hose bib needing
to be changed out but it was run in some shitty hardware
store PEX and I was able to change it back over to copper
very quickly without having to go to Lowes and hunt
down special stupid fittings ,
Thanks to the sharkbites, I made it home before noon, which sold me on them
as long as you are sure that you have drove the fitting onto
the pipe all the way on ,
I am pretty sure it will last
about as long as the crummey Pex stuff will.
