The union in the photograph doesnâ??t look terrible to me. Iâ??ve certainly
successfully worked with worse. If only to buy you some time, it canâ??t hurt
to wrap a couple of extra turns of teflon tape around the new fitting - or
goober it up with pipe dope - and see if it works.
That isnâ??t to say that a re-plumb isnâ??t in your future. The clogged pipe
looks pretty scary. I havenâ??t worked much with PEX, but have watched
plumbers using it and am pretty impressed. None of the pros seem to use
crimpers for their connections, and they tell me they donâ??t trust crimped
connections. They use something like this:

There are manual versions of this for sale, but I am sure this is the way to
go if you are doing a fair amount of work.
I have also been told by professionals that Shark Bite fittings are really
good. They are expensive if you are doing a lot of work, but a good way
connecting PEX to other forms of pipe.
