You'll need something like a stub wrench. If you can't find one big enough, then I'd just replace the brass ball valve, they aren't that expensive or hard to replace.

You can chisel out the pvc. Time consuming and you might end up replacing the ball valves if you damage the threads. Might be best to do the above.

Yup, replace the ball valve. OR - melt the PVC with your torch, and pry it out.

I melt 'em out myself. This way I have the torch handy to lite up those fireants too.

You ever notice that when you torch an ant they really pick up speed then suddenly - stop?

Two ways to do this, we fix these all the time.

Heat up a screwdriver with a torch and melt through the remaining male adapter in two places about 1/4" apart perpendicular to the threads. Then tap the piece out with a small screwdriver and the remaining piece of the male adapter can be removed easily.

The other way is to use a hacksaw blade (off the saw) and cut two slits the same way approx. 1/4" apart and knock out the piece.

I have done the top version dozens of times and it works perfect!


Make sure you get paid for you unique on the job experience.

they make a tool for this, it is called a stub wrench a must have, they come 1/4 1/2 3/4 1" ridged makes a good one. They can be found at the Home depot, Loews, a good hardware store or your plumbing supply house. Buy one and keep it in your service truck
