Help replacing ball valve


I am replacing a ball valve for my sprinkler vacuum breaker. It is threaded on both ends but one end is leaking. Is there a way to unscrew the valve without cutting the pipe or unsoldering a joint? It is threaded on both end but each end spins a different way to tighten.

Help replacing ball valve


The valve on the left is what I need to take off and add Teflon tape. Is there a way to just unscrew it, re tape it, and screw it back on?

Never got an answer! Same job different question. I assume I have to either cut pipe or desolder joint and remove threaded fitting. Re-tape and go from there was just hoping there was an easier way.

To the left of the ball valve is a coupling. Take two wrenches and take the coupling apart. This will allow you to unscrew the ball valve from the breaker.
I don't know if they sell just the ball valve but you may find one at a large plumbing supply and/or sprinkler supply company....or on-line.

If it was me.....I would separate both couplings next to each ball valve and replace the entire vacuum breaker. The old one should have a model number on it.
You can always look on e-Bay.

Good luck

Break the couplings with wrenches on the large nut and the male side of the coupling.

If you break the unions apart, you can remove the vacuum breaker and valves. then you can do whatever you want to it. Thats the beauty of unions- they allow you to do what you're asking.
