Replace ball valve and anti siphon valve copper

[gerry]

Hi I need to replace the anti siphon brass valve and the ball valve. Any suggestions on best way to do this? I'm not sure which joints I should unsweat and steps to put it back together.

1. Check pressure to see if you need pressure reducing valve.
2. you sure you need to replace the LHBV ?
if not, I'd suggest hacking off just the anti-siphon valve, adding a dedicated LHBV as required to serve the sprinkler then you are done.
A good plumber with a pro-press can rebuild the whole thing in 20 minutes.

Thank you. I'll check the pressure. The ball valve doesn't completely shut off the water and I already tried tightening it. So I thought I might as well replace it while I'm replacing the leaking anti siphon valve.

That anti siphon valve is for your is for your irrigation I'm guessing, watts makes a couple different styles Pvb or rpz depending on the higher of your highest sprinkler head
