Forum Title: How to instal check or ball valve on outdoor copper pic
Hello, plumbing newbie here. want to know if this is something I can do myself or need welding other specialized tools. Fairly handy weekend warrior but never worked with copper tubes. My issues (see pic) Our sprinkler system is supplied from a branch of our main water supply. Our home inspection noted that there is no check valve to our sprinkler system. I would like to either install a check valve( if that will be sufficient) or a ball valve. We do not use the sprinkler system and I dont want to spend a whole bunch of money installing backflow prevention. I was wondering if this would be something I could do with a compression fitting or is it above my paygrade and would need welding. Any suggestions would be helpful. Also, separately, I was wondering if sprinkler valves with built-in anti-siphon capabilities do not need a separate backflow prevention system. Thanks for your time!
