Watts anti-syphon valve needs replacing - with what?
Hi, outside of replacing sprinkler heads and broken pipes, I'm a newbie at irrigation.
I've a small garden sprinkler system which has a Watts 1" 800M4QT anti-syphon valve which suddenly failed after 15 years - continually leaking a large volume of water through the bonnet. I tried resetting the internal parts but it still fails. I realize there are service kits but this valve is old and is in bad shape. I'd like to replace it. I see there are other anti-syphon valves out there that are considerably cheaper than the Watts - and my budget is VERY tight. For example, there's a 1" manual brass valve by Champion or Orbit - can I just swap this into my system instead of the Watts? How do I know what my system needs in terms of an anti-syphon device?
