Re: How to completely turn off sprinkler system? As others have pointed out, if its leaking, the valve must be letting water through when it shouldn't. Focus on the valve.
I would shut the water off and open up the valve. They're pretty simple inside and there may just be some debris preventing it from shutting back off completely. First remove the solenoid by just unscrewing it (grab it and turn it counter-clockwise). Then open up the, what looks like 4, screws in your case.
Should you need to replace the valve, here's another tip: If you can find the same model valves, you can usually just replace the guts without actually needing to do all the plumbing work required to replace the whole thing.
The white hex "fittings" may deceive you into thinking there's some way to unscrew them, but most are cemented to the PVC pipes below. To replace they usually saw them off and plumb new ones on. Replacement can be even more complicated if the spacing of your new valve isn't similar to the old valve.

Thanks all. to the valve it is...
The only problem, I can't turn the damned water off.
There is a small piece of the old handle still in the sprinkler shut off valve .. I tried making a tool out of aluminum to shut it off, but the tool broke ..
So I'll have to shut the water off at the main to do it.
I'll get the valve on Monday (zone 3), and look at it on Tuesday. If the cap(s) won't come off the old valve, I shall be doing some cutting on the plastic hex nuts that are indeed glued on (WTF!?)
Thanks for your help and patience. Plumbing isn't my thing.

Dry ice piled around the pipe will freeze the pipe and the water inside it. I've seen it work for copper although I'm not sure of it's effects with PVC.
Another option, albeit a wet one, is just cut the supply side while it's under pressure. Obviously water will spray everywhere but you'll be able to slip an open Sharkbite valve over the top. Once it's securely on, turn it off and finish the job. |

So,
The solenoid is leaking a little as well ... does it make sense to try and get replacement parts of just replace the entire value?

| In general it is less work to install replacement parts instead of replacing the entire valve. There may not be a big difference in cost but if you value your time and effort go with the replacement parts.
In most cases you will need to cut the PVC pipe in order to replace the entire valve which also means waiting for the glue to cure before applying pressure again.

I would try for replacement parts first.
Edit-- get enough to rebuild all of your valves. |

Yeah, I was looking at the parts list ... for the parts I need the cost is about what it would be to replace the entire valve... Unless someone knows a good place to get replacement parts for a Hunter ASV-101 anti syphon valve.

kudos:1 | If you can buy a new valve exactly like yours, do so. Then take it apart and use it for parts. You do not want to dig up and replace the entire valve unless you can't rebuild it. |

The valve itself is pretty easy to access, it's above ground. From what I could tell when I was messing with it, one side is glued, the other isn't, looks like it *might* be easy to replace....

Valves last approx 6 years, the valve warranty is about that long.
The cost for valves is usually $12-$15 ea.
I have 8 zone valves on my system, I have replaced 6 of 8, and 4 this season.
Not really hard to replace valves, shut off the water, use a PVC pipe cutting tool to slice both pipes off right below the couplers where they screw into the valve, clean off burrs on the pipes. Yes, you will now have shorter pipes. (Eventually you may have to add fittings to make the stack taller again depending on how often you replace valves.)
You will need a new valve, two male couplers to screw into the valve, a roll of teflon tape to seal the threads, PVC primer & PVC glue, the cutting tool, a small pipe wrench or strap wrench, and gloves to keep the glue and primer stuff off the hands.
Start threads on the couplers in the new valve the couplers and hand tighten to "almost tight".
Use primer on the outside of the pipes and inside the couplers.
Apply a coating of the glue to the outside of the pipe and a little inside the couplers, press the couplers/valve onto the pipes, turn the couplers about 1/4 turn with a pipe wrench to spread the glue.
Wire the valve one wire at a time to the existing wire nut connections.
Wait an hour.
Turn on the water to check for leaks.
Adjust the flow control to max , open the valve manually and throttle down the flow if needed. |

Clevere did you just eat?
I think its 30 minutes LOL
seriously why would you wait?
I have only replaced 2 valves in 10 years. rainbird brand.
I used the older impact heads and have replaced 3 in 10 years, 1 of those because someone beat it with a hammer or something like that.
PS in case you didn't know the Fing country is going to hell. |

seriously why would you wait? Because you don't want the freshly glued joint to come apart when applying pressure for the first time.
Time to cure varies greatly with the type of pvc cement used and with the product I used the last time the recommended duration was 24 hours!

Fairfield, CA | Exactly, you should wait the amount of time the glue you use recommends before pressurizing the pipes.. |

thank you for that info.
I worked as and electrician for 10 years and ran millions of miles of 4" in muddy ditches and never waited LOL
good glue makes a great bond in seconds, never thought of pressure.

Well,
I bought a new valve (entire assembly), remove the guts from the new one and placed it into the old one. Works great, no more broken seals. Even replaced the gasket on the solenoid. It works .. now time will tell if it still leaks.
18.00 total .. just as much as just the parts. and now I have a new plastic valve assembly to put a plant in.
