How to Replace a Sprinkler Valve

[@dfmayes]

Manufacturer of my valve, Hunter, said to use Teflon tape on the threaded connection. I would also recommend dry fitting the pvc and marking the full insertion position on the pipe with a marker. That way you can tell if you have pushed the pipe down fully.

[@stealthkitchen4375]

I cant seem to fully dry fit my pipes and couplers any suggestions? Thx

[@jfens786]

I put Teflon tape and it’s still leaking even though I torqued it. Maybe I torqued it too high?

[@pmb5889]

Use teflon tape on the threads. Also use PVC primer before applying glue.

[@IAMHe777]

Yes sir bought printer today in a package deal w cement for 5$

[@LogicofChaos7871]

Take it to the next level and use pipe dope, tape, then dope again for threaded fittings. Also use a fine sandpaper or emory cloth to take the finish off the pipe, then primer, then cement. No leaks...

[@JohnnyC10071959]

@@LogicofChaos7871 Yep. I have done a thousand of them exactly described. I have also been told that pipe dope and tape are not needed with PVC and I know pros who swear by that claim. They say they have done hundreds/thousands of joints over decades and no leaks w/o dope or tape. I sleep better with the dope/tape/dope method. I have never known anyone who joined PVC w/o primer.

[@LogicofChaos7871]

@@JohnnyC10071959 I have had one leak in 14 years. It was on what should have been a mirror weld. No mirror....pinhole leak

[@lilAF626]

@@JohnnyC10071959 it’s always better to do the most especially if you’re in the landscaping business and fix a lot of these like myself I do all these extra steps so the clients are sure about what I’m doing and they won’t be saying anything like “oh you only cut the pipe and glue the other one on and you’re charging me this much” but if your doing it at your own home or a buddys all those steps aren’t required

[@JustMe-gf6gq]

Just a heads up, you should apply PVC primer, let it sit for a few minutes before applying the glue. The primer softens the PVC so you get a solid perfect joint. And you should apply glue to both sodes of the joint....ie, fitting and pipe Also, you should be using Teflon tape on the plastic threads. Maybe not required, but good practice. I am sure for the little water pressure that runs to our homes it should be fine the way you did it. But, regardless you should know the right way, especially if you are making a DIY video. As a 20yr Union Pipefitter, I have had lots of practice.

[@chieflouie2821]

Thanks. I use primer as my pipe/fitting depth guide.

I would also recommend the teflon tape, just to be on the safe side. If you have a leak in the threads, will need to cut the pipes and start over..

[@carlenekline6506]

Would have been nice to see the addition of the 3/4 to 3/4 female unions on the pipe coming from the ground. Also, always use primer before the glue, as it makes a better seal and teflon tape on the threads for a better seal. Really liked removing the cylinoid first before removing the old valve as I'm not too nifty with the wires.

Thanks for the demo and info, I was about to hire a contractor, but after watching your video, I think I can do this! lol

Oh BTW, did you replace all 3 valves or just one? Do I need to replace all 3 for compatibility?

[@thehonestman26]

Couple things I noticed. First, I can buy those at my local Home Depot, and they have pretty good ratings. I bought a couple to replace my brass ones instead of rebuilding them. Secondly, they recommend you somehow attach the pvc to the inlet side and try it first to check for leaks before assembling the outlet side. I haven't figured out how to do that part yet. Anybody have suggestions, that would be great. Other than that, thank you for the video. It helped me out, especially using the clamp.

Good video you saved me some money. Thank you!

[@vt8618]

Your Video was excellent. I also took advice of "Just me " in adding a teflon tape to the groves before threading the valve. I also used primer. This is the first time I attempted to replace the valve and I just completed it. Here are some f the issues I face as a novice first time installer. You have to deep deep and a big circumference if you want to use the pipe cutter to cut the pipes coming out of the ground. I was not able to cut it properly. so I had to use my drummer tool, to make it even and sand the top. So that no debris go into the pipe I stuffed it with cloth which I removed after all the sanding, cutting, planing was done. So being new at this, I had to do extra work to make smooth and level. Also I might have used too much glue, i don't know what is too much but my glue application was dripping slightly. I also found the old pipe coming out of the ground had glue drippings, hence I had to sand it , with a sand paper as well as my dremel kit. It took me 2 hours more than it would have taken a professional. But I must say, this excellent video gave me the courage to complete the installation of the new valve. That valve was I believe defective , because any time I opened any zone , that defective zone always went on and the sprinklers came alive, I just turned on a few zones to check if the problem was solved and Eureka it was solved, Installation successful. I want to let the readers know, this is not an easy task.... not at least the very first time. I had all the tools and I am also an engineer by profession. I have 40 Valves in my property, thank you for saving me a ton of money.

[@ConfiscatedZyra]

piano wires are nice for the digging part. u don't have to dig as deep and no awkward positions while cutting

[@Halfwheelhell]

without reading the instructions on the pvc glue, I recall quarter turns on fittings to make certain the glue contacts fully. I probably would have spun those unions, and sanded them a bit. maybe that's a bit more belt and suspenders... thanks for posting the video!

[@Sagemeister007]

Thanks for this tutorial video. This helped out a lot!

[@coffeeabuse]

2:39 Before you unscrew the solenoids, you may want to mark them with something like #1 , #2, and #3 and restore them later so afterward the signal from the valve timer still goes to the correct valve.

[@DoItYourselfDad]

Very good point!

[@tk3828]

Great video. Noticed the step of gluing the fittings to the cut ends of the pipes were not shown in the video. Also didn’t see the tape to the threads before connecting! Still very helpful though, thank you

[@xworkerbee]

Just a note to wrap the male threads of the PVC adapters with teflon tape or a bit of clear silicone. Without it those threaded connections are going to leak.

[@stephenkennedy8767]

This is excellent! I have to do just one valve but this will save me a lot of money!

[@DoItYourselfDad]

[@garyhammond5267]

A lot easier to replace valves if you put a union in the "out" side when valves are originally installed

[@marvinjones9390]

Thank you. Very clear and easy to follow. One question: When connecting the wires, how do you know which of the wires on the new valve is the control wire and which is the ground? It looks like they both have the same white stripe.

[@AgentOffice]

Doesn't matter on AC valves

[@brotito9126]

Kind of makes you a little bit worried though. Especially if it doesn’t work the next day. I’m gonna let my glue cure and see how it works the next day after about 24 hours.

[@byronrace]

If you're tired of cutting and gluing and extending sprinkler riser pipe over and over again, look into sharkbite fittings. Google UIP134. Screw that part into the sprinkler valve threaded connections, and just press it down onto the PVC pipe and you're done. If the valve goes bad or needs a vinegar soak, slip two sharkbite disconnect tools under the fittings, and lift. Pop, off comes the valve so you can take it apart and vinegar soak it to remove hard water deposits. No glue. No waiting.

[@DoItYourselfDad]

Those are awesome! I'll definitely look into those next time!

[@byronrace]

Just don't forget to turn the water off and bleed off the pressure before popping them off. I added stainless ball valves on the input side so I could shut off the water prior to removing the valve. They're about $10 on ebay. I have to service these sprinkler valves annually with a vinegar soak due to hard water deposits. The sharkbite fittings and shut-off valve cut hours off the project time. I've inserted and removed the same PVC stubs 4 times now; no appreciable wear and no leaks. They really work well.

[@winfidel]

I use an adapter from Home Depot, etc, that's all PVC, and much cheaper (www.homedepot.com/p/Homewerks-Worldwide-3-4-in-PVC-Compression-x-Male-Repair-Adapter-511-46-34-34H/206682798). Push on to PVC pipe end, screw other end into valve, and hand tighten to secure to pipe. Or, even easier and cheaper, although I've never used them yet, are Orbit's PVC Lock system that require no glue, can be rotated on the pipe, and even removed with a removal tool (www.homedepot.com/p/Orbit-3-4-in-PVC-Lock-x-3-4-in-MPT-Adapter-37778/203266655).

[@byronrace]

I love the concept of that PVC compression adapter. How long have you had one in service outside in the sun? I find it challenging enough to keep PVC pipe alive here in Gilroy, CA in the intense heat and sun. If you don't paint your pipe, it will only last about 3 years before it becomes so brittle it'll snap off when you actuate a ball valve. I'll try this adapter on one of my sprinkler heads; very cheap!

[@winfidel]

I've had mine for more than 3 years - maybe 5 or more, in Pleasant Hill, which is probably hotter. But it's in the shade.

[@jacksmith7082]

[@troyseagondollar4565]

Here's some tips: know the width of the connections before buying a new valve - some are up to an inch off. Use an in-line connector that will allow you to remove the old valve without having to cut the pipe - orbit has a product or you can use the PVC sharkbite like products. When you buy a valve purchase a diaphragm kit - 99% of the time the diaphragm is the problem and it usually goes out years after the company changed designs so you wont be able to find it (case in point watermaster was bought by orbit thus you can't easily find the diaphragms)

[@michaelsinitsky60]

[@TheParkLarkPrivate]

A key omission from this otherwise excellent DIY video was to insure the flow direction of the water from supply to sprinkler heads in the lawn/garden. Flow is marked by arrow typically on the underside of the valve. Installing the valve incorrectly that is in opposite flow of the water will result in water flushing constantly from the anti siphon valve cap.

[@CarlosGarcia-ls4hn]

You need to make sure which is the input and output for the sprinkler valve, meaning that you need to know which of the two pipes the water comes out of the ground from.

When you put the preassembled valve into the pipe openings in the ground, you can't twist it, so wouldn't it be better to add glue on the outside of thje 6" pipe segments to ensure you have enough glue and a good enough seal as an insurance policy?

Longevity of the joint, resistance to intrusion (e.g., tree roots), etc. are of primary importance. If you are looking a CPVC for supply lines, now you have to rethink for pressure strength. Still, not many lines are running sustained 1500 + PSI. The pipe itself probably isn't rated that high (at least for sustained stress -- and what schedule pipe matters also). For a "relatively" pressurized sprinkler line, I think below grade I'd err on the side of two-stage. For above grade, I wouldn't be thinking about how it looks either! Also, 1/2 turn to distribute the glue, that's it. To get the strongest join, you should insert, then turn... not corkscrew in.

Exactly. Teflon and purple primer are a must.

Why are your valves above ground and mine below ground? Installer's choice? Or some design reason?

[@DoItYourselfDad]

Valves need to be a minimum elevation above the highest head, and I don’t live in freeze zone.

What causes the anti siphon to leak out water? Everytime the sprinklers shut of the anti siphon leaks out water.

[@alexle7964]

Got it done just like in the video but every time I turn on and or off is leaking water? Any ideas?

I hear air coming out of the backflow when valve is off. Is that normal?

[@fvang4751]

The electricity was not brought up. I assume the electricity was turned off to attach the wires???

Did all that however when l turn on it doesn't run .When I turn to off setting it runs and auto it runs and does not stop What can I do to fix this
