Best video on how to repair the Wilkins 720 vacuum breaker

[@SprinklerWarehouse]

Glad it was helpful!

[@PelicanNorth]

It's the little things.... I bought this kit from Sprinkler Warehouse last year, and just getting around to installing it now. The manufacturer directions don't say where to use the lubricant, so this short video showing the optional use on the O-ring really helped. Plus, the fact the spring gets pushed down underneath the lip of the breaker interior (you showed it as you seated it in) was really helpful as I was not sure if I should push it in or not. This short, concise video was perfect for a DIY project. My compliments to the presenter, the video team (with great audio!) and the graphics team.

Thank you so much!

Thank you so much for this video. My vacuum breaker was leaking and I was told it would cost $500 to rebuild it. I bought this repair kit and fixed it in a matter of minutes. My damn hero!

[@SprinklerWarehouse]

We are so glad to hear!

Thank you for your comprehensive and easy to follow instruction in Wilkins 720-A repair. The key is locking that spring inside the housing, then everything fell into place. Never got instruction on “charging” the system via the bleed cock. Excellent job, teacher.

Great video, everything clearly explained. Got my repair kit followed the super easy video and repairs completed. Took more time to gather up the tools than the repair. Thanks for help me and other with such great videos.

[@AZ_sunshine]

thank you - excellent video! You clearly explain everything. I got my repair kit and will fix my 720A tomorrow morning thanks to your great visuals and tips. thanks so much for taking the time to help others.

You're welcome!

One of the best how tos I've ever watched.

[@jaycee1373]

Short, concise and accurate. Precisely shows each step along the way, all in less than 4 minutes. I could have done the job in as few minutes as it took to watch this, except for searching for the little screws that kept falling in the lawn. NOTE: They’re nonferrous and a magnet won’t help. 😂 Thank you sir!

[@brucekemp3776]

Fabulous. Very helpful. Successful. Saved a service call $$ and the wait. Re-pressurizing demo was most helpful.

[@NovemberDelta]

Perfect internet dad video thanks for teaching me to do it myself!

[@MrJohnCrist]

Excellent video !

[@ceeshrek]

[@williamhanna2247]

Good Job

[@SprinklerWarehouse]

Thank you! We glad we could help!

[@davescellphone5376]

Everything checks out, rebuilt with new parts several times. Never seals. I'm at 35 psi. Is there a minimum pressure needed?

[@LindsayVandewater-i6z]

I can not get the spring to stay inside the housing. Is there a special way to do this?

[@tonyeoki]

Thank you!!!

[@daveh5635]

I just installed a new 720-A and forgot to pull the bonnet cover and vent out ALL the air. So>>I went back, followed your simple instructions>>Air OUT of the system! Valves working as new!!

[@SprinklerWarehouse]

Glad it helped

[@girlfromaruba]

Hi, excellent video , thank you . But I cannot remove the bonnet. It's screwed on so tight. I even tried the way you showed. What else can I do to unscrew it without breaking the pvc pipes . Please help

[@daveh5635]

I set it in the sun with Aero-Kroil applied generously to the screw thread area. 4 hours of Phoenix sun>>Screwed right out!

[@mateogrow4454]

What happens if you dont charge the system by keeping testcock open? I have an indoor unit so dont want water spraying everywhere unless i have the wife hold a bucket to catch water

[@JinthorSama]

I wish I would've watched this first lol
