Where would I find my cleanout pipe?
Eddie, this would be something you would want to contact your sewer department. Depending on the age of your system it may be geo tagged. Some people see them sticking up above the ground a little bit. Sometimes even asking neighbors where theirs are can give you an indication where to look. To my knowledge they are all going to be accessible from outdoors.
Do you have a link on the video you did to take the seats out
I don't think I ever did that video. I would have to search the videos.
Thank you! This was super helpful
Awesome tutorial. Thank you.
Homeowner here. Curious what you think might be wrong here. When I turn on the water too the system the Wilkins 720 PVB seals and the mainline fills. When I activate zone 1 the PVB leaks and nothing comes out of any of the heads. What might you recommend? Thank you!
I am guessing when you activate zone 1 and the PVB leaks, it means it is dumping all the water that would be going to the zone. Is that correct? Does this do it on any other zone? It sounds like you are losing too much pressure after the PVB. Either there are too many heads on the zone or there is a break between the valve and the heads. For some reason too much water going out and not enough pressure to sustain the float of the PVB to keep it sealed. Call me if you need to and we can talk. Sean, 801-355-6736
What an educational video. Thorough and succinct explanation. Thank you
Thank you. Now I know how to open and close my test cock valves.
You should do all youtube videos. Great explanation.
Excellent information! This is the fourth video on this regulator that I watched and is the only one to explain what I was doing wrong. Problem solved.
Just noticed a small drip coming out of the horizontal test cock. Is there a remedy for this or is this normal? Thank you!
No. It is not normal. Make sure the screw slot is turned straight across the valve. Every quarter turn is open /close. If it is then it might be time to change the test cock or you can go buy a 1/4" brass plug, teflon it and put in if it is a female ended test cock. If it has a male end then buy a cap. Or you can replace the test cock. I am guessing your assembly is a 1" or smaller line size so that means you need a 1/8" male fitting (that goes into the body of the assembly) by a 1/4" female, or by a new one. Here is the link to the test cocks on our site. backflow-supply.com/search?q=test+cocks&options%5Bprefix%5D=last
@@backflowsupplyslcut9394 I thought I had it stopped but now it's not just dripping but more like spraying out where the plastic plug fits. I tried to teflon tape the plug until I can order something but that didn't work either. How do I know which size plug to order and does it need to be lead free? Thank you!
@@robertkoellisch470 Is the screw slot going in the direction of the flow or across the test cock. It should be going across the test cock. If you need a plug in it for now and it is a female test cock you need a 1/4" male plug. If it is a male flare fitting you need a 1/4" flare fitting (cap)with an o-ring on it to stop it.
I have the one on the left but when I remove the bonnet it’s a black piece with only 1 long piece it’s so hard to even remove I can’t get it to budge. Any advice ?
I wonder if you have a different model. Both of these are the Wilkins 720A. I wonder if you have the Wattts 800M4 PVB? czcams.com/video/sqYsxJJk8m4/video.html Watch this and see if it helps. You are welcome to send me pictures to sean@backflow-supply.com or call at 801-355-6736
Thanks, I had reduced pressure on all zones and my 800M4 was squealing when running. I took everything apart and cleaned it and ensured there were no cracks and or any damage. The difference is my float has a center tube with an internal spring the fits up into the bonnet center spring area. The pressure has returned minus the squeal but I now have a small leak and was going to replace everything inside our 20-year-old Watt 800M4 R regulator but I am not able to find a kit with the same float. Help and thanks again.
I am not sure which size you have. 1" is most common, but here is a link to the parts for the 3/4" backflow-supply.com/collections/all?filter.p.m.custom.watts_models=800M4&filter.p.m.custom.sizes=3%2F4%22 and the 1" backflow-supply.com/collections/all?filter.p.m.custom.watts_models=800M4&filter.p.m.custom.sizes=3%2F4%22 just depends on if you want just that part or a complete kit. Call me if you have questions Sean 801-355-6736
i good looking
What if it's not leaking water but the pressure test failed to submit to tne County?
I am not sure I am following your question. You had the assembly tested and it failed? That is a possibility. The air inlet could have opened below the required 1.0 or the check valve in the bottom could have leaked or not held at 1.0 or above. This would require perhaps a simple cleaning or rubber parts or complete parts. Hard to determine without seeing the components and knowing what the issue was in the first place. You are welcome to call me at 801-355-6736 and ask for Sean or email me at sean@backflow-supply.com
@@backflowsupplyslcut9394 Yes I had the pressure tested and it failed. Otherwise, its functioning fine zero issues.
@@shanew7361 Maybe I need to clarify. Did someone come out to do a specific backflow test, using a gauge and they hooked a hose up to it? Did they leave a copy of the report?
@backflowsupplyslcut9394 Correct, and no report was given. I'm having a different plumbing company retest it.
@@shanew7361 Make sure you ask them to explain why and how it failed so you know what you need to fix it.

i got it
I’ve learned a lot from this video. And now I know that the guy who installed mine didn’t know what he was doing. So now I will have to have it re-installed. I wish there was a way I could show you a picture of mine.
You can email it to me at sean@backflow-supply.com
Any thoughts?
it is not uncommon for a new install to leak. There could have been debris, such as rocks, sand or rust in your pipes that when turned on got stuck in the #1 check. I am assuming this is on a lawn sprinkler system. If so turn a zone on that will get more flow going through the heads than what is coming out of the relief valve. If it stops leaking out of the relief valve when the zones are running the problem is in the #1 check assembly. If it doesn't it is in the relief valve. Almost always it is in the #1 check assembly. If you determine it is in the #1 check take it apart and look for rocks, rust, even teflon tape or pipe dope. Clean it out, flush the line for a minute or so with the part out and the cover off then reassemble and try again. If you still need assistance you are welcome to call me at 801-355-6736.
I have a brand new backflow just out of the box that’s leaking just like that
I installed a new RP4A, bled the input and I'm sure its installed in the right direction but as soon as I turn the water on it starts gushing out the bottom. The unit is brand new so what might be the problem.
Maybe you have resolved this already. But the first thing to do is to get a flow going through the backflow assembly greater than what is coming out the relief valve. I am assuming this is going to a lawn sprinkler system. Even though it is dumping water turn a zone on that will get the required flow of water and observe if it stops dumping. If it does you know there is an issue in the first check valve. If it doesn't it is an issue with the relief valve. It is not uncommon on a new install for debris in the line, rocks, rust or other debris gets flushed into the first check. Take it apart and see if that is your issue, inspect the rubber and the seat to make sure they didn't get damaged and put it back together and turn it on again. Hopefully it doesn't dump again. But sometimes it will and it could still be more debris in the line. I have seen a few issues with the relief valve in the last year in brand new units. So far I have not been able to determine the cause but have provided those that brought the unit from me with a new relief valve and it has solved the issue. This is rare. You are welcome to call me at 801-355-6736 if needed. Ask for Sean.
I wish you hosted all how to videos on CZcams. Outstanding job!
Thank you very much.
Is it an optical illusion or does the apparatus on the right look bigger than the one on the left? I don't see any size specification on the 720-A that I'm looking at here at home.
If you are referring to the two assemblies in front of me in the video, the old one is a 1" and the new one (the left) is 3/4". But the bodies are the same for 1/2", 3/4" and 1". You will be able to find the size raised in the brass on each of the ball valves. It will be marked as a 3/4" or 1" most likely.
@@backflowsupplyslcut9394 Thank you, I will take a 2nd look.
Great video. Very informative. Thank you!
Excellent video, very informative! Thank you
Correction. Yes you are a videographer. You just don't realize it. This instruction video is as good as it gets on CZcams.
I have a Wilkins Zurn Model # 975XL It is leaking out of the diaphragm in the center hole. What is causing this?
The leak out of the hole on the RV cover is one of three reasons or a combination. When you take that cover off the nipple end of the RV assembly may still be stuck in it. The part that fits into the cover has a plastic piece with an o-ring on it. Either the plastic could be cracked or broken or the o-ring is damaged. Lastly, it could be the cover plate inside where the o-ring seals is corroded or pitted. If the corrosion can be cleaned out and it has not pitted the brass you may be good or you may need a new o-ring. But regardless it is one of those reasons or a combination of them. Call me if you need to 801-355-6736
GREAT instructional video!!! My exact unit and NOW I understand it well, Thank You!
How do you drain the supply line? do you need too?
IF you are referring to winterizing, I guess it would depend on your system. For example, I have a stop and waste and it should all run out of that. If your valve is in your home there should be a way to drain it as well.
Thank you for this. I now understand why it's only 1/4 turn.
Thank you. My valve, which I installed myself to please the water district, is 16 years old. This leak happened only once before today. That was 10 years ago. I forgot what what I did to fix it last time. I watched a more technical video earlier today that gave me the confidence to tackle the leak. It amazing what I remembered. But your video confirmed for me I made the repair correctly. No stones or debris. Nothing I could see but a depression of wear in the washer so I flipped it over. Repaired for zero cost. Again, thank you.
You are welcome. Just know flipping the disc won't last as long as before you flipped it as it is hitting in the same spot as the side you just flipped. It now doesn't have any support or strength on the other side. It is intended to be a temporary fix.
Great ...now you have homeowners repairing backflows...they arent trained and qualified to repair and test any testable backflow device !!! Thats why plumbers have licenses to protect our public water utility
I understand your concern. However, they are going to do it anyway and in many places codes allow them to do it. These videos are also not just for them but those that are licensed to do it. Many of them do not understand how to do it either and know very little about installation requirements for them.
Union plumber much?
Thank you for this very important video repair guide.
You mentioned that the washer has a "beveled edge" that goes under the head of the screw. The washer just looked flat to me. Do you mean it is slightly concave? In either case, could you be more specific on what way that the metal washer should go? What are we looking for? Thanks, Crzzy1
The washer shouldn't be concaved. It should be flat. But one side should extend a fraction wider than the other side. The side that should go against the washer is the longer side. And the edge of this side feels a little more sharp. The other side that is away from the rubber disc is more rounded. I have found out since that according to Wilkins it doesn't matter, but I have had an experienced technician of several decades tell me it does matter. I think over time the washer might not be as easy to distinguish the edges as I think they wear away. You should be able to tell by the staining on the washer from the water what side was not against the rubber disc. Not sure if this helped, but I really think putting it on will not be noticeable.
@@backflowsupplyslcut9394 Thank you for the prompt reply! 🙂
Thank you for your sharing. I have the same pressure breaker and I am having hard time to take the bonnet off, it is so tight and maybe rusty. I have tried oil on it but it doesn’t help. Do you have any suggestions? Thank you!
Take a hammer and gently tap around the outside of the housing at the top where the threads of the bonnet go down into the body. See if that will help loosen it up. if you are not using a long bar of some sort to put in between the three "legs" that the screws go into that the canopy attaches to I am not sure how else to get it out.
@@backflowsupplyslcut9394 It works!!! THANK YOU SO MUCH!!
@@qing7 Glad it worked, but what worked specifically? The tapping with the hammer, the long bar to turn it with or both?
Did he just use a tool for a shut off valve....video skipping in 3,2,1
Shut off SOV#2 is all you forgot.
What did I forget about the #2 SOV??
What does the number 4 test cock have to do with the number 1 check valve? You failed to explain how the number 4 test cock stopping the relief valve from leaking means that. Your number one check is bad?
Opening the #4 test cock or if necessary opening a valve down stream that gets a greater flow through the assembly than what is coming out of the relief valve is a means of trouble shooting if the issue is the #1 check or the relief valve. It in effect allows the relief valve to fully close if it is a number one check issue. But if it is a relief valve issue it doesn't matter if water is flowing or not and you will know where to focus your efforts in your repair or cleaning.

Thank you very much for this video. This is so helpful. May I ask you a question? I have to replace a 3/4 valve with a bleeder in my system. I'd like to understand why one valve has a bleeder and the other doesn't? Does it matter which one has a bleeder from the other two? Thank you.
i do not know what you mean by you need to replace a 3/4" bleeder in your system. When you say system are you referring to just the backflow assembly? Do you have the Wilkins 975XL or 975XL2 model? When you say bleeder are you referring to the test cock, the valve with the screw driver slot in it? Is it the one on the inlet ball valve? The inlet is supposed to have a test cock on it. So if you want to replace the test cock only you can. If you have to replace the ball valve with the test cock in it you can get that ball valve, but most models just come tapped and threaded and you can usually just take the old test cock out and reuse it. If you need to replace the ball valve on the outlet side of the assembly it doesn't have a test cock. If you need to send me pictures you can email me at sean@backflow-supply.com or call at 801-355-6736 on Monday. I will be out in the morning, but will respond to your email or call as soon as I can.

thank you! Very helpful video!
Thanks for the feedback.
I got a notice that the test of my backflow prevention assembly failed. The notice said "Assembly Untestable: Test Cocks #1-4" Could you help me know what that means?
Sorry for the delay in responding. I can only assume that the tester is indicating that there is an issue with the test cocks. Have you tried taking a screwdriver out and turning the screw to see if they turn or not? Every quarter turn is open close. It does not tighten. Just open and closes a small ball inside. Please check that and get back to me. It might be best to email me at sean@backflow-supply.com or call me at 801-355-6736. I check these comments on CZcams about once a day.
Thank you for the very clear instructions. You helped me understand the repair and assembly process.
How long can you use a kit after the calibration date has expired? Wondering if it’s a grace period
it depends on the jurisdiction. It is only recommended it is calibrated annually. But some jurisdictions see the date as a hard date. You would need to see what they would allow.
Can I buy that socket adapter to shut off the water?
If you are referring to that tool used at 2:22 in the video, yes you can buy those to shut off the ball valves on backflow assemblies. There are three different sizes. Part numbers WV100, WV101, WV106. backflow-supply.com/collections/backflow-test-kit-accessories
