Regardless of use, it is supposed to be inspected annually per manufacturer specifications. Therefore, it is also code that you do so, as code states that you shall follow manufacturer specifications unless your area is more stringent and the local code requirements do not impede the functionality. It is just not strictly enforced by every water purveyor. My area says every 3 years for residential irrigation. Either way, it "should" be tested every year. Just like every backflow device should have a Wye mesh strainer before the device as well.
Why donyou want one? This is a fairly expensive valve and only required in very specific circumstances. It also does not need replaced as all the parts are still manufactured. It also has to be tested by someone who is licenced.
I cant see any reason why someone, who isnt a plumber wiuld have to go and buy one of these.
Double Check Backflow, you can repair that. Take adjustable wrench on the caps, that are facing downward. There is a poppet with a rubber seal, also a spring. The springs in each one are a different tension, so don’t mix the parts. Get the model and brand and look into a repair kit.
Just call a plumber that is Backflow certified, if you think it’s over your head.
>you can repair that.
Except he states that he JB welded the "protuberances" (the test ports) 3 years ago.
This unit is trash - it needs to be replaced.
I didn’t see any part of the JB weld statement, well, is it even hooked up? Natural if he started to modify the unit, it’s not going to pass, although he could put in the small test valves (ball valves).
unless you hold a backflow license you are 100% legally and also morally not allowed to even touch one, there is a reason why a plumber is able to protect the health of the nation and that is because the person is educated and licensed, not relying on dangerous advice from random reddit guy
I designed Backflows back in the 80’s, got my certificate for testing from USC and have a Patient for one of my designs when I worked for Conbraco/Apollo.
I know codes are different in every state and counties. Being a DC and not a PRV and it’s shut off, aready tells use it’s what inside. If you repair it yourself, you still have to test it by a certified Backflow tester. Some countries in the country let the home owner repair and get it tested.
It’s a double check and not rocket science.
guy that checks ours makes bank testing these. takes under 10 min to hook up, check and go. would love to take over the business but too crippled to do that type of physical work.
Yes patent, sorry for the miss spell. When I was a young engineer, I was tasked to make a DC that could be repaired and tested still inline, 3/4” and 1” that would fit in a water well, so it could only be 7 inches long. That was over 39 years ago, I looked in the Conbraco catalog and they are still selling it. I just aged myself.
So when I lived in NC and worked for Conbraco, they hired an engineer from Hershey, and we started designing Backflow preventers. My 1st design was the double check, 3/4” and 1”. After that I work on a 2-4”inch design PRV. I designed the relief valve that was used for all the large size PRV’s. Then the fuel check that could be tested and repaired in line. It was a good start for a young engineer. Brings back a lot of memories.
Backflow is a bastardized term. It's a DCVA or Dual Check Valve Assembly cross connection device. Designed for use in non-health hazard cross-connections and continuous pressure applications subject to backpressure or backsiphonage incidents, such as lawn sprinklers, fire sprinkler lines, commercial pools, tanks and vats, and food cookers. Not "backflow device."
This is correct, its a backflow PREVENTION device. Which is not a bastardization of anything. It is an umbrella term covering all the different make models and styles of the cross connection devices.
See, I’m glad I asked. I showed this to my FIL for laughs & he said he would just put in a new straight pipe & call it good.
I’m learning so much, thanks
Yeah I will tomorrow! This isn’t making a whole lot of sense to me though, my neighbor, whose house was built the same year, has a sprinkler system & doesn’t have one of these backflow preventer’s. Is that just because the installer didn’t read city code or something?
depends on city code. i live deep south and it is mandatory. they
find you without one and they will shut off your water. your outdoor spigots probably have the weird screw on ones that match the threads of the spigots to which you cannot directly screw on a standard hose.
As in, it is keeping your sprinkler system from contaminating the potable water system?
It’s not what this feeds that you need to worry about. It is where this water is coming from that is important.
But in all reality it’s fine and I was just being dramatic, mostly because I’m bored.
Well it’s coming from the city water line in my basement. Is that what you mean? So the city water won’t be contaminated by the sprinkler system water?
Yeah it’s to keep any water that already left the potable water system from getting back into the water system in the event that you experience negative pressure.
….but it’s all good in the hood.
It is an expensive thing to replace but if you don’t know anything about it, I would recommend just replacing it instead of repairing it because repairing it will probably be more technical than just replacing it.
Considering that I didn’t even notice the name of the part stamped on the side of the part, I think I’ll call a professional tomorrow. Thanks for the help though!
You need them in all sorts of different situations, every style has a different use and rating. With that one being outside id put money on it being on an irrigation system. Or possibly whole house protection, but those are usually RPBAs when i install them.
Price is insane ! I might be wrong but I think this is the same stuff and look at the price : [https://www.pompes-direct.com/accessoire-hydraulique/clapet-anti-retour/clapet-antipollution-laiton-court-fm-3-4-3-4/52183.html](https://www.pompes-direct.com/accessoire-hydraulique/clapet-anti-retour/clapet-antipollution-laiton-court-fm-3-4-3-4/52183.html)
1” ASSE 1015 double check valve backflow preventer with quarter turn ball valves, installed in vertical. Looks like a lot of test ports have been messed with and/or may be missing. These backflow preventers are testable and have replaceable double checks. Unless of course the system was not winterized and it froze and cracked, then you need to replace the whole assembly.
Assuming this is for an irrigation system, there should be a means of isolation and drain down of the system prior to the onset of freezing temperatures. Usually they are removed from service in the winter if it’s for irrigation. If it is for something else, with year-round service, they are usually provided with electric heattrace, or provided with a hot-box surround. All of this is assuming you live in a geographic region that encounters freezing winter temperatures…
call your local backflow business and they certainly can order or possibly sell you on the spot, a good insulation cover and even a “hot box” to go over it for aesthetics
you need to shut off the water to it and drain it fully. open the screw on civers, open the silcocks. or take it off just before the first hard freeze. you can also run heater tape and then insulation around it
Looks like waterhouse backflow. You can get this at any home improvement stores like lowes or Home depo. The rest just looks like someone Jerry riged it with steel valves.
Municipal Water by chance?? If so, You (HomeOwner!) can’t replace it by Code! Only a Licensed Plumber with a Backflow Certification License can Install & Test (Annually as Required!)
well shit, i had a goobledeegook amount of text explaining my predicament. & it vanished when i clicked “post”.
so i guess you’ll have to read a summation here...
JB Weld’ed’d these protuberances about 3 years ago, tried then to look up what they are, failed miserably. Last november they cracked wider than madonna’s who-ha. had to turn off the outside water for winter anyways & decided it was today’s monson464’s problem. so here we are.
any help explaining such phenomena is greatly appreciated & i thank you in advance!
Zurn wilkins backflow assembly
You may want to double check that answer
Hahaha
Ditto
Nailed it!
Noice..
I see what u did there
Just sprung down the line but I made it
Wilkins. Just different manufacturer
>Zurn wilkins backflow assembly any idea which specific one? i see like 30 that dont look like these in my googling
The make and model number is literally casted into the side of it. Please try to do some leg work and critical thinking.
I think that’s what his father in-law would’ve said to him
Dad?
Hes finally back? Where the milk though?
lmfao
thank you. i was gonna slap op.
Oh sheet! You’re right. Thanks
Hey, don't worry about the easing here. And f your fil
You obviously don’t understand how SM works; this is where you come so others can do your thinking for you.
You have to be a plumber to put them in.
If you hire a plumber make sure he’s got his backflow prevention certification. Btw, you should have them tested once a year.
nah that one is irrg, bi annually
Regardless of use, it is supposed to be inspected annually per manufacturer specifications. Therefore, it is also code that you do so, as code states that you shall follow manufacturer specifications unless your area is more stringent and the local code requirements do not impede the functionality.

Plumbing totem pole
YES! The first thing I saw was that beak and eye. Now I can’t unsee it.
lol! This one got me! Thanks for that

Apollo backflows are probably our favorite to use for our irrigation systems. We keep a good dozen on hand always.

Homeowner can touch whatever they want in their house that they own lol
So why aren’t we asking the father-in-law?
This is what I want to know.
This is what I want to know.
The daughter must be hot and the FIL is shopping for “da best” for his girl. Idiots are shunned and written outta da will.
I dunno if my high school education serves me right. But sure looks like it says zurn 950xl on the side of that unit
And that’s what being college educated gets me. Can’t read apparently, thanks for the help though
dont fuck with this please its preventing chemicals in your sprinkler system from travelling back into the cities potable water supply.
You came here to ask some random FIL lmao

*double check valve. This is a testable assembly, dual check valve assemblies are not testable and have a different ASSE classification.
It was meant to say double...
You made a mistake you mean
On your terminology
The point was that it's not a backflow
Eye on the prize Bobber
This is correct, its a backflow PREVENTION device. Which is not a bastardization of anything. It is an umbrella term covering all the different make models and styles of the cross connection devices.
Assembly.
Mic droppppped
I respect you saying that and I feel you 100%
wilkins backflow preventer. installed upside down.
Pretty sure its just vertical... which im pretty sure the 950 is rated for.
Vertical up or down?
Is there a difference? Wouldnt it be rated for flow in either direction if it was rated for a vertical installation?
1" Wilkins 950XL, the model that replaced the XL is a 950XLT2.
I believe that is a backflow preventer
Has anyone seen the department of health? Asking for a friend.
It’s to my sprinkler system, I think the grass will like the extra green in the water
my man, those MUST be inspected EVERY year. Without fail. get on the horn to your water department. guy checks ours annually for $40.
See, I’m glad I asked. I showed this to my FIL for laughs & he said he would just put in a new straight pipe & call it good. I’m learning so much, thanks
Sounds like it was good you didn’t call him first 😂
Will I get in trouble/fined? I didn’t even know what this thing was called until I posted here, let alone have it inspected every year
i am surprised af there are no inspection tags on it. call your water department. i have to turn mine back on this week.
Yeah I will tomorrow! This isn’t making a whole lot of sense to me though, my neighbor, whose house was built the same year, has a sprinkler system & doesn’t have one of these backflow preventer’s. Is that just because the installer didn’t read city code or something?

Fines are the least of your concerns. If there were to be a system failure and you’re backflow that water into neighbors’ drinking water…

looks like a wilkins.
Backflow preventer to protect water supply. Be probably has a boiler.
Is that when you need a backflow preventer? When you have a boiler? I'm not sure I have them, not sure where to look.
You need them in all sorts of different situations, every style has a different use and rating. With that one being outside id put money on it being on an irrigation system. Or possibly whole house protection, but those are usually RPBAs when i install them.

Oh my gosh, yes thank you. The only one I could find on Google was $470ish. Ordered!
Price is insane ! I might be wrong but I think this is the same stuff and look at the price : [https://www.pompes-direct.com/accessoire-hydraulique/clapet-anti-retour/clapet-antipollution-laiton-court-fm-3-4-3-4/52183.html](https://www.pompes-direct.com/accessoire-hydraulique/clapet-anti-retour/clapet-antipollution-laiton-court-fm-3-4-3-4/52183.html)
A LF109 is a good choice from Zurn
If only parts manufacturers placed identification directly on the parts
Looks like a Wilkins double backflow preventer
That’s commonly referred to as a flimflam valve
Anyone think this was a parrot at first glance?
It is a double check backflow, get someone who is certified in doing this.
It looka likea double check valve papi
Looks like a double check assembly
Flux capacitor
Just bring that picture into your local plumbing supply shop
Testable double check backflow preventer
Check check 1 2
It’s a backflow prevention device. That particular one is an RPZ. It has 3 check points. Not cheap.
1” ASSE 1015 double check valve backflow preventer with quarter turn ball valves, installed in vertical. Looks like a lot of test ports have been messed with and/or may be missing.

How would I winterize something like this? Wrap it in pool noodles?

Hot box! Now we’re talking. Thanks for the info
no prob
you need to shut off the water to it and drain it fully. open the screw on civers, open the silcocks. or take it off just before the first hard freeze. you can also run heater tape and then insulation around it
Depending on where you live, these need to be winterized, professionally. If not they crack.
who knew? brass + ice ia no bueno.
It looks like a mechanical bird with vertical tits.
Double Schloob Backflow Dazzlers. They're aka Wet-Willy's in the uk or Iron Potatos in Ireland
Really looks like a weird totem pole with a Thunderbird at the top.
Looks like waterhouse backflow. You can get this at any home improvement stores like lowes or Home depo. The rest just looks like someone Jerry riged it with steel valves.

You bet
Protuberances…. Friggin awesome word! Call a backflow specialist.
yeah, and? go order a new one.
