Clarification question - remove problematic Zurn Wilkins 975XL backflow prevention valve
In another thread we discussed a constantly problematic Zurn Wilkins 975XL
1-inch backflow-prevention valve, that doesn't actually do anything (since it's on top of a hill). I thought I had fixed the leaking valve - but it started leaking again, so, I completely give up on fixing that poor design since I've taken it apart a dozen times and there's nothing I can see that is wrong with it. Yet it leaks. And, even if I did fix it, it will invariably leak again soon. I'm not a plumber, so, my only question is clarification of the two spots that were suggested to *remove* the valve (and replace with a pipe). Would you kindly look at this picture and advise me which location is the removal point? (I'm confused because twisting a pipe in one direction simply tightens it in the other direction.) http://i.cubeupload.com/tHjqRh.jpg |

Once off, you can take apart at the red, insert a solid pipe, and then reconnect at the yellow. Figure out how a "pipe union" works! I don't suppose you have taken seriously the obvious thing to try: insert a filter on the inlet, to keep out the crap that is likely causing the problem. You call it a "poor design", but there are millions of these in use with no real problems. |

But it appears to be installed in a location where one isn't needed and will do absolutely nothing positive. The only possible reason would be if there is some code that someone interpreted to mean that it was required. As D has explained it, this valve is on the output of a tank on top of a hill that feeds water downhill to his house. And I agree, it comes off via the unions shown by the yellow. He'd probably realize that himself if he just unwound the tape around them. |

Thank you for your patience, as until you said that, I hadn't realized you remove it at the (yellow) pipe unions first, and only then, you remove it at the (red) ball valves. Since the pipe nipple has to be pre measured, is this the distance you'd use (midpoint between the two shutoff ball valves)? http://i.cubeupload.com/nwV7Rt.jpg Figure out how a "pipe union" works! My only experience with pipe unions were with the white plastic pool pump pipe unions, which glue onto the incoming pipes, so reverse threading wasn't an issue in those repairs - and exact measuring wasn't necessary because I could always easily trim off excess pipe. I don't suppose you have taken seriously the obvious thing to try: insert a filter on the inlet, to keep out the crap that is likely causing the problem. If the valve actually did something, I might take its repair more seriously. As it is, it's on the top of a hill, so, the chance of water being pushed or siphoned into it has got to be near zero. To be clear, I have been repairing this valve for years. I'm just sick of it. It's a poor design. You call it a "poor design", but there are millions of these in use with no real problems. Given that this 1-inch Zurn Wilkins 975XL backflow preventer requires constant service, the support is pretty good. Today I called 855-663-9876 and received a call back from a technical support guy named Daniel at 805-238-7100. He said that I should flush the valve by removing the #1 poppet assembly, and then the #2 poppet assembly, and then to put my hand over the #1 opening and then turn the water supply on. Since my water supply is something like 70psi, that shot water out almost 10 feet. There is no way there is still debris stuck in there - yet - still it leaks. Daniel told me the classic test is to see if the water leaks in both cases: 1. When there is no irrigation in use, and, 2. When the irrigation is in use. Since my Zurn Wilkins 975XL backflow prevention valve only leaks when there is no irrigation in use, he said to further test by: a. Turning off any sprinklers (if any) b. Turn both check valves on (in my case, this starts it leaking) c. Shut off the #2 check valve - if that stops the leaking - then #2 is fouled. (In my case, this did not stop the leaking.) Daniel said that if the test above didn't stop the leak, then the problem is most likely the #1 check valve, or sometimes the relief valve, both of which I have taken apart umpteen times already. He said in that circumstance, I should just replace the entire innards with the three separate repair kits, which I can find on Amazon for $100: https://www.amazon.com/Wilkins-RK114...=pd_bxgy_469_3 The required tool for removing the three seats is about $50 https://www.amazon.com/WILKINS-SEAT-...=pd_bxgy_469_2 So, for about $150, I can probably fix the dastardly thing. But, what's frustrating is that I can't *see* anything wrong with it. It's *not* fouled. Note that a brand new Zurn Wilkins 1-975XL is about $250: http://www.sprinklerwarehouse.com/Wi...ies-s/9537.htm |

I think it DOES get to freezing where you are, although I forget if you are at the top of the hill or how far down. There have been some damn hard freezes up there in the not too distant past, and snow on the ground for days. When did you buy your property? But why did they design these pipes to be out of the ground if it can get to freezing? It is an anti-siphon device. |

There have been some damn hard freezes up there in the not too distant past, and snow on the ground for days. When did you buy your property? There is sometimes a thin layer of ice (about a millimeter thick?) on puddles on the ground in the morning, so, I agree that it *can* get to freezing. We get snow every five years or so, and, once in a while, it sticks for about a 1/4 inch or so, but only for about a day or at most two. I'm a few thousand feet up, so the clouds are almost always below me, where I can look in on airplanes coming in for a landing below me at the local airport as they disappear into the valley fog until about noon when the daily fog lifts (and returns again to cover the lights of the valley by midnight). I've been here about a decade and it has snowed maybe twice or three times as I recall - but it's just a light dusting that almost never sticks. The issue is that they *knew* what the weather was when they wrapped those pipes in that black tape - so it must be designed to take it as it doesn't really stay cold here for very long (especially not in the past two years). |

The 1-inch pipes above ground to each side of the valve are all galvanized. Below ground, a foot or so away, a used the 2-inch red-handled PVC shutoff. Then the pipes come back above ground at 2-inch galvanized into the pressure pump equipment in the pump house. This picture shows the water pipe to the right going from the pump house into the ground, and then one of two valves underground (one for the house, the other for the irrigation system). http://i.cubeupload.com/cMcINF.jpg I think it's odd they go from steel to pvc to steel, but they do. The PVC seems to be only underground though. |

Used on underground pipes to wrap joints to avoid corrosion. The insulation value is very small. If freezing is an issue, wrap to whole thing with real insulation, covered to avoid water and critter intrusion. A small amount of water flow occasionally should then keep it from freezing. |

I have to agree with you, after reading the package at the store for the 10mil black sticky wide pipe tape. The package says it's for protection from corrosion. http://i.cubeupload.com/rMhpw7.jpg Of course, it did nothing for the corrosion on the *inside*! http://i.cubeupload.com/Wrh9jB.jpg |

Would you kindly look at this picture and advise me which location is the removal point?

One of those guys with his butt crack showing would be proud and he'd have charged $200+ Thanks for adding me to honorary plumbers-crack membership! It's a temporary setup (until I look more closely at what's really disabling the back-pressure valve) - which allows me to analyze the valve in my own sweet time without being super frustrated by the leaks. Speaking of leaks, I had expected a leak when I first turned it on, but it was water tight from the start. The galvanized pipes are a bit crudded up inside though ... http://i.cubeupload.com/Wrh9jB.jpg |

Again, I must thank you kind folks because you give me advice in three great ways: 1. You tell me exactly *where* to start (e.g., at the yellow connections). 2. You give me ideas for solutions (e.g., the threaded pipe nipple). 3. That gives me the courage to start the job (I analyze more than most because I'm actually more timid than most of you when initially tackling a repair job). http://i.cubeupload.com/7s3ouu.jpg |

Your pencil pushing, bean counting skills allow you to think critically :-) Did you turn the two ball valves (test) them? No that it matters so much with the valve removed. |

Did you turn the two ball valves (test) them? No that it matters so much with the valve removed. Yup. I cleaned the two ball valves out and tried to lubricate them with pool grease, but the grease didn't really do much to make the downstream valve easier to turn (or, maybe shoving grease on the inside ball wasn't the right way to lubricate them?). http://i.cubeupload.com/rMhpw7.jpg |

You never learn to fix things until you start, and the more you do it, the better you will get. |

I did learn a bit, e.g., I put the teflon pipe dope on the threads but I didn't bother with the black 10-mil tape, after asking at the hardware store what it's for. I also made some unexpected mistakes. For example, I never could get the downstream pipe joint to open because the entire assembly kept turning underground instead! http://i.cubeupload.com/7s3ouu.jpg |
