Interesting vidéo👍. In France we use this system (called "disconnecteur") only at the water filling point of a heating circuit. For tap water, a device called "clapet anti-pollution" is used; it's made of two valves on each side of one way check valve. I like your vidéos, for it shows thé plumbing ways and uses we dont have here. (Sorry for my poor english 😓). Bye 👋🇨🇵

Had to add one in Oregon for irrigation system. City requires annual inspection by someone certified. $40/yr so far.

Not sure if its true but i heard that a slaughter house had a back flow issue and siphoned blood into the water system and people got blood out of their faucets and thats when they started getting strict about back flow. Its a story i heard from an old journeyman of who was training me. Might be totally bs

@eluckeymusic Ай бұрын

There are a lot of horror stories. In the book I use in class, it goes over real incidents that have happened. Aspiration occurred in a line at a morgue, sucking up the blood and embalming fluid back up into the faucet and contaminating the water. Other incidents of chemicals being sucked back into city supplies and even gases. One incident was propane gas being sucked into the water main from the gas company, causing an explosion inside a home downstream.

We install backflows in Washington State when we install outside irrigation.

Its easier to place the RV assembly inside of the brass cap and then place it into the vessel. Make sure all o-rings are lubricated as well.

Since you deal with these, I have to have one for my irrigation system. The PVB’s I’ve looked at aren’t lead free will that be a problem long term since I’m tying into my mainline? Or would be better just to use an inline back flow preventer?

Depends on if you filter your water or not before drinking?

I have a problem once in a while where if I am taking a shower or using my washer or flushing the toilet where I get bubbling noises in my kitchen and bathroom sinks. Is this a back flow problem. I have a well and septic tank.

So i do have a question: Our line was stopped up and when the city had came to check, they said that wipes were found inside. Now, they said it came from our house but no one flushes wipes at all. We are confused where they came from or if it is from another line or neighboring house.

@jessekatie8985 Жыл бұрын

possible. find out if you system is pressurized or gravity only.... if you sit higher than a neighbor any air wants to escape upwards- potentially taking other things with it

@libsrmarxist 2 ай бұрын

I installed a backflo preventor in a Lowe's and it started spitting out water from the vent just minutes after I turned the water back on. It's on a 3/4" line that feeds the misting system in the outdoor garden. Would hammering from the use of let's say the toilets and urinals cause this? If I installed a spring loaded check valve in front of the preventor would that eliminate the spitting?

Also gotta check the outlet ball valve is shutting off completely. If not the check can fail

@uterotourettes15 8 ай бұрын

A shut off valve won't cause a check to fail. You will fail your annual inspection though without a proper working #2 shut off valve.

@@uterotourettes15 you just repeated what I said. If the #2/downstream valve doesn't shut off. The test will fail and water will come out of the relief port....because their is no negative pressure, because the outlet valve is still working
