Back-flow Preventers

[TomC_AZ]

Ok this one intrigues me. I have not seen them at camp sites but do know what they are since all my houses here in AZ have had them. But I also have never hooked up my trailer to my house so never used the regulator on it. I have only filled the tank up. Can't you just flip the screen washer over and it still work without crushing it? I actually just did that with a brand new one that just so happened to be sitting on my desk and it fits that way just fine... I am missing something?

Also, wouldn't it be simple to just tack weld them on and not get stollen but yet simple to remove with right tools if actual maintenance was needed? Might also make those unknowing what it is not take/remove them. Than again its a crazy world and people will prob still try and break more! Of course, Gov inefficiencies never amaze me especially frivolous financial related ones!

Required by code since at least 2015 for outside faucets. Type of device depends on what you are protecting, ie fire suppression system, sprinkler system, etc.

Sure can. Either flip the screen, or use a regular hose washer instead. My first experience with one years ago went badly. I had never seen one, and thought it was a pressure regulator of some sort. When I didn't flip the screen, the flow and pressure was terrible. I live and learn.

They do have some plastic and rubber components inside, so they can go bad and need replacing. That's probably why they're not always secured permanently.

Yup, most people think they are pressure regulators!! I worked in maintenance in a Colorado State park and we had the same problem!! We painted them red and even posted a sign on the spigot saying not to remove them!! Some still were removed

Interesting. I learned something new about these. I had no idea.

Yes, because theft is a recent phenomenon and has never occurred until this decade.

They didn’t have to invent the first lock until 2002.

My first time post here!!

Just a thought. Why not put loctite on the threads. It will be difficult to remove and not damage the threads

So how are you going to get enough pressure in your RV system to over ride the pressure in the supply line? My pump puts out a maximum of 40psi. Most supply lines I have seen are at least 60psi, some much higher and there is no way it's going to back flow water into the supply line. Plus, if my water was that contaminated to cause a problem we would be getting sick, packing up and going home.

Just another government regulation that makes little sense. The stupid screens in the "Preventer" cause more problems than they prevent.

My $0.02....

This happened to me during a flood. We were in Beaumont, TX during hurricane Harvey. Knowing the hurricane was coming I filled our freshwater tanks. During the afternoon the water in the campground started to rise and it stopped just below the floor of our trailer. Then the city water system shut down and was off for several days. Later when I turned on my pump nothing came out. Turns out the tank was empty. Now where did that 80 gal of water go? The only explanation I could come up with was that it had back flowed into the now empty city water mains. The campground did not have valves installed.

Interesting, but I would think that if the water system was that compromised it was probably so contaminated anyway it would have been unusable. Frankly, I don’t trust campground water systems and always travel with my 65 gallon tank full. I can go 4 days without connecting my water hose. Over the years I have been to campgrounds that had e-coli contaminations, iron bacteria contamination, rusty, smelly water. The idea of putting contaminated water into my RV is something I am very careful about and so far have been lucky.

Where do you refill then if you are on a trip that lasts longer than your water supply? We have been full timers for 9 of the last 11 years and camped several years before that. I've never had a problem with campground water.

Yes, the water system was contaminated at that time as the pumps that supply water to the purification plant were underwater which caused them to shut down. That happens in hurricanes which is why I had filled my tanks before hand. If the water was still in the tank I would have had enough to last until it was back on in a few days. Then we had to boil water for several days and only drink or cook with bottled water.

We will then refill when necessary, but use bottled water for cooking and drinking. It the campground is some place we know and trust because of prior use then we will fill up our tank. Once back home we will sanitize our tank before the next trip.
