Below-grade mounting is absolutely, positively, no reason to downgrade system protection. In the giving of advice, location must be pinpointed. Then advice can follow. Conjecture and aesthetics need not apply to a question on backflow.Well, I've been in this argument before.
I'm not encouraging someone to go from high to low. I never told the guy to get a double check, I actually said he pvb is working correctly and doing it's job. However when the potential of a problem from a irrigation system is low, I don't see a problem in saying it's okay to use a double check.
My main reason why I support double checks is because they are rated to go below ground.. Which in my opinion a green box in the ground looks sooo much better then a piece of copper pipe and brass assembly sticking above the ground somewhere around the yard/ house.. rp's can go underground too as long as they have proper drainage.. Which for a rp could be difficult
My second reason is because I personally feel double checks are completely fine for irrigation systems. I think All back flow devices should be tested Annually, or every 2 years to ensure they are properly working.
I was just in hawaii and saw Many many Rp's and PVB's next to street curbs and meters . horrible and ugly installs . Soo many potential hazards.. not to mention crack heads can easily steal them.
You have received incorrect information from your town. The state of New Jersey requires toxic-rated backflow prevention for lawn sprinkler systems. This has been the law for over 20 years. That a municipal office hands out incorrect information is not all that unusual, especially if their learning comes from before 1990.Op here. Why am I wrong for getting a dcva? From what I've read, it works. My town seems to require "a" backflow preventer device. EDIT: my town allows anti siphon valves, double check valves, PBV and one other type that I can't remember. Secondly that PBV, from what I've read can open up and cause floods. Why take that chance?
Not that it matters now, but noone answered my comment about the auto drain plugs that I have installed and if that can cause a PBV to gush water.
BTW, my system works great.
I bought a Febco DCV
Anyone want a free slightly used Toro PBV?
