    $80 for this is a rip off. I bought an identical one last year, very similar box and great quality, for $15 at 鶹. They are trying to hit a home run and I will look somewhere else. This is a brass anti siphon valve, 1/2", not a complex backflow preventer.

    5.0 out of 5 stars Great replacement for plastic

    The one that comes with the RV is really cheap plastic and under the bathroom sink. I ordered this one as a replacement before our first trip. This is heavy and seems really quality. I've only been on a couple of trips with it but am very happy. I think it is well worth the extra money.

    5.0 out of 5 stars Best For Topping Off Swimming Pools
    Reviewed in the United States on October 15, 2023
    Verified Purchase
    Backflow preventers are required for water top-off lines to swimming pools. This US-made Watts version has long been the industry standard. They don't last forever; but they work better and last longer than alternatives. If you are replacing an older version of this model of Watts, this new one will fit the same, without soldering, done in a few minutes.

    We added brass PEX fittings for 1/2" PEX to replace the improperly installed, cheap, plastic vacuum breaker valve installed on our RV for the black tank rinse system. It works fantastic and substantially decreases the chances of a failed plastic vacuum breaker valve at the worst possible time.

    Had to replace mine on a Hobart LXi dishwasher. Well built part out of good metals. I did take it apart to see the internal parts as well. The plastic, and rubber looked well built too. Easy to replace.
