  1. Darnell Smith

    Pretty smooth valveThis valve was cheaper on Amazon than my local irrigation supply warehouse. The installation was straight forward and done by an expert in valve installation (myself).

  4. Bongu

    It is a dual check reduced pressure zone deviceThe only drawback fo this product is that it is not certified to be lead free. This device is great for my application, irrigation safety. Easy to install and does the job it was intended for. Highly recommended for a DIY project.

  6. J Gaddabout

    Really good backflow preventerBest I’ve found over the last 30 years for my irrigation system. Easy to winterize by removing working components and storing them in antifreeze solution in my garage.

    Backflow preventer arrived brokenThe backflow preventer does not work and I know will probably have to buy a repair kit for it. I am extremely disappointed, especially since I had to wait months for it to arrive.
