Rated 1.9 out of 5 by 14 reviewers.
Rated 1.0 out of 5.0 by Broke after 25 days Waist of time and money. Broke after about 25 days. When timer is off, it will let the water keep running and leak (more like pour) from it outlet. August 25, 2016
Rated 1.0 out of 5.0 by Broke after a few months I had this for my soaker hose that surrounds my house. It only has the weight of a small timer and small rubber hoses on it. The backflow preventer spontaneously broke one evening. Lucky I was home and my faucet only leaked at full blast for about an hour before I noticed. Complete junk. There was a 180 degree break on the female threads. August 5, 2016
Rated 5.0 out of 5.0 by I'm glad I found this I got this to use as a backflow preventer on a hose-end garden sprayer (actually, a 1 gallon Mixer-Proportioner). This product was very reasonable priced. March 15, 2016
Rated 3.0 out of 5.0 by Please note To all the negative reviews: please note that it is warranted for THREE years. I suggest there are many satisfied users out there with only the disgruntled replying. I have one that worked great all last summer, this year it leaks. Can't blame the device, I left it on the hose in my RV over winter & it froze. Leaks but still works. September 11, 2015
Rated 1.0 out of 5.0 by Leaks after less than a year Used it for about 6 months then took it in for the winter. When I re-installed it in the spring, it had sprung several pinhole leaks. It's a piece of junk. April 16, 2015
Rated 1.0 out of 5.0 by Save your $$ The DIG system has worked great all except this backflow preventer. The first one came in the kit I bought. It actually lasted a year but two months into this watering season, it developed a big crack and leaks bad. I added a second system in another part of my yard and built it by piece instead of the kit. The backflow preventer off the shelf lasted three watering cycles before developing about 9 pinhole leaks. I'm afraid to buy any more because I'm wasting my $$ and gas taking stuff back. July 27, 2014
Rated 1.0 out of 5.0 by This is the Achilles heal of my DIG systems - it leaks Some last longer than others, but this part almost always fails within one year and the leaks are not slow. It's seems to be a weak point. I'm looking for another solution to this; this is a great shame because this done for public health reasons and its functionality should be high because otherwise people not opt not to use it. I'll look for another part that has the same function. September 2, 2014
Rated 4.0 out of 5.0 by All In How You Use It My backflow preventor leaked from the minute I installed it. The problem wasn't the product, it was how I was using it. I called DIG customer service which is very responsive and helpful. They said if I have it downstream from the water source, it can leak due to pressure. I moved the entire assembly to the spigot off my house and the leaking stopped. August 4, 2014
