100 psi Hose Thread Backflow Preventer is rated 1.8 out of 5 by 15.
Rated 1 out of 5 by from 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.

Rated 1 out of 5 by from Worked for <1mth before it started leaking bigtime Worked for <1mth before it started leaking bigtime. I plan to take it back to Home Depot and see if they will exchange it else will pick up something better.

Rated 1 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 3 out of 5 by from 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.

Rated 1 out of 5 by from 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.

Rated 1 out of 5 by from A piece of junk I have purchased several of these units for my drip irrigation system and all have eventually developed pin hole leaks in the thread area. I'll never buy another.

Rated 4 out of 5 by from 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.
