What is the material that this is made out of. It looks like plastic. You need to state that.

After 3 months of no issues, I started to see a steady stream of water from my backflow preventer. I have my water timer, backflow preventer, pressure reducer and then the irrigation tubing in this order. I put a new backflow preventer in and same issue immediately. Short of changing out the pressure reducer, any ideas on the problem? When I remove the backflow preventer altogether and hook the water timer directly to the pressure reducer, everything works fine. But I'm guessing this is not a good idea. Any help is appreciated!
Asked by: irrigationnewbie
Interesting. Is there water still coming out with basically normal flow with your drip lines (maybe a touch less depending on how much water is coming out in that steady stream)? Maybe there's a block somewhere along the line that is applying force? This is just a guess, hopefully almost a year later you found the issue!

100 psi Hose Thread Backflow Preventer is rated 2.2 out of 5 by 22.
Rated 1 out of 5 by from Bought 4 of these in 2017. They worked fine for few months, then three of them started to leak on... Bought 4 of these in 2017. They worked fine for few months, then three of them started to leak on sides via micro cracks. And it was summer, this was not a freezing issue. And was not a pressure issue as well, since there is a whole house pressure regulator/reducer in place to prevent sudden pressure changes in the line... I just assume at this point that this is not meant for a regular pressure even though it is rated 100psi...

I have to re purchase this product annually because every single one cracks over the winter months. They are stored in my garage. However, when hooked up to my irrigation system, they work great.

Rated 5 out of 5 by from Anyone complaining about this product "leaking" does not understand the purpose of this product. ... Anyone complaining about this product "leaking" does not understand the purpose of this product. This is not a check valve. It blocks back flow and releases the pressure by redirecting the water out the sides of the valve. I works great for what it is designed to do. If you are looking for a one-way-valve that doesn't "leak" then you want a check valve.

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.
