Rated 2.5 out of 5 by 13 reviewers.
Rated 1 out of 5 by Poor quality Bought 4 and 2 worked. Bought 10 more to try and get 2 that worked and all 10 failed -just squirts water out the tiny side hole flooding the valve area. Also had difficulty with threading onto hose connection - some say it is a thread problem October 5, 2014
Rated 5 out of 5 by Best purchase I've ever made on an empty stomach The 25 PSI 3/4 in. pipe thread pressure regulator was the finest 25 PSI 3/4 in. pipe thread regulator that I have ever seen, let alone to own one. The threads were perfectly molded and allowed a perfect fit for a 3/4 in. pipe thread hose fitting to be installed. Also, it was very light weight making it easily transportable and ease of installation. Additionally, the color of the unit was perfect for use in a flower bed. Since this 25 PSI 3/4 in. pipe thread pressure regulator was installed, I ain't blowed out one single soaker hose. I'm gonna buy me some more of them little boogers. July 29, 2014
Rated 1 out of 5 by Really Bad Design I have tried many of these in my drip system, most have failed. I have replace several only to have them fail again. The problem is the design of the regulator piston which is simply a molded plastic tapered seal. The piston seal fails and water leaks past to the vent hole on the side and then it floods everything. I would think Home Depot would evaluate the products that they sell a little better. I am going to have to find something else to work in its place or replace the entire system. November 17, 2013
Rated 1 out of 5 by 25 psi is way to high for soaker hose I ordered this thinking it would be better than the little blue disk that came in soaker hose. Will be returning asap. August 7, 2014
Rated 4 out of 5 by Product redo I added this product to my garden water system to reduce the pressure and help with line breaks. Within the first use the rear seal began leaking. The problem with this item is the male end and female end. I had to purchase two other adapters to install this product. Wasn't very efficient and didn't really reduce the pressure. July 22, 2014
