Senninger Pressure Regulator 25 PSI 3/4" Hose Thread Drip Irrigation Pressure Reducer Low Flow Valve - Landscape Grade High Performance White

I have a several of these and they are well built and work great. Easy to install on a irrigation coupling using a 3/4" to 1/2" Irrigation System / Faucet Hose Adapter fitting. I had an initial concern about the minimum stated flow rate of 1/2 gallons per minute as I have a couple circuits with only seven 2-gal per hour emitters, which equates to about 1/4 gallons per minute, or half the stated min. I checked the Senninger and got a response that they would still reduce the pressure but may vary 3 or 4 PSI higher or lower than the 25 PSI target depending upon the input pressure; certainly a livable tolerance for my needs. Bottom line is they still work OK and I have had no issues with emitter failure or excessive drip rates. They might cost a little more but are a good value.

Exactly as described and clearly a quality product.

The item matches the description perfectly. It is built to be heavy-duty, ensuring durability and strength, making it ideal for demanding tasks. Additionally, the price is quite reasonable considering the quality and performance it offers. I wholeheartedly recommend this product to anyone in search of a reliable and sturdy option.

Update. While static pressure check will not work (see text) neither does a dynamic pressure test work under certain conditions. My initial test ran from the regulator to a Y, off one leg was the drip system main lines but no emitters were installed, on the other leg was a hose where I regulated the water flow at 1 gal-min. This failed but I do not know why. I added some emitters (24 0.5 gph emitters) on the drip side and reran the test and the pressure was a steady 25 psi as expected. I also found that my vacuum breakers interfere with this unit (I have American Valve brass). I changed out the vacuum breaker to a Rainbird plastic between tests so this may why it worked.

Depending on the type of drip irrigation system you have you may need a pressure regulator. Many of the drip irrigation systems are designed to operate around 25 PSI for operation. The Senninger pressure regulator 25 PSI 3/4 hose thread was designed to give 25 PSI and has 3/4 GHT male and female connections.The first picture shows my test setup. You can see the pressure regulator followed by a pressure gauge and a small 4 emitter drip setup.The second picture shows the pressure gauge with none of the emitters running and the pressure is 72 PSI.The third picture shows the pressure gauge with 1 emitter running is about 30 PSI. The pressure with all 4 running was also 30 PSI.This pressure regulator has been working fine in my drip irrigation setup. I created this review to try to make a more scientific description of its performance. I will buy another Senninger when I need my next regulator.

Please stop a second and read this note as u might have missed the memo 🤔U need T plus 2 to connect this device and u should have no water leaks🤔Also keep in mind this device is a psi flow control and not a psi presently control device😦That means if ur psi is 100 psi then the water flow psi will be 25 psi but if the flow stops and u dont have a automatic shutoff device, the psi will return to 100 psi🙄If ur using a soaker hose with an automatic shutoff device then this is the device u need😏If ur want control over all the psi then u will need a psi auto adjustment device normally called water pressure regulator 😐

These regulators work just fine. The reviewers that measured the pressure and say that they don't work, didn't measure correctly nor did they read the instructions on the item listing. These only regulate while water is IS FLOWING in the system. They do not regulate in a static system.

leaked so returned
