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

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.

Save your time and frustration; do not buy the cheap ones with holes (they leak out of holes and don't work). This is the one you want to connect to your programmable outdoor hose water faucet. The cheap ones do not manage the water flow properly and drowned my potted plants, these on the other hand, work perfectly and plants are getting proper water distribution again.

Increíble que no puedas encontrar algo tan sencillo como un regulador de presión en Home Depot. Este regulador lo uso para riego por goteo junto con un B-hyve Temporizador de Grifo ya que mi casa cuenta con presión alta y eso ocasionaba que la unión de las mangueras y el aspersor se desconectaran. Con esto solucioné el problema.

This PSI Regulator is a good quality but looks like 25 is not enough for watering 20 big plant containers

I attached it to my water line coming from my well. I needed to reduce the pressure to my green house misting system to insure it worked properly. It works great and definitely worth the money
