While waiting for my house to be built, I have had to live in my RV for several months.. Initially,I bought a cheap brass pressure reducer, which worked too well, and the pressure was terrible. I looked into the adjustable pressure reducers, but build quality seems to be a recurring problem with them. One reviewer suggested this product as an alternative, and in desperation I ordered it......and I am glad I did. I have used it daily for almost 3 months with no problems at all, the build quality is good and the pressure supplied is fine. Best of all, it has not been a problem for the pipes in the RV. The flow from kitchen faucet and the shower is dramatically improved and this simple product makes my life that much better. I highly recommend it.
