Works as described. I have a Digiten gauge on my 4 gallon tank. At a pressure of 55 psi / 0.37 MPa, the effluent stopped. After the faucet was started to relieve the pressure, the effluent was resumed at 35 psi / 0.24 MPa. I have an iSpring 5 filtration system. In the picture, the red is from the tap water to the reverse osmosis system and the white is from the filter line to the make-up faucet in my sink.
