Review on 🚰 Oversized Commercial Reverse iSpring RCB3P by Andrew Webster

/eight. ' is the incoming water line that helps, but I'm not sure it does anything significant if it immediately goes back to 1/4 inch, including the drain and faucet lines. Otherwise the device worked great and there was no free leakage out of the box. Delivers great tasting water, less than 20ppm, starting at 325ppm city water. I haven't officially tested the flow but I think with the good incoming city pressure we have the unit will be pretty close to 300 GPD. It filled our 14-gallon tank in under 30 minutes at 130-140 psi on the gauge while running. I'm happy with it! If you're looking for something that performs better than your standard sink mount but still costs less than $750 after you buy the tank, this is it.
