Review: Works quite well and easy to install. - After trying a much more expensive regulator that failed, this has turned out to be a pleasant surprise. Originally purchased to remedy ice maker problems caused by high pressure water supply that was splashing all over on the fill cycle, causing lots of things to freeze up. This cured the ice maker issues but it does take longer to fill a glass of water. A small price to pay for the benefit
Review: Regulate your pressure and stop ruining your ice maker valves from too high of home water pressure. - Ordered on saturday, the thing showed up on sunday! I purchased this pressure regulator for my refrigerator ice maker/ water dispenser incoming water supply. I've never used the slip and lock type connectors before. I was a bit uneasy about their ability to seal properly, I called a friend who does home remodeling and he said he loves them. Well I cut my plastic lines with a razor and inserted the lines into the regulator and the seal is water tight. Super easy to install, took honestly less than 5 minutes. Now the reason I put this regulator on in the first place, is that my ice maker / water dispenser valve assembly ruptured or fractured to the point that water was leaking from the back of the refrigerator from the valve. I decided to check my home water pressure because these ice maker valves are only light plastic and they prefer to have around 45-60 psi of water pressure on them. Check with the recommended pressure from manufacturer. I found my home water pressure was around 120psi....that is what broke my ice maker valve assembly. The home water pressure is not recommended to exceed 75psi Max! I had my home pressure set on the high end for a better shower experience, but through the years the watts water pressure regulator decided to malfunction and allow full street or line pressure to get into my home network. With this high psi, its no wonder I've replaced my ice maker valve assy twice in the last few years. This inline regulator will keep my refrigerator line pressure at a perfect 45psi. Well worth the moneyspent, now I have a complete system for the refrig. I highly recommend using one for protecting your ice maker system, and be sure to check your home water pressure at your faucet or spigot outside, so you know if your water main pressure is regulated properly into your home, before you blow water lines and water heaters.!!!

waterline to the icemaker on my fridge kept springing leaks. Used this to cut the pressure from 70 to 40. Ice maker works ok and so far no more leaks.
