Review: Installed this in my 2018 Fuel Toy Hauler to provide filtered water to my sink. Super easy install with no leaks. I spent 2 hours at Home Depot looking for this, asking for help, and finally walked out. I looked it up on desertcart in the parking lot before driving home and hit the buy now button. I should have saved myself the drive.
Review: Installed a Frizzlife 3-stage filter in the RV which came with the wrong size valve. This valve worked perfectly in my Keystone Montana High Country 5th wheel.

Installed a Frizzlife 3-stage filter in the RV which came with the wrong size valve. This valve worked perfectly in my Keystone Montana High Country 5th wheel.

### ⭐⭐ Review
*by M***R on 25 November 2021*

This product worked fine for a little over four years. Then the valve started leaking when closed. I removed the valve handle and tried to tighten the interior core as I didn't know how else to repair it. The leak soon returned. In the end I left the valve open and installed a 1/4" dripline valve on the hose to control flow. If you are fine with a basically throwaway product, this adapter is great. I was hoping for something longer-lived or at least repairable.
