Bests & Worsts Reviews from Amazon

I have been using this for a year now, and have changed filter element 20 times with no problems. It's made sturdy and has metal threaded inserts 3/4 npt . In bypass mode water flows strait thru the upper housing so it don't come in contact with sediment from a plugged filter. I use Purenex 5 Micron 10-Inch by 2.5-Inch Sediment Filter Cartridges. I have included pics before and after filter change. When changing filter I just place new filter cartridge in the clear lower part and slowly tighten so the filter don't get off center. I only tighten it by hand , If you tighten to much it's harder to get it loose next filter change. I have never had any leaks so far I'm running 80psi on the water line.We sometime have all three showers and washing machine going at the same time, cant tell any difference in pressure drop on a new cartridge and only about 5 psi drop across filter when it gets dirty like in the pic with all the showers and washer filling up. I have pressure gages before and after filter. great product ,bought it here on amazon. package did not say what country it was made in.The pic shows the size of the ports in the inner valve just a little smaller than a dime.
