If not one has tired it, which I'm sure they have, I did today, and what a snap. The PEX fittings are very easy to work with. Also, right from the city connection, I was able just to unscrew the pex elbow and add my new lengths of pipe. I now have the filter installed in the under storage on the side wall, easy to access, and piped to everything, weather I fill the tank or use pressurized water.
