I installed this system to follow our existing well water treatment system. It is working great so far. My brother in law is a plumber and came over to help (he's got all the tools). We used pro-press copper fittings and at his recommendations we installed a bypass. Copper is quite expensive, with the ball valves and other fittings we used over $300. 00 in parts and pipe. If you pay someone to install it I wouldn't be surprised it cost as much as you paid Express Water for the install.
