Check the home for a pre-plumbed loop to connect the water conditioner. The loop should contain an incoming line and an outlet for draining according to Aqua Technology. A 110-volt outlet must be close by the loop. If this is not present, contact a plumber to have a loop run.
Disconnect the fuel or power source of your water heater. Turn off the water at the main line where it enters the home, then open the lowest and the highest taps until no more water comes out. Disconnect the pipe connecting the inlet and outlet pipes to open the loop.
Add the conditioning media or salt pellets to the tank. Many units come pre-filled with these materials, so check the manual to determine if this step is necessary.
Screw the corresponding bypass valve into the drain outlet on the unit, then use a threaded connector to connect this to the pipe. Solder the connection; do not use pipe tape. If the loop uses PVC pipes, use a pipe glue considered safe for drinking water.
Add the flexible tube that connects the brine valve on the main water conditioner to the brine or media tank, if appropriate. Some units contain both parts in a single unit.
Screw or snap the bypass control onto the inlet valve. Connect the incoming pipe from the loop to the bypass valve with a pipe clamp, then solder to make a strong connection. PVC pipes require the same adhesive as the drain line.
Turn both bypass valves to the bypass or open position. Turn on the water at the main line and watch for leaks at the inlet and outlet pipes. If a leak does occur, use the bypass valve to stop the water and drain the system again to make repairs.
Plug the unit in and turn it on according to the manufacturer's instructions. Turn the water heater back on once you are sure the water conditioning system is operating properly and the pipes are completely refilled.
