Installation Instructions
1. If your hot water tank is electric, turn off the power to it to avoid damage to the element
in the tank.
2. If you have a private well, turn the power off to the pump and then shut off the main wa-
ter shut off valve. If you have municipal water, simply shut off the main valve. Go to the
faucet, (preferably on the lowest floor of the house) turn on the cold water until all pres-
sure is relieved and the flow of water stops.
3. Locate the filter system close to a drain where the system will be installed. The surface
should be clean and level.
4. Connect the inlet and outlet of the filter using appropriate fittings. Perform all plumbing
according to local plumbing codes.
ON COPPER PLUMBING SYSTEMS BE SURE TO INSTALL A GROUNDING
WIRE BETWEEN THE INLET AND OUTLET PIPING TO MAINTAIN GROUND-
ING.
Any solder joints being soldered near the valve must be done before connecting any piping
to the valve. Always leave at least 6" (152 mm) between the control valve and joints being
soldered when soldering pipes that are connected to the valve. Failure to do this could
cause damage to the valve.
The US Water Dual Superfilter is equipped with 1” removable connectors. It is recommend-
ed that these connectors are installed in the plumbing fitting using Teflon tape then lubri-
cate the o-ring on the connector remove the red clips and push them into the bypass valve
once they are tight in the plumbing fitting. The red clips can then be re-installed to secure
the connectors in the bypass valve.
The inlet and outlet can be identified on the bypass valve. There are arrows stamped in the
bypass valve showing flow (See page 18 diagram). The arrow pointing toward the valve is
the inlet and the arrow pointing away from the valve is the outlet.
All piping should be secured to prevent stress on the bypass valve and connectors.
