When assembling the installation tting package (inlet and outlet),
connect the tting to the plumbing system rst and then attach the nut,
split ring and o-ring. Heat from soldering or solvent cements may dam-
age the nut, split ring or o-ring. Solder joints should be cool and solvent
cements should be set before installing the nut, split ring and o-ring.
Avoid getting solder ux, primer, and solvent cement on any part of the
o-rings, bypass valve or control valve. If thebuilding’s electrical system is
grounded to the
plumbing, install a copper grounding strap from the inlet to the outlet
pipe. Plumbing must be done in accordance with all applicable local
codes.
5. DRAIN LINE: First, be sure that the drain can handle the backwash
rate of the system. Solder joints near the drain, (if copper is used) must
be done prior to connecting the drain line ow control tting. Leave at
least 6” between the drain ow control tting and solder joints. Failure
to do this could cause interior damage to the ow control. Install a ½”
PVC pipe to the drain line, lawn or garden. Be sure you use ¾” female
adapter, then ½ “ PVC.
Assembly or discard the tubing nut and use ½” pvc. Where the drain line
is elevated but empties into a drain below the level of the control valve,
form a 7” loop at the discharge end of the line so that the bottom of the
loop is level with the drain connection on the control valve. This will
provide an adequate anti-siphon trap. Where the drain empties into an
overhead sewer line, a sink-type trap must be used. Run drain tube to its
discharge point in accordance with plumbing codes.
Pay special attention to codes for air gaps and anti-siphon devices.
**Must be backushed prior to system being put “in service”.
Bypass Valve
The bypass valve is typically used to isolate the control valve from the
plumbing system’s water pressure in order to perform control valve
repairs or maintenance. The WSI bypass valve is particularly unique
in the water treatment industry due to its versatility and state of the art
design features. The 1” full ow bypass valve incorporates four positions
including a diagnostic position that allows service personnel to work on
a pressurized system while still providing untreated bypass water to the
residence. It’s completely all plastic, non-metallic design allows for easy
access and serviceability without the need for tools.
The bypass body and rotors are glass lled Noryl and the nuts and caps
are glass lled polypropylene. All seals are self-lubricating EPDM to help
