should be set before installing the nut, split ring and “O” Ring. Avoid getting solder flux, primer, and solvent cement on any
part of the “O” Rings, split rings, bypass valve or control valve. If the building’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.

INSTALLING GROUND:
To maintain an electrical ground in metal plumbing of a home’s
cold water piping (such as a copper plumbing system), install a ground clamp or jumper wiring.
NOTE:
If replacing an existing softener, also replace the ground clamps/wire. If removing a
softener, replace the piping with the same type of piping as the original to assure plumbing
integrity and grounding.

DRAIN LINE:
First, be sure that the drain can handle the backwash rate of the system. Solder
joints near the drain must be done prior to connecting the drain line flow control fitting. Leave
at least 6” between the drain line flow control fitting and solder joints. Failure to do this could
cause interior damage to the flow control. Install a 1/2” I.D. flexible plastic tube to the Drain Line Assembly or discard the
tubing nut and use the 3/4” NPT fitting for rigid pipe (recommended). If the backwash rate is greater than 7 gpm, use a 3/4”
drain line. 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. Piping the drain line overhead <10 ft is normally not a problem. Be sure adequate pressure is
available (40-60 psi is recommended). Where the drain empties into an overhead sewer line, a sink-type trap must be used
with appropriate air gap (see drawing). Run drain tube to its discharge point in accordance with plumbing codes. Pay special
attention to codes for air gaps and anti-siphon devices.
CAUTION: Never insert a drain line into a drain, sewer line, or trap. Always allow
an air gap of 1-1/2” or twice the pipe diameter, whichever is greater,
between the drain line and the wastewater to prevent the possibility
of sewage being back-siphoned into the softener.
