6. Install the Pipe Connector (Yoke) to the Bypass Valve
• Connect the raw water pipe to the inlet pipe connection of the
yoke. See Figure 1 for the correct direction of flow. The arrow
molded into bypass valve will indicate the opposite side direction
because it is set up as UP-flow operation.
• Connect the treated water pipe to the outlet pipe connection on
the yoke. See Figure 1 for the correct direction of flow. The arrow
molded into bypass valve will indicate the opposite side direction
because it is set up as UP-flow operation.
• Support all plumbing connected to the yoke; too much weight will
cause a leak.
• Do not point the soldering torch directly at the mineral tank or
control valve. These composite materials will last a lifetime, but
cannot withstand the intense heat from a torch.
• Avoid short connections of pipe between the system outlet and the
water heater inlet. If you can’t avoid a short connection, move the
system to another location. As a last resort, install a heat trap or
check valve. If this causes “water hammer”, install a “water
hammer” suppressor.
• Connect the yoke to the bypass valve .
• Connect the bypass couplers to the QRS head and tighten all
screws.
7. Set the Bypass Valve to Bypass
• Move the bypass valve handles to the bypass position (see figure 1).
The bypass valve handles should be perpendicular to the pipes.
• Bypass any additional equipment that was installed with this
system (if applicable).
Important Note: The bypass valve is not
designed to withstand heat from soldering
or twisting from the attached threaded
connections.

Helpful Tip: Water heaters can sometimes
transmit heat back down the cold water
pipe into the control valve. It may be neces-
sary to install a back-flow prevention
device to prevent this from occurring.

Important Note: Because of UP-flow opera-
tion, the correct flow direction is the oppo-
site of the arrows on the bypass valve.
Because of UP-flow operation, the correct flow direction is the
opposite of the arrows on the bypass valve.
