Water Line Connection
A bypass valve system is included and will be installed on all
water conditioning systems. Bypass valves isolate the softener
from the water system and allow unconditioned water to be
used. Service or routine maintenance procedures may also
require that the system is bypassed.
IMPORTANT: The bypass valve is shipped to you in the bypass
position (Figure 9 Series 360 Bypass Operation). When the
valve is in bypass water will not enter the softening tank. The
water in the building will not be treated. Figure 9 Series 360
Bypass Operation, shows the handles in the service position.
Once you have selected your location check the direction of
the water flow in the main pipe. Figure 9 Series 360 Bypass
Operation can be used to plan the new plumbing assembly.
Inspect the main water pipe. Write down the type of pipe
(copper, plastic, galvanized etc.). Record the size of the pipe.
Plastic style pipes usually have the size printed on the outside.
Other pipes can be measured for the outside diameter and
converted into the pipe size at the store. Do not use pipe that is
smaller than the main water pipe.
The bypass requires two connector fittings that connect to
the plumbing. Size to be determined for specific installation
requirements.
If the main plumbing is galvanized pipe and you are installing
copper pipe, then you must use dielectric insulating connectors
between the two styles of pipe.
Place the tank in position. The design of the tank does not
allow for bad alignment of the connections. You may ask your
supply store about flexible connections.
Take measurements and create a drawing of your installation.
Include pipe lengths and elbows that are needed. If the water
flow is from right to left you will need to cross the plumbing to
the softener. Take the drawing to your plumbing supply store.
Consult with their expert for installation ideas and suggestions.
Assemble the plumbing.
If pipes will be sweat soldered, do not connect
adapters to the bypass until the pipes have
cooled.

The inlet water must be connected to the inlet
port of the valve. When replacing
an existing system, it is possible that the inlet
and outlet plumbing is installed in a reverse
position. Be certain the inlet connection on the
valve is connected to the incoming water fitting
from the water supply.
Do not use petroleum grease on gaskets when
connecting bypass plumbing. Use only 100%
silicone grease products when installing any
plastic valve. Non-silicone grease may cause
plastic components to fail over time.
The bypass assembly connects to the water system by means
of a connector assembly. The connector is secured to the
plumbing and then inserted into the bypass. A clip is used to
hold it in place.
Figure 10 Connector Assembly
Before inserting the connector:
• Check that all O-rings are in place and not damaged.
• Lubricate O-rings and sliding surfaces with 100% silicone.
Firmly insert connector into bypass. Press locking clip into
position. Make certain the clip is fully engaged.
