TEFLON® TAPE IS THE ONLY SEALANT TO BE
USED ON THE 1” NPT CONNECTOR YOKES AND
DRAIN FITTINGS.
The system’s control valve is connected to your
incoming and outgoing water lines by way of a
bypass assembly with 1”NPT threaded fittings.
This assembly is composed of the bypass valve and two 1”NPT connector yokes. A flow
restrictor is attached to the outlet connector yoke. Locate the inlet and outlet ports on the
back of the control valve. Note that the inlet and outlet are marked with arrows indicating
the correct direction of water flow. When you are looking at the back of the control valve, the
inlet is on the left and the outlet is on the right. Check the corresponding markings on the
bypass to ensure the correct direction of water flow and attach the bypass valve to the
control valve. The in and out arrows on the bypass should be pointing the same direction as
the in and out arrows on the outside of the control valve.
BE VERY CAREFUL TO MAKE SURE YOU PLUMB THE SYSTEM IN THE RIGHT DIRECTION.
The bypass assembly is secured to the control valve using threaded fittings. Thread sealant
tape should not be used on these threads. The seal is made by way of o-rings. To attach
the bypass to the control valve, simply thread the 2 nuts on the bypass onto the valve until
the nuts bottom out on the valve body. Do not overtighten - it is normal for some “play” to
exist when the bypass assembly is properly seated. This allows for minor misalignment of
