Cut space in existing pipe wide enough to
accommodate the valve/flowbody.
The Leak Defense System includes a lead-free brass valve
connected to a stainless steel flowbody. This valve/flow-
body assembly is designed to be installed as one unit and
should never be disassembled. If a split-system is needed,
contact us.
The Leak Defense System requires a length of pipe be
removed to accommodate the valve/flowbody assembly
and any connectors. The Leak Defense System valve/
flowbody assembly can accept all common methods
of pipe connections including unions, sweat adapters
threaded pipe, or lead-free brass unions. Dielectric unions
should only be used when connecting galvanized pipe to
our system. Installer is responsible to maintain continuity of
electrical grounding system per local codes.
a. Install using standard unions, sweat adapters, or
threaded pipe.
b. Do not install in prolonged direct sunlight. This causes
water in the valve to heat and the probes will interpret
this as water flow.
c. Make sure the valve has been installed in the orientation
specified on the label (i.e. Vertical Up, Vertical Down,
or Horizontal) with water flowing in the direction of the
arrow on the flow body.
d. Restore water supply.
e. Check for leaks at the valve/flowbody and probe.
STEP 6: Cut a space to accommodate valve/flowbody
STEP 7: Install Leak Defense System valve/flowbody
INSTALLING THE VALVE/FLOWBODY
Critical:
If some form of sweat adapter is used, it is
imperative that heat from the torch does not reach the
valve/flowbody as this may cause permanent damage
to the Leak Defense System unit.
Important:
Bleed air slowly from the piping system
to prevent damage to the Leak Defense System or
to any other plumbing fixtures when water flow is
restored.
WARNING:
Do not place any
tools on the delicate black
portion of this sensor.
