The Leak Defense System valve must be installed on the
main water line and downstream of the primary shut-off
valve, pressure regulator, irrigation line and fire sprinkler
line.
Typical location of the Leak Defense System valve instal-
lation will be in a garage, basement or crawl space. If the
home is on a concrete slab, the valve can be installed in
the garage or before water enters the home. In the latter
case, the valve should be located at least 18” above
grade. It must be protected from direct sun exposure,
moisture and freezing conditions.
Other important considerations include:
Other important considerations include:
a. Install the valve in an accessible location allowing easy
access for proper installation and maintenance
b. Some water utilities require the valve be a minimum of
18” downstream of the water utility meter
c. If possible, install the valve downstream of a manual
shut off valve to allow for easier maintenance
d. A bypass around the valve is not required but may
be recommended
e. Bracing may be required if your plumbing system is
unable to support the weight.
STEP 3: Determining the valve location for the Leak Defense System
IMPORTANT:

accommodate your unique piping configuration and ensure no water inside the premises goes unmonitored.

IMPORTANT:
The valve cannot be installed where it may be submerged in water or exposed to moisture or freezing
conditions. An appropriate insulated or water proof box should be installed to protect the Leak Defense System.
Note:
If there is a fire sprinkler and/or irrigation system that branches off the building supply downstream of the
utility meter, the Leak Defense System valve must be installed on the building supply downstream of the fire
sprinkler, and if possible, irrigation supply branch. In no instance may the Leak Defense System be installed in a
way that it will interfere with the fire sprinkler system.
Note:
The Leak Defense System sees water flowing, but does not differentiate between flow direction (flow in vs.
out). As water main pressures fluctuate, there may be a slight flow out of the home/office which will be seen as
flow. A backflow preventer valve (spring check valve) is recommended to remedy this. This backflow will usually
only be an intermittent or sporadic event, while a leak will have continuous water movement.
