What does the Flo-Guard System do?
Flo-Guard System prevents water damage by shutting
off the main water supply to prevent a catastrophe from
occurring. The system can be activated manually with
a special wall switch that comes with the system or automatically
by connecting it to a security or smart home system.
Can water shut-off occur after a delay?
Water shut-off can occur instantly or after a preset
delay of 30 minutes to 16 hours. The system can be wired
so both delayed and instant water shut-off occurs. This
is helpful if someone wants to use the delay feature
most of the time, but also wants an emergency shut-off
What if my irrigation system needs to run after the
water is shut off?
system can be connected to any system that uses water
(irrigation, humidification, sump pump, etc.) so water
can be temporarily turned back on only when it’s
needed. To do this, just connect any of these systems
to the inputs on the Flo-Guard controller per the instructions.
Does the Flo-Guard System use sensors to detect leaks?
The Flo-Guard System does not detect leaks either through
the presence or flow of water. We believe in prevention
rather than cure. Any system that responds after a
leak is sensed is allowing some damage to occur. With
water presence based systems the sensors must be close
to the leak and on level ground. If they aren’t,
there will likely be significant damage. With water flow
based systems there is no way to protect all the pipes
because there is no way to set a threshold low enough
to prevent large leaks and still be able to run existing
systems like water sprinklers.
Where is the system installed?
Flo-Guard System is comprised of 4 basic components;
a low voltage power supply, a controller, a water control
valve and a manual switch. The power supply is plugged
into any 120VAC outlet. The controller is typically located
in a basement/crawl space/etc. or garage (similar to
a security system). The water control valve is installed
near and downstream of the water meter. And the manual
switch is typically installed near the main entry point(s)
of the home/business, or interfaced with your existing
alarm or smart home system.
What systems can be interfaced with the Flo-Guard System?
activation (water off), the Flo-Guard System can
interface with a security or smart home system. Additionally,
for temporary deactivation (water on), the Flo-Guard
System can be interfaced with any number of systems including
irrigation, humidification, siphon sump pump,
hydronic (heating), water softener, and others.
How does the Flo-Guard System connect to my security/alarm
Flo-Guard System can be activated by a relay that is
either a standard or optional part of security systems.
Can the Flo-Guard System activate my security/alarm
The Flo-Guard System can ‘talk to’ a
security system to tell it that any of the temporary
deactivation inputs have been called for. This is helpful
if the system is connected to a low water cut-off sensor
on a hydronic system for water make up. This way service
can be called.
Does the Flo-Guard System have to be programmed?
The Flo-Guard System comes pre set with both one
instant and two 30 minute delay activation inputs.
However, the system can be customized with a programmable
jumper (similar to a garage door opener) for up
to a 16 hour delay.
Is there any concern using the Flo-Guard System with
hard or well water?
The Flo-Guard System uses an industrial quality water
control valve. However, if highly contaminated water
is expected, a pre-screen or wye-strainer is recommended.
The system should also be maintained like any similar
system per the operating instructions.
What types of plumbing failures will the Flo-Guard System protect my home or business from?
activated, the Flo-Guard System prevents any and all
types of plumbing leaks including ruptured hot water
tanks; washing machine, dishwasher, and ice maker connections;
frozen pipes; toilet valves; etc.
How long does it take to install the Flo-Guard System?
the Flo-Guard System can be installed in either new
or retrofit, residential, commercial, and industrial
applications, it’s difficult
to establish an average. A fair estimate is 4 hours
depending on the application.
Who should install the Flo-Guard System?
plumbing portion should be done by a licensed plumber.
However, since the Flo-Guard System uses low voltage
(24 VAC) for control, that portion of the installation
can be done by anyone comfortable with working on wiring.
has differentiated itself from the competition by staying
very close to the plumbing industry for your protection
and consumable water safety. Additionally, many states
require by law that any work done on a potable water
system be done by a licensed plumber.
What happens if there is a power failure?
the event of power loss, the Flo-Guard System has
been designed to close the water control valve as a failsafe
to prevent water damage. The system also has a battery
backup that provides power to the controller for approximately
What if I lose power and I need water?
water control valve has a manual override to open
Can the Flo-Guard System be installed in plastic, galvanized,
or PEX pipes?
The Flo-Guard System can be used with any type of
pipe material using the appropriate plumbing fitting.
What type of warranty does the Flo-Guard System have?
Flo-Guard System has a 2 year warranty.
What sizes of pipe does the Flo-Guard System work
has standard part numbers for ¾”,
1”, 1 ½” and 2” pipes. However,
since the controller is separate from the water control
valve, any size valve operated by 24VAC can be used.
This is especially helpful for commercial or industrial
Do I have to use the manual switch to activate the
The Flo-Guard System can be interfaced with a security
or smart home system so the manual switch can be optional.
By installing the Flo-Guard System, will my insurance
company give me a discount on my insurance premium?
Flo-Guard has designed the system to make any home
or business a lower risk building to insure. However,
you must consult your insurance company to determine
if they offer a discount.
Is maintenance required?
Flo-Guard has designed the system to be maintenance
free by using industrial quality, readily available components.
However, as with any similar system, we recommend that
the system be checked for proper operation on a regular
Can the water control valve and controller be installed
outside of my home or business?
Since the water control valve is separate from the
controller and includes a sealable DIN connector, it
can be installed outside. This is ONLY appropriate if
the valve is not exposed to freezing temperatures. Also,
if desired, we offer an optional NEMA 4/4X enclosure
for installation of the controller outside
How exactly does the Flo-Guard System connect to systems
that need water to operate?
an irrigation system, connect the pump relay output to
the irrigation system input on the Flo-Guard System controller.
This applies to any 24VAC input including humidification,
hydronic, etc. For a siphon powered backup sump pump, install
the optional float switch we offer so it operates at the
same as the main float switch, and connect it to the sump
pump input on the Flo-Guard System controller. This applies
to any dry contact switch input including water softener,
What if I have a high risk area that I still want to
protect with a water sensor?
desired, a self-contained water switch can be connected
to the Flo-Guard System to turn the water off instead
of the manual switch. These are commercially available
24VAC powered devices that are often used in HVAC applications
where condensation levels are a concern.
Does Flo-Guard use full port valves?
We use full port valves. Moreover, since the valve
is separate from the controller, the valve can be sized
to any application where water flow restriction is
a concern. Flo-Guard has four standard valve sizes – ¾”,
1”, 1 ½”, and 2”. For larger
pipe applications we can supply the system without the
valve so it can be specified and purchased separately.
Can more than one manual switch be used?
Multiple switches can be used to activate and deactivate
the system. These can be placed at the main entrances
of the dwelling.
Is there a way to power a remote indicator light in
commercial/industrial applications, or cases where multiple
manual switches are used?
Each manual switch has an integrated, remotely powered
lamp that indicates if the water is on or off. These
lamps are powered by an output on the Flo-Guard controller.
This output can also be used to power any 24VAC remote
indicator or lamp.
