Preparation
Step 4 instructs you to install the LeakSmart Valve (3/4" FIP x 3/4" MIP) between the rigid water line
coming o the manual cold water valve and the water heater. Most rigid lines will be copper. Evaluate
your line and determine which size adapter you will need (the most common one will be 3/4"
solder x 3/4" MIP). Then determine what size union you will need between the LeakSmart Valve and the
place of a union.
CAUTION: Make sure the LeakSmart Valve is not connected to the adaptor when soldering.
WARNING:
- For use with water only.
- Do not install on gas line.
STOP: You may need to purchase additional to install the LeakSmart Valve.
If you are not sure how to install the LeakSmart Valve to your existing water line, we
recommend that you contact a licensed Plumber.

heater pan, make sure you leave the paper sleeve on. If
the Leak Sensor makes contact with metal, it will signal
the LeakSmart Valve to shut o. The paper sleeve acts as
a barrier between the Leak Sensor and the metal. When
the paper sleeve becomes wet, it will signal the LeakSmart

It is UL US Listed, indicating compliance with safety standards.

Function Description:

The system operates by detecting water leaks and then automatically closing a motorized ball valve to stop the flow of water to the water heater. This prevents continuous water flow from the supply line, although some water already in the water heater may still leak out. The system includes a battery backup to ensure continued operation during power outages.

  • Valve Type: Motorized Brass Ball Valve (3/4" Male x 3/4" MIP)
  • Power: AC Adaptor with battery backup (4 fresh alkaline AA batteries, not included)
  • Leak Sensor: Comes with a paper sleeve to prevent false alarms when placed in a metal water heater pan.
  • Valve Installation: Designed to be installed between the rigid water line coming from the manual cold water valve and the water heater, within 2 feet of the water heater.
  • Control Panel Installation: Mountable within 30 inches of the LeakSmart Valve using screws and a hook & loop mounting pad.
  • Connectivity: Wired connections for the LeakSmart Valve, Leak Sensor, and AC Adaptor to the Control Panel.

Usage Features:

  • Easy-to-read, lighted function buttons: For clear indication of system status.
  • Automatic shut-off: The valve automatically closes when a leak is detected.
  • Manual valve control: The valve can be opened and closed with the touch of a button on the Control Panel.
  • Audible alarm: Activates when a leak is detected, with a button to silence it.
  • Reset and reuse: The system can be reset and reused continuously after a leak event.
  • Testing capability: The system can be tested at any time with the touch of a button.
  • Expandability: Accommodates additional water leak sensors (LeakSmart Water Leak Sensor, Model # 8820700) for broader protection.
  • Battery Backup: Ensures continued operation during power outages. A low battery indicator light and beep signal when batteries need replacement.

Maintenance Features:

  • Automatic maintenance cycling: The valve periodically cycles to ensure reliable operation.
  • Battery replacement: Batteries should be replaced once a year or sooner as necessary, indicated by a flashing red low battery light and a beep.
