Plant ID No. 001-4237

Application

The Taco LeakBreaker® is a leak detection and water shutoff
device. It is designed to detect a water leak and shutoff the incom-

ing water supply to a water heater. It is suitable for use with many
other water appliances that have a 3/4" (or smaller) connection
requiring leak protection.

Ease of Installation / Operation

The valve can be installed in either vertical or horizontal piping
and in any direction or orientation. LeakBreaker consists of a
control panel, full port electrically actuated ball valve, floor sensor
and is powered by batteries, AC adaptor or both. The components
are connected with easy to use plug in quick connects. A multi-

function LED on the control module identifies the current state of
the LeakBreaker and aides with troubleshooting.

Valve Installation

Warning: Never place any body parts or objects

into the valve opening, doing so may result in severe
injury!

Caution: Installation should only be performed by qual­ified persons familiar with normal plumbing practices.

These instructions should be considered in addition to
local codes. Consult your local authority regarding any instruc­tions contradictory to code requirements.

Note: Depending on your piping system, additional fittings not
supplied with this product may be required.

3. Install the LeakBreaker valve into the cold water supply to the
water heater.

CAUTION: If using a threaded to sweat adaptor on
the valve installation, the actuator must be removed

from the valve body before soldering (see instructions
for removing actuator). The ball valve must be in the full open
position before soldering.The valve is shipped in the closed
position. Use of a solder with a melting point below 600°F is
recommended. Do not overheat! Make sure the ball valve is in
the FULL OPEN position during soldering. Direct flame tip away

from the center of the valve. Cool valve quickly with a wet cloth.

Actuator Removal and Installation

1. Actuator Removal: Remove the valve actuator prior to solder­ ing by pushing in and holding the release clip at the front of the

actuator and lifting upward approximately 3⁄4" (see Figure D).

1. Shut off the main water supply.

2. Open a fixture nearest the water heater to relieve water pressure.

2.

To re-assemble the actuator to the valve body: Position actu­ator such that the “D” shaped valve stem aligns properly with
the “D” shaped actuator drive cavity. (Note: The “D” shaped
stem design allows for correct insertion every time.) Next, slide
the valve stem into the actuator cavity, push in and hold the
release clip until the actuator slips over the valve locking posts
(see Figure D). Once the actuator is flush to the valve body, let
go of the release clip. Using very little force, try to take the
actuator off of the valve body without using the release clip.
Both locking posts should be firmly attached to the actuator. If
the actuator slides up the stem, repeat the assembly process.

OPEN

1.

Press the tabs on the side of the control panel and pull apart
to separate the front panel from the back panel.

2.

Using the hardware provided mount the back of the control
panel in a location close enough to the water heater so that the
both the actuator and sensor wiring can be connected to the
control panel.

3.

If using batteries install into the battery holder. Be sure to
insert each battery in the correct orientation as indicated in the
battery holder. If electrical power is being used the power cord

may also be connected. LeakBreaker® can be powered by
bat-teries, power supply or both.

4.

Assemble the front on the control panel to the back of the panel.

5.

With screws on the sensor quick connect facing toward the
back of the controller, plug the sensor wiring into the control
panel port marked sensor. Place the sensor on the floor, at the
base of the water heater, making sure it is located where water
is likely to flow. If the water heater is in a pan place the sensor
inside of the pan.

If the sensor is installed in a metal pan or on a damp surface

5a.

insert the 4 feet provided into the 4 holes on the corners of the
sensor. If additional sensors were purchased locate them in
different areas around the water heater.

6.

With the screws on the actuator quick connect facing toward
the back of the controller, plug the acuator wiring into the con­trol panel port marked valve.

3.

NOTE: When attaching the wires to the actuator quick con­nect the black wire must match up to the "B" on the control
and the red wire must match up to the "R" on the control.

The LeakBreaker will not function correctly if it is not
wired correctly.

NOTE: If using multiple sensors break off the tab at the end
(as shown in Note Fig. 5b) on all sensors except for the last
one in the chain. Never remove the tab when using a single
sensor or for the last sensor in the chain. See multiple sen­sor wiring diagram for wiring

Two (2) sets of dry contacts are provided, each set includes
normally open and normally closed connections. They can be
used to send a signal to any device requiring an open or close
signal, such as a security system.

Testing Your Installation

1.

Press the open button on the front panel to open the valve,
watch the indicator on the top of the valve to make sure the
valve rotates to the open position, press the close button to
close the valve and watch the indicator on the top of the valve
to make sure the valve rotates to the closed position.

2.

Close any open fixtures and open any shut-off valves that
were closed during the installation the valve. Make sure there
are no leaks.

3.

With the valve in the open position place the sensor in water.
The valve should close, the LED should flash red and the audi­ble alarm should sound. Once the valve closes press the mute
button to silence the alarm.

4.

To reset the LeakBreaker completely dry off the sensor and
then press the open button.

Congratulations on the successful installation of your
LeakBreaker!
