Installation and Operating Instructions

WaterQuick Pro II
Hot Water Circulation System

WaterQuick Pro II 
with Built-in Flow Monitor

Bridge Valve

Step 1. Inspect your water heater supply lines:

If the supply lines are old and inflexible they will need to be replaced.

Step 2. Turn off water heater:

Electric - turn off power by either unplugging the water heater or shutting off the appropriate breaker.

Gas, propane or heating oil - turn off water heater and make sure the pilot light is turned off.

Step 3. Turn off water:

Turn off the water to the water heater. In most cases there is a valve located above the water heater on the cold water supply line.

Step 4. Drain the hot water lines:

Turn on any hot water faucet in the house and let it run until the water stops flowing. Leave the faucet on for the duration of the installation. Drain remaining hot water using the hot water spigot on the water heater.

Note: If water continues to flow, check to make sure that the water has been completely turned off. If the valve does not shut off the water flow completely turn off the valve supplying water to the house or at the water meter.

Step 5. Disconnect the hot water supply line:

Unscrew the hot water supply line at the hot water discharge (typically the left supply line).

Note:  The pump and Flow Monitor can be installed on either the cold water pipe going into the water heater or the hot water pipe going out of the water heater.  Make sure that the arrow on the pump and the arrow on the Flow Monitor are pointing in the direction of flow.  See pictures below.

Cold Water Line Installation

Step 6A. Install a 3/4" FIP x FIP fitting (coupling, union or dielectric union - available at any home improvement store):

Wrap Teflon tape or apply pipe dope to male cold water discharge pipe. Carefully thread the 3/4" fitting onto the cold water discharge pipe coming out of the water heater.

Brass Union
Dielectric Union

Step 7A.  Install the Flow Monitor:

Wrap Teflon tape or apply pipe dope to the male threads of the Flow Monitor. Install the Flow Monitor directly into the 3/4" fitting making sure the arrow is pointing down (the direction of water flow).

Note: The Flow Monitor will not work properly if the arrow is pointing up.

Step 8A. Install the pump:

Make sure the gasket is inserted in the female end of the Flow Monitor. Carefully thread the pump into the Flow Monitor with the arrow pointing down (the direction of water flow).

Note:  Do not over tighten.

Note:  Do not use Teflon tape or pipe dope.  

Step 9A. Reconnect hot water supply line and turn on water:

Screw hot water supply line onto the pump. Make sure that a hot water faucet is turned on in the house and then slowly turn the water back on to the water heater. Check for leaks and repair as necessary. Leave the water running until all of the air has been purged from the water pipes. Turn off the faucet.
Continue on to Step 10.

Step 7B.  Install the Pump:

Wrap Teflon tape or apply pipe dope to the male threads on the inlet side of the pump. Install the pump directly into the 3/4" fitting making sure the arrow is pointing up (the direction of water flow).

Note: The pump will not work properly if the arrow is pointing down.

Step 8B. Install the Flow Monitor:

Make sure the gasket is inserted in the female end of the Flow Monitor. Carefully thread the Flow Monitor on to the pump with the arrow pointing up (the direction of water flow).

Note:  Do not over tighten.

Note:  Do not use Teflon tape or pipe dope.  

Step 9B. Reconnect hot water supply line and turn on water:

Screw hot water supply line onto the Flow Monitor.  Make sure that a hot water faucet is turned on in the house and then slowly turn the water back on to the water heater. Check for leaks and repair as necessary. Leave the water running until all of the air has been purged from the water pipes. Turn off the faucet.
Continue on to Step 10.

Step 10. Connect the wire from the Flow Monitor to the pump:

There are 2 toggle switches that controls the speed of the pump and how it works. The first toggle is located in the power cord and contains the connection box that the Flow Monitor wire snaps into.

Connect the wire from the Flow Monitor to the connector in the electrical wire from the pump. Set toggle switch to the Auto setting.

Set pump toggle switch to 3 for the highest speed.

Step 11. Plug the pump in:

Plug the pump into a properly grounded 110 vAC outlet.

Note: Route the cord away from any vents on gas, propane or oil fired water heaters.

Step 12. Test pump operation:

Turn on any hot water faucet in the house to start the pump. Turning off the faucet will stop the pump (assuming that the Bridge Valve has not been installed yet).

Note:  If the Bridge Valve has been installed the pump will continue to run until 95°F water reaches the sink where the Bridge Valve is installed. The temperature sensor in the Bridge Valve will shut off and the water will stop flowing (unless a hot water faucet is open) and the pump will turn off.
