Step 1. Choose the location of the pump:
The circulation pump can be installed in either the cold water feed or the hot water out from the water heater. Ease of installation is the only consideration when making your decision.
Step 2. Turn off water heater:
Turn off water heater to make sure it does not come on during installation.
Step 3. Turn off water:
Turn off the water to the water heater. In most cases there is a valve located near 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. Cut the water line where the pump is to be installed:
Remove a section of pipe equivalent to the length of the pump and Flow Monitor assembled plus any extra length for required fittings.

Step 6. Orientation of pump and Flow Monitor:
Make sure the arrows on the pump and Flow Monitor are pointing in the direction of flow.
Step 7. Install pump:
Correct installation of the pump can be either horizontal or vertical. Use proper straps for support if necessary.

Step 8. 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 in the direction of water flow. Do not over tighten.
Step 9. Complete connections and turn on water:
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.
Step 10. Connect the Pump Manager and the Flow Monitor:
There are 2 switches that control the speed of the pump and how it works. The first switch is located in the power cord.
Connect the wire from the Flow Monitor to the connector in the electrical wire from the pump. Set rocker switch to the "Auto" setting.
Pump Speed Switch
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.
Step 12. Test pump operation:
Turning on any hot water faucet in the house to start the pump. Turning off the faucet will stop the pump (assuming that the Advanced Bridge Valve has not been installed yet).
Note: If the Advanced Bridge Valve has been installed the pump will continue to run until 95°F water reaches the sink where the Advanced Bridge Valve is installed. The temperature sensor in the Advanced Bridge Valve will shut off and the water will stop flowing (unless a hot water faucet is open).

Advanced Bridge Valve™ Installation
The Advanced Bridge Valve should be installed under the kitchen or bathroom sink at the farthest fixture from the water heater. Branched plumbing systems will need an Advanced Bridge Valve at the end of each line. Additional Advanced Bridge Valves are available at www.FasterHotWater.com.
Note: Do not use Teflon tape or pipe dope on Advanced Bridge Valve connections.
Shut-off Valve Installation:
Return to Top
- Turn off water to the house and drain the water from the pipes.
- Turn off both the hot and cold angle stops (valves) below the sink.
- Disconnect existing hot and cold water supply lines from the shut-off valves and replace shut-off valves with new custom shut-off valves.
- Attach new stainless steel 1/2" x 1/2" supply lines to nipples.
- Attach other end of supply lines to the appropriate "Cold Water In" and "Hot Water In" ports of the Bridge Valve. Tighten finger tight plus a quarter turn with a wrench. Do not over tighten.
- Attach 1/2" x 1/2" standard supply lines to the appropriate "Cold Water Out" and "Hot Water Out" ports of the Bridge Valve. Tighten finger tight plus a quarter turn with a wrench. Do not over tighten.
- Attach other end of standard supply lines to the faucet. Tighten finger tight plus a quarter turn with a wrench. Do not over tighten.
- Leave shut-off valves in the off position and turn the house water back on. Check for leaks.
- Open both the hot water and cold water shut-off valves and check for leaks.
Advanced Bridge Valve™ Operation
The following steps will determine if the Advanced Bridge Valve is operating correctly.
- Close the cold water shut-off valve below the sink.
- Quickly turn the hot water faucet on and then off to activate the pump.
- Open the cold water faucet.
- Water should flow from the faucet until warm water (95°F) reaches the Bridge Valve. The flow should gradually decrease until no water is coming from the faucet at which time the Bridge Valve has closed.
Warning: Risk of electrical shock.
This pump is supplied with a grounding conductor. To reduce the risk of electrical shock, be certain that it is connected only to a properly grounded grounding type receptacle.
The safe operation of this pump requires that it be grounded in accordance with the national Electrical Code and local government regulations.
To activate the
hot water delivery system, simply turn on any hot water faucet in the house and quickly turn it off.
This will start the pump and within a few seconds you will have hot water everywhere in your home. The amount of time that you wait varies from home to home and is dependent on how far the sink is from the water heater, the size of your water pipes and how many turns there are in the water pipes.
