The volute of the pump (silver part) can be installed in either a vertical or horizontal orientation. However the can (blue part) must be installed in a horizontal orientation.

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 Advanced Bridge Valve should be installed under the kitchen or bathroom sink that is the farthest fixture from the water heater. Branched plumbing systems will need an Advanced Bridge Valve at the end of each line. Advanced Bridge Valves are available here:

Note: It is important that you take into consideration how the pump will be supported and where there is access to an electrical outlet.

WaterQuick Tankless can be installed in several different configurations. The circulation pump and Flow Monitor can be installed in either the cold water supply line or in the hot water line going out into the house.

We love tankless water heaters because they are more energy efficient, you will never run out of hot water (when properly sized) and they take up less space.

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.

The orientation of the pump can be changed by unscrewing the 4 hex head bolts (circled in picture) that hold the can and volute together and rotating the can as necessary. The black electrical box with the 3 speed toggle switch does not need to be on top.

Continuously running hot water through an on-demand water heater will void the warranty and quickly wear out the equipment.

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).

Install pump and Flow Monitor into the water line using the appropriate fittings. We suggest using at least one union for ease of assembly.

It takes a lot of energy to heat water instantly and it would not be good to apply that concentrated energy if the water is not moving. Of course water heaters have safety mechanisms built in to prevent this from happening.

Note: Make sure the arrows on the pump and Flow Monitor are pointed in the direction of water flow (into the the water heater on the cold side and away from the water heater on the hot side).

If you install the circulation pump and Flow Monitor in the cold water line it must be located on the pipe that is the sole supply of water for the tankless heater. If it supplies water to any other fixture it may lead to false activation of the pumping system.

The safe operation of this pump requires that it be grounded in accordance with the national Electrical Code and local government regulations.

On-demand water heaters turn on when a hot water faucet is turned on. But before it starts heating the water it must make sure that the water is flowing.

And it needs to be a system that does not operate continuously (continuous operation voids the water heater’s warranty) and that does not keep your water lines hot unless there is a demand for hot water (wastes energy and promotes pinhole leaks).

Turning 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).

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

The pump and Flow Monitor can be installed in the hot water line that comes out of the water heater and goes into the house. It does not need to be located next to the water heater but it needs to be located before the first hot water lateral.

The system you need is WaterQuick Tankless – the only hot water circulation system specifically designed for tankless water heaters.

But in order to get hot water faster without wasting water down the drain you need a circulation system. One that returns the cold water in the hot water line to the water heater and one that has a high speed pump to move the water faster than just water pressure alone can.

How does ahot waterrecirculatingpumpwork

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

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.

One safety feature is to delay turning on the heat until the water has been moving for a few seconds. This adds to the time that hot water takes to get to your faucet.

To activate the WaterQuick Tankless hot water delivery system, simply turn on any hot water faucet in the house and quickly turn it off.

Water is quickly heated by an on-demand water heater when a hot water faucet is turned on but it can still take “forever” to get hot water at your sink or shower.

Home owners that have recently purchased a tankless water heater are surprised that it actually takes longer for the water to reach the faucet than it did with a traditional tank style water heater.
