Step-by-Step Guide to Installing a Recirculating Pump on a Tankless Water Heater

How to Install Recirculating Pump on Tankless Water Heater

Installing a recirculating pump on a tankless water heater is a great way to improve the efficiency and convenience of your hot water system. This article will guide you through the steps to install a recirculating pump on your tankless water heater, ensuring that you have hot water at the tap whenever you need it.

1. Gather the Necessary Tools and Materials

Before you begin the installation process, make sure you have all the necessary tools and materials. These include a recirculating pump, pipe cutters, T-fittings, unions, and plumber’s tape. You may also need a screwdriver, adjustable wrench, and a level.

2. Turn Off the Power and Water Supply

Safety should always be your top priority. Before you start the installation, turn off the power to the tankless water heater and close the main water supply valve. This will prevent any accidents or damage during the installation process.

3. Locate the Best Installation Point

Choose a location for the recirculating pump that is close to the tankless water heater and easily accessible. It should be mounted on a stable surface, such as a wall or floor.

4. Cut the Pipe

Using a pipe cutter, cut the hot water supply pipe where you want to install the pump. Make sure to cut the pipe at a 90-degree angle for a clean and secure connection.

5. Install the T-Fittings and Unions

Attach a T-fitting to each end of the cut pipe. Then, connect the unions to the T-fittings. These unions will allow you to easily disconnect the pump for maintenance or repairs.

6. Connect the Recirculating Pump

Connect the pump to the unions on the T-fittings. Make sure the pump is oriented correctly and that the arrows on the pump indicate the flow direction.

7. Secure the Pump

Mount the pump to the chosen location using the provided brackets and screws. Ensure that the pump is level and securely fastened to the surface.

8. Connect the Pump to the Power Supply

Plug the pump into a GFCI-protected outlet. This will prevent any electrical hazards during operation.

9. Test the System

Turn on the main water supply valve and the power to the tankless water heater. Run hot water from a tap to check if the recirculating pump is working correctly. The water should flow smoothly and reach the desired temperature.

10. Adjust the Temperature and Flow Rate

If necessary, adjust the temperature and flow rate settings on the recirculating pump to optimize its performance. This may involve adjusting the pump’s speed or changing the settings on the tankless water heater.

By following these steps, you can successfully install a recirculating pump on your tankless water heater. This will provide you with a more efficient and convenient hot water system, saving you time and energy in the long run.
