FAQ

Where should a hot water recirculating pump be installed?

You can install the circulation pump and Flow Monitor on either the right side of the cold-water supply line to the water heater or on the left side of the hot water supply line that goes from the water heater into your house. This will help in the efficient distribution of water throughout your home.

How to install a Grundfos recirculation pump?

To properly install the pump onto the water heater discharge, use the 3/4″ female fitting and gasket provided with the pump. Make sure the pump shaft is positioned horizontally. It is important to install the pump in a way that it pumps water away from the hot water heater and towards the house.

What size should a hot water recirculation line be?

The speed at which water flows is crucial for the pipes and valves in domestic hot water systems that use copper piping and brass or copper alloy valves. When hot water is combined with high water velocities, it can lead to erosion problems for the walls of the pipes and valves. To mitigate this, I always make sure to use a minimum pipe size of ¾-inch for the hot water return system piping.

Is an expansion tank required for a recirculating pump?

To ensure the proper functioning of a closed-loop recirculating system, it is necessary to have an expansion tank. This tank can be obtained from a local plumbing supplier and should be connected to the cold water supply line in close proximity to the water heater. Inside the expansion tank, there is a bladder and an air charge, both of which play important roles in the system.
