To install an expansion tank, start by shutting off the water supply and draining the system.

Next, locate the cold-water supply line and locate a suitable spot to install the tank, ensuring it is supported by the brackets according to the manufacturer’s instructions.

After securing the tank, connect it to the cold-water supply line using a tee fitting and make sure to add a shutoff valve.

Then, connect the tank’s air valve to the plumbing system vents or an open pipe, allowing the air to escape.

Once all the connections are secure, turn on the water supply and check for any leaks.

If everything is in order, adjust the air pressure in the tank to match the system’s pressure.

Finally, double-check all the connections and ensure the tank is properly secured before turning the system back on.

This will ensure the expansion tank is properly installed and functioning correctly. 

Distance Between Expansion Tank and Water Heater

The distance between the expansion tank and water heater plays a critical role in performance.

Incorrect placement can affect the effectiveness of the tank in accommodating thermal expansion, potentially leading to increased pressure within the system.

Factors to Consider When Determining the Distance Between the Expansion Tank and the Water Heater

When determining the distance between the expansion tank and the water heater, factors such as:

the water heater’s capacity

system pressure

the specific requirements outlined by the expansion tank manufacturers must be taken into consideration.

Consulting with a professional plumber can further aid in determining the ideal placement.

7 Instructions for a new expansion tank distance from water heater Installation

Water Heater Installation
