An expansion tank protects a home’s hot water system by preventing the buildup of excessive pressure due to thermal expansion. Thermal expansion refers to the characteristic of water to expand when heated, resulting in an increased volume. Without an avenue of escape in a closed hot water system, the pressure due to an increased volume may result in damage to the water heater and the home’s plumbing. If you have experienced problems due to thermal expansion, Benjamin Franklin Plumbing can provide expansion tank installation for your home, and the water heater repair in Sugar Land that you need.

The basic function of an expansion tank is to serve as an overflow receptacle for the expanded hot water, resulting in reduced pressure on the home’s water heater, and plumbing.

Prior to federal legislation requiring backflow preventers to prevent contamination of public water supply from individual homes and businesses with expanded water volume, hot water had the avenue of backing into the home’s plumbing and into the municipal water supply. With a closed hot water system, an expansion tank is required to provide the protection the water heater, and plumbing system need.

The installation of backflow preventers isn’t the only situation where an expansion tank can be beneficial. Any home with a closed hot water system due to a check valve, or a pressure-reducing valve, also need the protection provided by an expansion tank against elevated pressure.

An expansion tank is sized specifically for your home based on the water heater capacity, and incoming water pressure. If you are installing a new water heater, consider the simultaneous installation of an expansion tank. You will benefit with an extended lifespan of the water heater, and will reduce the incidence of leaks and water heater repair in Sugar Land. Our licensed plumbers can accurately determine the proper expansion tank for your home.

Furthermore, warranty requirements for new water heaters may require expansion tank installation. A growing number of manufacturers require an expansion tank in order to maintain the warranty. A licensed plumber will be aware of the code and water heater requirements. Benjamin Franklin Plumbing can provide the expert installation you require.

How it Works

Expanded hot water causes pressure to rise in a closed hot water system, triggering a diaphragm in the expansion tank to retract, and allowing hot water to enter, reducing the pressure within the water heater and pipes. With the pressure reduced, damage is averted, reducing the need for water heater repair in Sugar Land. The water in the expansion tank is later released into the water supply when a tap is opened.

Additional applications when the installation of an expansion tank is recommended include:

  • Water meter replacement
  • Water heater replacement
  • New home construction
  • With the installation of a pressure reducing valve
