Thermal expansion refers to the expansion of water when heated. In a closed hot water system, the increased pressure from expansion can cause damage to the water heater and the plumbing system. An expansion tank can prevent the damage due to increased pressure, by serving as an overflow receptacle for expanded hot water. Benjamin Franklin’s plumbers in Arlington can provide the installation you need.

Prior to the new federal regulations requiring the installation of backflow preventers throughout the nation, the extra volume of hot water created by thermal expansion could back up into the home’s water lines, and the municipal water main. Consequently, this relieved the pressure on the home’s plumbing system. However, the installation of backflow preventers and other devices have closed this route off. As a result, many homes are left with a closed hot water system. Not all water systems have installed the devices to date, but there are additional components that also turn your home’s plumbing into a closed system. Pressure regulators, for example, are an additional device that creates the same result.

The Pressure Regulator

Excessive water pressure is an additional source of leaks and damage to the plumbing. Water authorities often set the pressure in excess of 100 psi, and even more than 150 psi. This is to ensure the water needs for fire hydrants, high rises, or structures on a higher elevation. Homes located in areas with high water pressure typically use a pressure regulator on the water supply line to bring it down to a safe level. 

Testing your home’s water pressure is a simple with a water pressure gauge, which screws into an outdoor faucet. When the tap is opened, the gauge provides the amount of water pressure. If your home does not have a pressure regulator, and experiences high water pressure, Benjamin Franklin’s plumbers in Arlington can install one for you. However, if you require a pressure regulator to control high water pressure, the installation of the device creates a closed hot water system. As a result, the installation of an expansion tank is highly recommended.

Hiring a qualified, licensed plumber for the installation of an overflow tank will assure the appropriate sizing and installation that your home needs. Sizing is based on the household’s hot water needs, the capacity of the water heater, and the pressure of the water entering your home. You can rely on the knowledge and professionalism of our plumbers in Arlington.

An additional reason for using licensed plumbers in Arlington for installation, is the plumber’s knowledge of warranty requirements for installation and local code. In addition, the installation of an expansion tank is highly recommended and in some areas, required in the following:

With the installation of a backflow preventer 

With the installation of a water meter replacement
