A strong expansion tank are installed in your home’s hot water system to prevent the buildup of excessive pressure within a conventional hot water heater caused by the thermal expansion of hot water. An expansion tank will protect your water heater, hot water lines and fittings from elevated pressure, by acting as an overflow receptacle. The installation of an expansion tank is best left to qualified plumbers in Houston to ensure proper installation.
Water expands when it is heated, a process called thermal expansion. As water will not compress, the extra volume of water must go somewhere. An expansion tank allows this excess volume to flow into it, rather than placing your water heater, pipes fittings and home at risk.
During the times when no hot water is used, the pressure can continue to build and increases the risk of water heater rupture, a burst hot water line or fitting. An expansion tank removes these risks, and consequently the risk of damage to your home and its foundation by allowing hot water to flow into the expansion tank, thereby reducing pressure.
Recent federal regulations requiring backflow preventers to be installed further reduce the avenues of escape for the extra volume of hot water. Consequently, expansion tanks are being recommended and in some cases, required for homeowners across the nation. Benjamin Franklin Plumbing provides plumbers in Houston specializing in the installation and repair of expansion tanks.
Expansion tanks contain a special rubber bladder. When the hot water heater turns on, the water within the home’s piping begins to expand. The expanding water enters the expansion tank. Eventually, hot water is drawn from the system through a tap and the expansion tank releases the extra water into the piping system.
Expansion tanks must be individually sized for your home’s requirements. The size required will depend upon the capacity of your home’s water heater, and the water pressure of water entering your home.
As water utility suppliers nationwide upgrade water systems to conform to the law, many local codes are likely to change. Current recommendations regarding the installation of an expansion tank are in the following situations:
- The replacement of a water meter with a dual backflow valve.
- After the replacement of a hot water heater.
- With new home construction.
- When a backflow prevention device is installed on the water meter or a pressure reducing valve is installed on the service line.
- With the installation of a new pressure regulating valve.
To protect your hot water system and your home from the damaging effects of thermal expansion, the installation of an expansion tank by a qualified plumber in Houston is the safest course for a homeowner to take.
