Frequently Asked Questions About Water Heater Expansion Tank Installation in Elkins
Most residential expansion tank installations cost $250 to $550 including the tank and labor. Attic installs, larger tanks or a new pressure reducing valve can raise the total to $600 to $1,000.
When water heats up, it expands. Without an expansion tank, this expanded water has nowhere to go, increasing pressure within your closed plumbing system. This constant pressure can quickly wear out water heater components and relief valves and even cause leaks or ruptures. The expansion tank absorbs this excess volume, protecting your whole system.
Yes, expansion tanks need occasional maintenance to keep working correctly. It is a good idea to have the air pressure checked annually to match the incoming water pressure. This preventive check helps extend the life of the tank and your water heater.
We install potable-rated tanks from Watts, Amtrol and A.O. Smith. Each is approved for drinking water and built with corrosion-resistant connections.
GJK Plumbing stands behind our workmanship and the quality of the products we install. We offer a warranty on both the expansion tank itself, per the manufacturer's terms, and our installation labor. Specific warranty details will be explained at the time of service.
Usually, installing a water heater expansion tank takes about 1 to 2 hours. This includes assessment, preparation, installation and testing. Our skilled plumbers work efficiently to minimize any disruption to your hot water supply.
Signs of a failing expansion tank include water dripping from the tank's air valve, rust or corrosion on the tank's exterior or a water heater that frequently cycles on and off. You might also notice fluctuating water pressure or a banging sound in your pipes, which indicates excessive pressure buildup.
A standalone expansion tank usually does not require a permit, but one is often included when it is installed with a new water heater. We follow local requirements on every job.
