If your home has a pressure reducing valve and no expansion tank, the water heater is probably seeing a pressure spike every heating cycle.

We then run the heater and watch the gauge to confirm pressure stays steady.

Frequently Asked Questions About Water Heater Expansion Tank Installation in Knoxville
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.
We install potable-rated tanks from Watts, Amtrol and A.O. Smith. Each is approved for drinking water and built with corrosion-resistant connections.
A dripping temperature and pressure relief valve often means thermal expansion is pushing pressure too high. A failed or missing expansion tank is the most common cause.
Permit requirements for expansion tank installation can vary depending on local codes in Knoxville and whether it is part of a larger water heater replacement. Our team at BGV Plumbing is familiar with local regulations and can advise you on any permits needed for your installation.
An expansion tank is important in Knoxville because water expands when heated. Without a tank to absorb this expansion, the increased pressure can damage your water heater, pipes and fixtures. Tennessee adopts the International Plumbing Code at the state level, and many local jurisdictions enforce their own adopted edition with local amendments. Many local plumbing codes also require expansion tanks for safety and system longevity.
While it might seem like a simple task, installing a water heater expansion tank involves working with pressurized water lines and getting the sizing and code compliance right. It is best to hire a licensed plumber for a safe, correct installation that avoids leaks or damage to your system.
A waterlogged tank feels heavy and sounds solid when tapped near the top. Water coming out of the air valve when pressed is a clear sign the bladder has failed.
While less common than with traditional tank water heaters, an expansion tank can still be required or beneficial for tankless water heaters, especially if your home has a closed plumbing system because of a backflow preventer or pressure reducing valve. We will evaluate your setup to provide the best recommendation.
