Stainless steel connections resist corrosion from hard or aggressive water. We avoid tanks designed only for hydronic heating, since they are not approved for drinking water.

Frequently Asked Questions About Water Heater Expansion Tank Installation in Bristol
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.
Permit requirements for expansion tank installation can vary depending on local codes in Bristol and whether it is part of a larger water heater replacement. Our team at GLV Plumbing knows local regulations and can advise you on any permits needed for your installation.
An expansion tank is important in Bristol because water expands when heated. Without a tank to absorb this expansion, the increased pressure can damage your water heater, pipes and fixtures. Permits and inspections are typically required for water heater replacements, boilers, repiping, and sewer or septic work. Many local plumbing codes also mandate expansion tanks for safety and system longevity.
We install potable-rated tanks from Watts, Amtrol and A.O. Smith. Each is approved for drinking water and built with corrosion-resistant connections.
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.
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 prematurely 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, GLV Plumbing stands behind our work. We offer warranties on both the expansion tank itself, per the manufacturer's terms, and our installation labor. Specific warranty details will be explained during your consultation, so you can have confidence in our service.
