Expansion Tank Sizing for Large Water Heaters in Morgantown
A standard 2 gallon tank works for many 40 and 50 gallon heaters at moderate pressure. Larger heaters, higher incoming pressure or high-capacity systems may need a 4.5 gallon tank or larger. We use manufacturer sizing charts that factor in heater volume, supply pressure and temperature setting. Correct sizing keeps the tank from over-flexing and failing early.

New Expansion Tank Installation in Morgantown
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 install a new tank on the cold water supply near the heater using a tee and short nipple. The air side is precharged to match your static pressure, usually between 50 and 70 psi. We then run the heater and watch the gauge to confirm pressure stays steady.
Replacing Old Expansion Tanks in Morgantown
Expansion tanks do not last forever, and an old, waterlogged or corroded tank offers no protection. If your existing tank in Morgantown is showing signs of failure, such as a dripping relief valve or fluctuating water pressure, it is time for a new one. We expertly remove the old unit, dispose of it responsibly and install a new, correctly sized expansion tank. This proactive replacement prevents costly damage to your water heater and plumbing system and restores proper pressure control.
Commercial and Multi-Unit Expansion Tanks in Morgantown
Apartment buildings, restaurants and offices with large commercial water heaters or multiple tanks need larger expansion tanks sized for total system volume.

We schedule work to limit hot water interruption for tenants or customers.

Expansion Tank for Tankless Water Heaters in Morgantown, WV

Frequently Asked Questions About Water Heater Expansion Tank Installation in Morgantown
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 bring the total to $600 to $1,000.
If your home has a pressure reducing valve, check valve or backflow preventer on the main, you likely have a closed system that needs one. Many local codes require it whenever a water heater is installed on a closed system.
Most installations take one to two hours. Attic installs or PRV replacements can add an hour or two.
Manufacturers typically offer one to five year warranties depending on the model. We also warranty our installation labor.
An expansion tank is important in Morgantown because water expands when heated. Without a tank to absorb this expansion, the increased pressure can damage your water heater, pipes and fixtures. West Virginia builds its plumbing standards on the International Plumbing Code, and the state licenses plumbers who do the work. Many local plumbing codes also mandate expansion tanks for safety and system longevity.
A dripping temperature and pressure relief valve frequently means thermal expansion is pushing pressure too high. A failed or missing expansion tank is the most common cause.
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 entire system.
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.
