Frequently Asked Questions About Water Heater Expansion Tank Installation in Myrtle Beach
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.
A standalone expansion tank generally 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.
Most standard water heater expansion tank installations can be finished within 1 to 2 hours. More complex installations, or those requiring significant pipe changes, might take a bit longer. Our plumbers work efficiently to limit disruption to your home.
Most expansion tanks last 5 to 10 years. Hard water and high pressure can cut that life, so we check them during water heater service.
An expansion tank is essential in closed plumbing systems to absorb the increased water volume and pressure that occur when water is heated. Without it, thermal expansion can damage your water heater, pipes and fixtures, leading to leaks and premature system failure. Many local codes in South Carolina call for them.
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.
We install potable-rated tanks from Watts, Amtrol and A.O. Smith. Each is approved for drinking water and made with corrosion-resistant connections.
KBN Plumbing installs high-quality expansion tanks from reputable brands like Watts, Amtrol and Zurn. We select brands known for durability and performance so your system gets the best protection. Our plumbers can recommend the best option for your water heater and plumbing setup.
