Thermal Expansion Devices in Largo

Complete Protection for Pinellas County Homes & Businesses

Thermal expansion is an issue that affects plumbing systems across the country, but homes in Pinellas County can be especially vulnerable. While many residential buildings are part of the public plumbing system, some are “closed” systems that require extra protection. We want our customers to have all of the necessary information about thermal expansion, the risks associated with it, and what they need to do to protect their homes.

What is Thermal Expansion?

Like many substances, water expands when it’s heated. Water also does not condense much when pressure is applied. This means that, when your water heater is working and the water inside heats up, the volume of the water inside could increase beyond the tank’s capacity. Newer homes and residential buildings are built with protections that prevent this excess water from damaging your plumbing, and the public plumbing network also has protective measures in place. However, some older buildings that have their own closed plumbing systems lack an outlet for excess hot water created by thermal expansion, which can have damaging consequences for your water heater and piping.

Thermal expansion can lead to:

  • Cracks in your water heater
  • Reduced lifespan for pipes & fixtures
  • Dripping faucets
  • And other issues

If you believe that thermal expansion could be a threat to your plumbing, get in touch with our licensed plumbers ASAP. We can let you know if your building’s plumbing system is closed or otherwise vulnerable, and help you install and maintain the necessary precautionary measures.
