Prevent Plumbing Damage with a Properly Installed Expansion Tank

An expansion tank is a small but crucial part of your home’s plumbing system, designed to protect your water heater and pipes from excess pressure buildup. Without one, you risk water leaks, pipe bursts, and premature water heater failure.

At AdvantaServ, we provide professional expansion tank installation, repair, and maintenance to ensure your plumbing system stays safe and efficient.

What is an Expansion Tank & Why Do You Need One?

A water heater expansion tank absorbs excess pressure caused by heated water expanding inside your plumbing system.

  • Prevents water heater damage due to excessive pressure
  • Reduces stress on pipes, valves, and fixtures
  • Maintains consistent water pressure throughout your home
  • Required by plumbing codes in many areas

If your home has a closed plumbing system, an expansion tank is a must-have to prevent water hammer and pressure spikes.
