Water heater installations and replacements FAQs

You'll need an expansion tank if your home has a closed water system, which is standard in newer homes or those with backflow preventers or pressure regulators. Expanding hot water has nowhere to go in closed systems, creating potentially damaging pressure. The expansion tank provides space for this expanded water, protecting your plumbing system and water heater from premature failure. Many local building codes now require expansion tanks, and some water heater warranties may be voided without one.

For a standard 50-gallon water heater, a two-gallon expansion tank is sufficient. This sizing assumes normal household water pressure between 40 and 60 psi. If your home has higher water pressure (60 to 80 psi), consider upgrading to a slightly larger tank for added protection. The expansion tank's purpose is to accommodate the increased volume that occurs when cold water heats up, which is proportional to your water heater's capacity.

Watch for signs like dripping water around the tank, fluctuating water pressure throughout your home, or unusual noises in your plumbing system. A properly functioning expansion tank should feel light when tapped on the bottom—if it feels heavy or waterlogged, the internal bladder has likely failed. Other indicators include frequent triggering of your temperature and pressure relief valve, visible corrosion on the tank, or unexplained increases in your water bill, suggesting hidden leaks.

Most expansion tanks have a service life of five to 10 years, though some may last up to 12 years or more with proper maintenance. Factors affecting lifespan include water quality, system pressure, installation quality, and tank construction. Hard water areas often see shorter lifespans due to mineral buildup. Regular maintenance checks can help identify potential issues before complete failure. When your water heater is due for replacement, it's wise to replace the expansion tank simultaneously, even if it hasn't failed yet.

A 30-gallon water heater needs an expansion tank if your home has a closed plumbing system. The need for an expansion tank is determined by your plumbing system type rather than water heater size. Even smaller water heaters create thermal expansion when heating water. If your home has a backflow preventer, pressure regulator, or check valve on the main water line, you have a closed system that requires an expansion tank. Check your local plumbing codes, as many jurisdictions now mandate expansion tanks regardless of water heater size.
