This thermal expansion tank (TET) has clearly done its job.
Over time, the internal bladder and components inside a thermal expansion tank wear out from absorbing pressure fluctuations caused by water heater expansion. Thatâs exactly what theyâre designed to do.
The good news? Weâd much rather see wear and tear on a replaceable thermal expansion tank than on your water heater, pipes, fittings, or fixtures.
A failed or waterlogged TET can contribute to excessive pressure in your plumbing system, shortening the life of your water heater and other components.
Thatâs why we offer yearly thermal expansion tank calibrations and inspections to verify proper air charge and ensure your TET is still protecting your plumbing system as intended.
A small maintenance visit today can help prevent a much bigger repair tomorrow.
