How To: Replace An Expansion Tank With The Thermal Expansion Relief Valve

A more reliable way to handle thermal expansion.

A new water heater solution, SharkBite's Thermal Expansion Relief Valve can replace a water heater expansion tank because it functions similarly. Both products absorb the excess pressure in the plumbing system created by thermal expansion.

Instead of storing water like an expansion tank, the Thermal Expansion Relief Valve releases it, solving common problems pros see when replacing expansion tanks.
