The Neo-Pure Thermal Expansion tanks are designed for residential water heater and hot water storage tank systems to manage the increased water volume caused by thermal expansion. By maintaining consistent pressure throughout the water supply system, these tanks help protect against over-pressure conditions and extend the life of the system. A durable internal membrane separates air and water, ensuring reliable performance over time. Thermal Expansion Tanks are the perfect solution for protecting your appliances, water heater, and fixtures.

Features
  • Protects the water heater and plumbing fixtures from premature failure
  • Prevents pressure build up within the system
