Rating: 3.7 (6 reviews)

3.7(6 reviews)

Designed for installation on hot water systems to protect against thermal expansion. All WTTA tanks are ASME fixed bladder type for commercial and industrial applications. When system pressure increases due to thermal expansion, water enters the tank’s bladder which expands into the pre-charge air chamber, keeping system pressure below the relief valve setting. Conforms to all lead-free requirements and acceptable for use on drinking water systems.
