TW Series Expansion Tank for Potable Water

Many of today’s water systems require backflow prevention. This seals off the system and requires the use of an expansion tank, or the relief valve can discharge on every heating cycle. TW Series tanks eliminate wasting water and provide a smooth operating system, and assure long trouble-free service.
