Potable Water Expansion Tanks
Designed for pressure control in potable water systems, ensuring the safety and stability of your home's water.
The tank uses compressed air to maintain system pressures by accepting and expelling the changing volume of water as it heats and cools. It prevents the water heater pressure relief valve from opening, saves energy, and eliminates a potential safety hazard.
Key Benefits and Functions
- Eliminates the waste of energy and water, thus saving money.
- Protects the water heater and plumbing fixtures from premature failure.
- Reduces potential safety hazards associated with thermal expansion.
- Prevents a dangerous pressure build-up in the system.
