💡 What is an expansion tank and why does it matter for hot water systems?

In short, expansion tanks absorb pressure changes as water heats, protecting the system from overpressure and reducing pump cycling.

- Pressure regulation - Precharge and sizing matter - EPDM diaphragm for potable water - Reduces pump cycling and T&P valve trips ✝️
