Why Replace Your Boiler O-Ring?

A worn or hardened boiler O-ring causes water and steam leaks around the boiler flange, leading to pressure loss, inconsistent extraction, and potential damage to internal components. Replacing it is one of the most effective maintenance steps for restoring a leaking Silvia to full working order.
