Boiler Safety Relief Valve (1/4" MBSP 1.8 Bar)
This is the primary pressure-relief mechanism. Over time, the internal spring can lose its K-factor (spring rate) due to constant thermal expansion and contraction, or mineral deposits can pit the internal seal, causing a continuous steam leak that prevents the boiler from reaching its set TCA pressure point.

Vacuum Breaker Valve (Anti-Vacuum)
Frequently confused with the safety valve, this component is designed to remain open until steam pressure forces it shut. If it fails to seal (due to a hardened O-ring or scale), it will cause constant 'hissing' and water loss into the drip tray or machine interior, mimicking a safety valve failure.

Copper Boiler Gasket Kit
When replacing boiler-mounted valves, the existing copper crush washers or Teflon gaskets often fail to re-seal due to work-hardening. Replacing the interface seal is necessary to ensure a leak-free installation under high-pressure steam conditions.
