If your boiler pressure drops overnight but you can’t see any leaks, it’s a strong sign something isn’t right within the heating system.
Pressure loss without visible water usually means water is escaping somewhere within the system.
This is exactly what our Central Heating Leak Detection service is designed to diagnose accurately.
