خرطوشة الصرف الصحي 12L De Dietrich 7219217

This 12-liter sanitary cartridge is a key part of a combination boiler's domestic hot water system, regulating flow and temperature for a comfortable supply. Suitable for higher demand households, it helps maintain steady hot water output. If you experience inconsistent water temperature or low flow, a worn cartridge may be the cause. Verify compatibility with your boiler brand and model before replacement.
