Description

Vaillant Pressure Relief Valve PRV 178985 – New Compatible

The Vaillant pressure relief valve 178985 is fitted across a wide range of Vaillant Ecofit, Ecotec Plus, Ecotec Pro and Sustain boilers. A faulty PRV can cause pressure loss, constant discharge through the overflow pipe, or repeated boiler lockouts.

Replacing a worn or leaking PRV restores correct system pressure control and prevents unnecessary water loss. This new compatible valve is precision-engineered to ensure correct opening pressure and dependable long-term performance.

Installation should always be carried out by a Gas Safe registered engineer.
