Main Diverter Valve Motor Cartridge 720003100 I 248733

Main Diverter Valve Motor Cartridge (720003100 / 248733) The Main Diverter Valve Cartridge is the critical internal component used to switch the boiler's output between central heating and domestic hot water. When the tap is turned on, the diverter motor moves this cartridge to close the heating circuit and open the flow to the plate heat exchanger. This part is a high-quality replacement for part numbers 720003100 and 248733, designed to restore full functionality to your boiler's hydraulic system. Seamless Flow Control: Ensures immediate hot water delivery by accurately diverting primary water flow. Leak-Proof Performance: Constructed with high-grade internal seals to withstand constant thermal cycling and system pressure. Efficient Maintenance: Replacing only the internal cartridge is a cost-effective alternative to replacing the entire brass manifold body. System Reliability: Engineered to resist debris and limescale buildup, common causes of sticking or "let-by" issues.
