Honeywell Home 3-Port Motorised Valve - Resideo - V4073A1062/U

A 3-port valve controls water flow to two different circuits, such as radiators and a hot water cylinder, allowing you to have heating and hot water.

Typically installed near the boiler, the valve directs the flow of hot water to the radiators and/or the hot water cylinder.

With proper maintenance, the valve can last for many years. Regular servicing and checks can extend its lifespan.

While the physical replacement is straightforward, the electrical connections can be complex. For safety, it is recommended to hire a qualified professional to replace the valve.

Common causes include wear and tear, electrical faults, and debris or limescale buildup.

The valve is compatible with fully pumped central heating systems.

You can check the valve by observing its movement when the heating or hot water is turned on and off. Check for any unusual noises or leaks.

Check the electrical connections and ensure the valve is receiving power. Check the thermostat settings to confirm a demand for heat or hot water. If problems persist, the valve may need to be replaced.

Check the valve is operating correctly. Ensure the pump is working. Check the system's other components, such as the boiler.

Check for debris or blockages within the valve. Air in the system can also cause noise; bleed the radiators and check the system pressure.
