🔌 Function

Allows flow in one direction only, so the system it serves cannot drain back or feed the wrong way.

⚠️ Common Signs of Failure

• Fluid or pressure draining back when the system is shut down, so it has to be primed or bled again before it will run
• Loss of pressure or flow in the circuit the valve serves, or the system taking far longer than normal to build pressure
• A valve that rattles, buzzes or leaks past its seat, or weeps at its connections
• Air being drawn into the system, showing as bubbles, foaming or erratic running

🛠️ Service Notes

• Note which way round the valve sits before removing it and fit the replacement the same way — a non-return valve installed backwards will block flow entirely or allow the drain-back it was there to prevent
• Work clean and fit new sealing washers or O-rings on the connections; a small amount of debris is enough to hold a check valve off its seat
• Check the new valve moves freely and seals in the reverse direction before fitting, and blow or flow test it in the correct direction if you are unsure of its orientation
• Hold the valve by its hex or flats when tightening, never by clamping the body, and tighten to the figure given in the workshop manual for your engine
• Run the system afterwards and confirm the symptom has gone as well as that the joints are dry
