FAQ

Will it fit my machine?
The 3/8″ thread is universal and fits most professional machines, including Wega. Compare your current fitting with 3/8″ before ordering.
What does a check valve do?
It lets water flow in one direction only and stops it returning towards the pump; it is usually fitted just after the pump to protect it.
How do I know the fitting direction?
The arrow engraved on the body shows the flow direction and must line up with the pump outlet. Fitted the wrong way, no water passes.
What are the signs it needs replacing?
Unstable extraction pressure and knocking or vibration from the pump when it switches off mean the valve is no longer sealing.
How do I order and get it shipped?
Simply request a quote. We ship to Portugal and across Europe.
