Frequently Asked Questions
How does the water stop function work?
The coupling contains a spring-loaded internal valve that automatically closes when the downstream hose or accessory is disconnected, stopping water flow instantly. When you reconnect, the valve opens automatically to restore flow.
Does this coupling work with saltwater systems?
Yes. The PVC body and internal components are corrosion-resistant and suitable for both freshwater and saltwater applications. Rinse with freshwater after saltwater use to maximize service life.
Can this be used as a standard coupling without the stop feature?
The water stop feature is always active — it is the primary function of this coupling. If you need a coupling without the stop valve, consider IMPA 350901 (standard 13mm coupling).
What maintenance is required?
Minimal maintenance is needed. Periodically rinse with freshwater and check that the internal valve moves freely. The PVC construction resists buildup from most water conditions.
