Description

Small, spring-loaded ball check valve especially for drinking water hand pumps.
The valves are installed directly in the suction hose (13 mm), as close as possible to the tank.

It makes sense to install the valve if there is a problem with backflow into the fresh water tank and water has to be pumped for a long time until it flows out of the tap.

Cannot be used in pressurised water and bilge pump systems.
