Non-return valve for submerged water pumps for caravans, motorhomes and campers.

This non-return valve is different from other models since it is intended to be connected directly to the water pumps that are provided for it.

The part that connects to the water rubber is for 12 mm inner rubbers, although it would also be possible to connect to 10 mm water rubbers, either by heating the rubber or by cutting down with a file that part of the valve to be connected since it has a fairly thick plastic thickness and that would allow for that possibility.

The part that connects to the water pump has an interior of 11 mm.
