Art. No. 30021 one-way check valve for soft pipes
Item corresponds to the description, well-made, functional, with good sealing and adaptability to different diameters, allowing for easy connection. The valve works well the first time it's used, but in my case it needs to be used on the booster pump suction line to completely empty the bilge. At this time, since it's used in a brackish environment and with dirty water, I can't assess its durability and function over time.
