I have a Unidose Uo42-281 pump on my well to add chlorine to my water. I am looking for the spring loaded valve that attaches to the pump. The fitting is the same as the two on the in and out side of the pump except that there is a spring and stop that prevents well water from back feeding into the pump.
the spring has deteriorated and I need to replace it.
Do you carry such an item?
