My faucet stopped pulling water from the jug under the sink. I'm pretty sure that the rubber piston ring is worn out. The faucet is made by Free-flow Products. Is this unit standard on the 26S? Mine is a 1992 model. Does anyone know where to find parts for it? I am having trouble locating it. I don't really want to replace the whole thing if I don't have to, it would probably mean drilling more holes. Thanks.
