If this does not fix the problem then the air cylinder on the Dupree valve may need new o rings and lubrication. Remember the air cylinder stays under pressure to keep it closed and open

this is on his curb side dump. i for one have never used the curb side dump on either newell. and when my valve started leaking i just took it out and plugged it up.
cant see that i will ever use it. i think that is what bill is going to do.
that said, it is just time before the same valve will go bad on the one he really does use on the drivers side.
