    My sprayer nozzles continue to drip after I cut it off. Is their some kind of value or diaphragm that can be installed to stop this. It has gotten worse sent I lengthened the line from the tank to the boom and I know its the left over chemical in the line.

    Get a nozzle body with a check valve. They are a must. Hypro has them. Most farm supply stores carry them.

    Or use strainers with a check valves inside of the screen assembly. If you do that, your spraying pressure needs to be 5 PSI or whatever the spring rating is higher to get past the spring loaded ball. Teejet also makes nozzle bodies with diaphragm check valves or the strainers with check valves.

    Its a Fimco, so I know I need the valve body, I'm sure it does not come with it

    Actually they do not. The nozzle body is separate from the nozzle. The nozzle body has the diaphragm. Spray pressure needs to exceed 5 psi before they open. I did not have any luck with the strainers.
