I was hoping that people might share ideas on hand held sprayers. Every time I turn around my sprayer needs repair. It will bubble up through the pump. Often the pump will lock up. Some times the line clogs. I know these are all regular maintenance problems but I am tired of the frequency. Most of the problems are from dust and debris that is created on this mowing crew with the blowers. I was thinking to store these sprayers on the trailer or in the truck in a sealed container such as a garbage can that has a lid when they are not in use. Does any one have any thoughts or tips that they have learned as far as hand helds go. Sprayer thoughts out side of these problems are welcome also.
