I took apart the flash turbo sprayer made and offered by this company. Many parts seemed foreign to me. I contacted Valley Industries and Adam Leyendecker immediately sent me an exploded diagram of both the presaent model and an older model which I bought. We have a small, organic pecan farm in Hatch NM. In today's environment of sell it and forget it, I would like to commend this company for service above and beyond the average. Its management must be top notch!
