So here is a handy idea . I use 3 gallon sprayers a lot . The hand pump type . Age convinced to get creative . I bought tire valves the type with a threaded nut . Drilled a 7/8 hole and installed the valve . So now I just air it up to spray . I watch the stream of spray while airing as you could blow it up I think . Anyway once I have a strong spray that is enough . I use about half then give it more air . Got tired of all that pumping from half empty on .
You get my post of the day award! Put it somewhere where you won't loose it!
