For those of you not fortunate to have full spray line circulation, has anyone converted there spray line end caps to either a ball valve tap or anything else to make cleaning built up residual in the end caps easier? I have 8 end caps on my sprayer which are held on by metal forks but are a bit of a pain to get on and off. Would be nice to have a easier and quicker way of taking end caps off or turning a ball valve open if that was possible to clean the lines out.
