I am pretty much set to start DS’ing with a 4gmp belt drive PW. I ordered a DS injector kit from PressureTek and have done a bunch of research. One thing which made downstreaming appealing to me is the ability to change tips in order to pull solution (with the wash tips) and then switch to a fan tip (higher pressure) in order to rinse.
I am seeing more and more that this does not work all the time and guys resort to walking back to the rig to switch to fresh water only.
If this does become an issue and I need fresh water rinse, is it a matter of pulling the draw tube from the solution tank so it does not pull from there or do i install a ball valve on the solution tank to prevent the PW from pulling water and solution? I will only have one 15 gallon solution tank for now.
