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.
Use the same tip you soap with. Either pull the tube, get a three way valve one going to chems the other going to water tank this will help clean your injector out too when your done or get a remote downstream valve, my preference. I wouldn’t use high pressure tips to shut off soap though.
I’m on board with the 3 way ball valve. Swapping to high pressure tips is asking for damaged siding imo. A remote box is in my near future. I’m just not that fancy yet lol.
Guys don’t walk back to the truck because it doesn’t work it’s because they want to continue to use the low pressure tip they use for soap, to rinse. Most have 8 gpm machines and find the rinse tips to strong. This will be not be that significant with a 4gpm.
I keep a shut off ball valve just b4 my gun. Turn it about halfway to put some pressure in the line and it shuts soap off. Wide open and soaps on. Doesn’t affect pressure at the tips but might give slightly less flow when rinsing.
The schertz box does look appealing tho I will probably get one at some point this year
Ehhh I can’t see any harm that could be done. You can’t turn the valve too far obviously but just enough to here the pressure forming will shut the soap off. I’ve been doing this since the beginning of last year it works good
Explain to me how making pressure with a pressure washer is bad lol same principle as using a higher pressure nozzle to stop soap but I can still use my softwash nozzles and Im not running back to the truck every time I need to switch to rinse . I will say my machine works a little harder because of the pressure tho so the schertz box would be nice
