Just got my XJET M5 and threw on a proportioner and the hose. I see now that it makes more sense to have the beige proportioner pulling straight SH with my 4 GPM machine for about a 1.25% mix.
The issue is I need to have a hotter mix for concrete work. If I have a job that requires me to clean vinyl AND concrete, which is the easiest way to switch between batches? Should I switch between each proportioner? Should I carry around two different pails each with their own mix? Granted, I am having a nearly impossible time taking the hose off of this damn thing.
I know this comes across as snarky, but the sooner you can fabricate a dedicated 12v system the better. Like you I got fed up with the X5 so built a 2gpm 12v using one of those ammo boxes and had good results with that for a year until I built a trailer mounted unit.
It’s really simple to make, just a 7ah battery, waterproof switch, 2gpm pump, Flexzilla hose and spray gun with appropriate nozzles.
Throw the proportioners away. If you’re just using a five gallon pail it’s easier to mix the pail for your needs. Also, throw the xjet away. DS’ing is much more effective and effecient. Also, if you buy a 12v system, throw it away. It’s only purpose is roofs and they suck anyway.
If one side is really dirty you could always hit that side first before diluting your SH with water, then dilute and wash the other three. But I think you’ll be fine. And you just need to find a routine that works for you.
Some guys swear by them for washing vinyl. Most don’t. But if that’s what you need to do, then go for it. Nothing wrong with using one. It’s just that most guys believe you can go quicker without dragging a pail around and two hoses. And I agree.
We wash with it…when the DS injector craps out, no one thought to replace the spare in the truck last time they changed it out, and the softwash gun gets inadvertently stepped on (and again, no one replaced the spare), and it’s an hour from the shop…in that case, it’s perfect! The crew really had no clue what % was hitting the wall, but it was somewhere in the range of usable…rinse when it’s done, or apply again if it was too weak, problem solved.
