shower feed system

It seems like we all like to build things here that could otherwise be bought somewhere else at a premium.  I want to hook my scrubber and crb up to my mytee big boss sprayer so it feeds encap or prespray while I'm scrubbing.  This would effectively allow me to remove my chem tank from the scrubber and add a chem feed to both machines.  Excellent supply makes an add on for both machines, but $329 seems expensive for a push button control valve, check valve and plastic tubing.  JMO but I could probably do it in half hour with $100 budget.  Attaching picture of excellent supplys product for visual

Sounds like a great idea...those set-ups really make things more productive.

I had the same thought. I was thinking about just adding a soft touch valve connected to a row of jets attached to the front of the crb. That way you just hook up a 100 psi pump attached to a 5 gallon bucket and you just have a solution line following you around. Or better still an injection system hooked up to a faucet.

Mytee had a reconditioned section on their website, can grab amytee big boss sprayer for 385. Add 50ft hose, trigger on handle, 110 degree 2 flow jet on front

I agree field fabricated spray systems work quite well.  I've dabbled with the pepsi tank and a feed line to a Gun trigger on my CRB, I found the line got in the way so I mounted the tank within the handle cavity, the 5 gal was way to heavy and I intended to acquire a 3 gal pepsi tank and try again, haven't yet. Pumps are inexpensive and the 5 gal bucket set up is viable. When this topic came up at the old hangout a while back someone had mentioned just connecting to a porty for the tank and then spray with heat. The soft touch mounted on the handle was also a good idea, can't recall who did that. Mo didn't you modify your machine with sprayer?

Wand valve is what I would do too ... If I were to do that.
It would still be faster, to just in line spray from the tm, turn off machine, then bring in crb.
