one free "chosen" wand to the best post of the month. JK

agree on all points. Just as a sidenote there was a Facebook question posted. guy had a HDM TM that had problems with their chem pump so he asked what the chem dilution would be if he put the chems in his water supply tank. (you know, rather than asking how to fix it) I replied that this would be a bad idea and explained why. Then others were saying I was wrong and what to put in the tanks. you cant fix stupid.
For over 30 years I mixed my rinses in my fresh water tank with softened water. I knew the EXACT dilution of my chemicals in my rinse solution. The only adjustments I ever made were in the dilutions of my prespray, stronger or lighter as needed. Chemical injectors and pumps are a guessing game as to dilutions. More than once I came out to the truck after a job and either a inch of solution was drawn out of my chem feed jug or the entire jug was gone. As far as damage to components I never had any ill effects or shortened life on transfer pumps, pressure pumps or lines. My internals were clean as a whistle any time I took them apart with good chems and soft water.
Not arguing with you as to what is better. It just worked well for me.

This confused me?? I dont see the problem with premixing chemicals then pumping unless they flammable or damaging to diaphragms and/or sealssuch as Petroleum basded products . After all thats what you do when you run a portable machine. You premix your solution and then pump it. Also it your tm uses starvation instead of a chem pump your system has chemicals running thru it also because the suction of the pressure pump draws the concentrate, Whats the difference? I personally wouldn't do it but i really dont see a problem

These things all depend on the design of the machine.

Some units have components that aren't friendly to acid rinses on one side, or alkaline detergents on the other side.

The "big name" slide ins use a controlled bleed system that bypasses a trickle of hot water through a small orifice and screen that is easily clogged by undissolved chemicals or built up detergent residues of even well dissolved liquids. These and a few other units also bypass water back to a water box which can causes "ready to use" amounts to increase concentration as they return to the water box.

So, the answer really is:

It depends on the machine you are running, and it depends on the stuff you intend to run through it.
