Hello, so I bought a van with the steamway mastermatic galaxy 4100

And the previous owner had the chemical injection taken out and he was just using pre spray forever.

I want to get it hooked back up so I picked up everything to repair and bring this machine back to its full potential, but this is my first truck mount and now I read that injecting before the pump is bad..

Is it possible to install the injection on the pressure side instead?

Do the chemicals actually do bad harm to the CAT 310 pump?

I attached the diagram on how it comes from factory

Any input and help would be varyich appreciated.

Don't worry too much about injection, keep the pH between 5.5 & 9 and go to work. I purposely only treat my freshwater tank with a slightly acid rinse to lubricate my entire pumping system. Catpumps are a car wash favorite and regularly live 15+ years with mild chems going through them the entire time.

Question about steamway 4100. I bought a setup from a crook in canton Ohio and it has a bad heater coil, and a bad wastewater tank. Water either doesn’t make it to the tank or the tank has a hole in it. Can these tanks be repaired, and is this machine worth repairing? I’ve been duped.
