I've wanted to experiment with a Dosatron or DEMA Mix-Rite pump to inject soap and wax into city pressure water feed to the pump, but I haven't wanted to spend some $300 on a pump just to try it.All of our washes are pressure fed with the exception of one. I actually prefer the gravity feed set up as it is the most trouble free. Our psi fed setups use a Generant regulator followed by a large injector to which the soap and wax solenoids are attached. By adjusting the regulator psi you can greatly change the flow of wax and soap as seen on our flow meters. I'm not sure why but the regulators always seem to need adjustment to maintain the correct soap/wax flow. I've mulled around switching some of these setups to gravity feed but it would actually be a lot of work. Has anyone had success with eliminating the regulator and somehow psi feeding the wax/soap? I'm looking for the least complicated way to keep the system pressure fed while eliminating the most troublesome component (regulator). Thanks
Randy how are you setting your regulators? Do you set them to a specific psi. If you could, can you post a pic of your injector set up? If its easier, PM me and I'll give you my cell phone # to text pics to.We must be live’n right. We’ve had very few problems with the city water fed system or the Generant regulators over the years. We never have to readjust them, pretty much just set them up and forget them. We have had to replace the orifices in the DEMA 203 injectors once, they had gotten pretty worn. We’ve converted a few gravity fed systems over to pressure fed with excellent results.
I don't have the same experience with the hot float tank cooling down. When I made my new hot water float tank, (It holds about 10 gallons) I designed a heat exchanger, purchased a t-stat, and SS circulator...One of the experienced members on the forum (Cantbreak80) told me I was wasting $$$ and energy with trying to implement this idea...I'm glad I listened to him! All I did was wrap the hot water float tank with aluminum foil faced bubble wrap insulation that they sell at Lowes or HD....Even after 12-16 hours of no use, the tank lid is still warm to the touch. When its cold out, the HP hose feels warm even on the first use of the day...IMHO, you can scratch all those components as they are not necessary.Also, the hot water tank cools off in between uses, so throw in a tank heater element, which requires another 15-20 amp breaker and is inefficiently keeping the water hot, or put in a small recirculation pump to reheat the water in the tank when it cools. another 15-20 amp breaker, pump, and extra plumbing.
Yes it was.MEP is that for me
