2 years ago, we upgraded the low-pressure setup and kept our ARO pumps. I designed new matching manifolds, fabricated in stainless steel, replaced the solenoids (KIP), added large 4" gauges, color-coded the poly-tubing to match the Magic Wand system. Blue = Foam Brush, Green = Wax, Pink = PreSoak, Yellow = Tire Cleaner, White = Air. I have 5 SS bays. In the pump room, the White Air lines are on the left and the chemicals are on the right. In the bays, we ran new HP hoses, zip-tied the poly tubing, wrapped with short pieces of rubber hosing and secured with pipe straps. I'm thrilled with the look! Now it's easier to identify any chemical leaks, in the future. Customers are impressed! My father tragically passed away when I was 18 years old, and I'm grateful that I inherited his analytical, organization & engineering skills. My dad would absolutely LOVE my car wash & all that it's become!!
