Personally, I would isolate the pickup.
Then you need;
* an open position on your rotary dial
* a decal for "spot free"
* a pump (I use a Cat 310) and motor
* a pressure regulator (I run mine between 250 to 300 psi.)
* a relay bank or multiplexer to engage the motor
(here's a thread that may help choose between the two, I've used relays that have been in service for over 25 years)
* single hose running from pump to a solenoid panel
* solenoid panel
* hoses running from solenoid panel to each bay
* checks at each bay manifold
* signal wire from bay box to solenoid panel and relay bank or multiplexer
* checks out at the bay
- I think that's everything ...

THanks for that, meter box wiring and place on the dial is in place.Personally, I would isolate the pickup.

I dont have room todo a standard pump stand setup. My iba has a pump just anchored to the wall, was thinking something along those lines and wondering what specs or if i even need something that big.

You know what, you could make a plywood or sheet metal panel 18" X 18" with a 1/4 or 1/2 hp motor, a Procon pump with a regulator and get everything else on it. Here's a pic of my old presoak system doing essentially the same thing. The only thing missing in the pic is the relays. The 120V electrical outlet is controlled by the relays. Run a screen before the Procon as well. I'm sure you'll get some better ideas than mine on here but it's definitely doable and fairly easy.

I'd get a 240GPH procon pump capable of 250 psi. You could also opt to use a booster pump with similar specs. You also need a regulator, a couple of relays (or a multiplexer), and a line to recirculate from the regulator back in the tank. Use 3/8" nylon (high pressure)line to the bays, and use individual 3/8" solenoids( not a 1/4" manifold).

What size line from the pickup and what kind of line? Also for for the recirc cant you just recirc it back into the supply line like a cat pump does?

Yes, that makes it more complicated, as the vast majority of pumps are not suitable for lifting from an underground tank. What type of spot-free pump does your auto use?

We have an underground tank and use a Cat 1010 for our self-serve spot-free delivery. It is not a cheap setup, but it delivers 400 psi to the bays, which is really noticeable compared to other washes. Instead of that, you can get a smaller above-ground tank that has an automatically controlled transfer pump from the underground tank. Then, you can use any other pump that can be gravity-fed (flooded).
