It is either drawing in air or there is something stuck in one of the check valves.

Yes, agreed. I don't mean to hijack Lisa's thread (as I hijack Lisa's thread) but this forum and the posters on it have saved me so much money, time, energy, sanity, and many years of my life. There have been many times when I have been helped immensely just by reading old posts and not even...

Change your mid limit switch.

I also disagree with making your vacs free. That only guarantees zero income from them every week.

Excellent. It's always good to solve a problem, especially if it's an easy, free fix.

Do you have an emergency shut off switch, possibly for low water to the pump(s), that shuts off power to all the bays? That could be acting up or have loose wiring.

Is the undercarriage/rocker panel spray important to the cleaning process (I believe it is)? If you do away with the $5, then every customer going through your wash gets that important feature. Some cars won't need it, but right now you are leaving that choice up to the customer and you run the...

In my opinion it is better to have 3 wash choices because it is difficult to make a real separation of services offered between each of the 4 washes. I would say you should drop your bottom wash altogether. Since you are making new signs you should consider raising your prices to maybe $12, $10...

255k gallons in a year could be one car and a leaky sink.

The mid limit flag is the point at which the Lasermind switches its attention from the rear limit switch to the front limit switch, when the bridge is moving forward up the passenger side. If the front limit switch is giving a false positive before the bridge is at the front limit flag, then the...

If you ignore the grease coincidence, it sounds like your front limit switch/cord is bad, like washnvac said. Is the bridge stopping when it passes the mid-limit flag?

Is that the same grating they have sold for many years? I have some in use in my bays. Aside from the dirt, they look the same now as they did when they were new. They get driven over many times a day and I've had them in service for at least 7 years.

That works for witches too, right?

As I have responded on another thread, you have an intermittent x30 issue. Maybe it's related to the x30 wire issue you mentioned on a different thread. I would try to get that figured out as well. As far as scratch resistant covers go, was it the cover that scratched the vehicles, or the...

Sounds like the trolley is intermittently travelling too far to the right when it is at the rear of the vehicle. This would not be an arch rotate problem, but more likely a measurement problem. The arch rotate failure is just the result. I would start with the x30 prox switch. Is it scuffed up...
