Carwashguy, that is why I included the link to the wash package menu.

Because I offer 2 step-presoak, spot free, drying agent and dryers, I'm pretty sure I'm breaking even on the $5 wash. Here is the seperation: $5- mentioned above $7- adds undercarriage and rocker panels $9 adds triple foam and 2nd HP rinse $10 adds it all plus rain-X. Pretty significant...

All the posts I could find on this topic are more than 7 years old, so I thought I would start a new one. First Question: We currently offer $5, $7, $9 and $10 wash packages. It has been suggested to me by our chemical supplier to only go with 3 options in stead of 4. His contention is that...

How do you find/view these photos that have been made into a "sticky?" Thanks, Brian

What is a "sticky" thread? I can't find the posts with the pictures/descriptions of the 310 manifolds. Thanks, Brian

Update Just to finish off this topic, I went ahead and installed a flojet. It was pretty easy and not too expensive, so thanks for the suggestion! Under further investigation, the issue was not with check valves or anything else. It was the pressure tank. The tank was totally full of tire...

Yes it does have a pressure adjusting bypassing valve. The paperwork says its factory set and not to adjust it...

Went ahead and added TWO brand new check valves. One between the pump and the pressure switch. Another just below the solenoids. As suspected, no change. The pressure drops from 60 to 40 over and over again. So this leads me back to the expansion tank. OR, could a small dripping leak cause the...

The only check valve that has ever been there is the one after the pressure switch/expansion tank and right before the solenoids. Is it possible that procon pumps don't allow liquid to flow the opposite direction and fluid-o-tech pumps do? Sounds like a check valve right after the pump and...

How do I combine the 2 threads. Not sure how it was posted twice.

No it's just before the solenoids and has been that way for years.

I can appreciate your approach. This current system has worked great for a decade, plus. I hope it's not necessary to purchase a controller and re-wire this as the solenoids hang high on the wall and the pump unit is on the floor. Seems like unnecessary work and expense if simply replacing the...

Actually, as stated, I eliminated the check valve and plugged the outgoing hose. I actually plugged it by reversing the direction of the check valve and leaving the opposite end open. Not only did no liquid come through the valve, showing that it is functioning properly, the system continued to...

Procon Pump Expansion Tank Tire & Wheel Low Pressure Delivery Issue Our tire & wheel cleaner is distributed with a pressure switch, electric motor, procon pump and expansion tank. We also have needle valves to adjust the air. Issue: The procon pump would not build enough pressure to turn the...

Our tire & wheel cleaner is distributed with a pressure switch, electric motor, procon pump and expansion tank. We also have needle valves to adjust the air. Issue: The procon pump would not build enough pressure to turn the pressure switch off. Solution: Replaced the procon pump. Was talked...

AC. What is leakage voltage and what could be possible causes?

We added a grundfos pump and increased some copper pipe from 1 inch to 1 1/2 inch to get more water and to help our new Navien heaters to function better. There were several ground wires connecting different pipes and I'm not sure they got them all back in the correct spots. Even the electrical...

The boxes are not daisy chained. Each bay is wired directly to the site controller. Thanks for the troubleshooting sequence. The washcard tech's have been pleasant to work with, but sure didn't have these suggestions. The acceptors are all working right now, but I feel like it is only a matter...

Do you think it's likely that these 4 volts are what's causing the card not to process in the one self-serve box and in the automatic payhead? There are also 4 volts in the other 2 self serve bays and those process cards nicely...

I don't think "floating" voltage was the word I should have used. We use a 24V AC and a neutral. (as far as I know!)
