Another reason not to bump an old thread is now you've got even more people replying and not noticing that it was over a year ago and the issue is 100% certain to have been solved already.

For the cost of a set of new bushings for a 7-bay Coleman SS I can buy a small machinist lathe and make new ones out of UHMW-PP that will last almost forever. Thoughts?

You don't need a remote to change the time. There should be two buttons on the back of the timer to set the time and price. I don't know if you can change the settings with the remote, but if you can it should be the same as using the buttons. What model timers do you have? I don't have a...

I have considered branching out into the Florida area but I'm getting too old to keep doing this all day every day. My fiancée has family in Florida and it might be possible to travel back and forth every few weeks.

If you get through and someone tells you that you need to talk to Jim, don't bother leaving a message because he probably won't get back to you. Tell them you'll hold until he's available. Then be ready for him to talk your ear off.

Totally unnecessary if you use a good quality salt.

Where does that say he thought it would stop the leak?

No one suggested that it would.

This is not a DIY forum. There are plenty of those out there.

The only time I could see an injector pump working would be if you have one pump per bay and it's foam brush. Any other function will vary in flow whether the trigger is pulled or released, and you'll need an injector pump for every bay unless you have one that has multiple speeds.

I didn't use one because I felt like the restriction might affect the dilution, but I wasn't using any recommended tip sizes anyway so it probably doesn't matter, plus the screen in the foot valve would trap particles that might plug the tip. I haven't ever had an issue either way, but I...

You can replumb any RO system to recirculate a portion of the reject back to the pump. A flow gauge is handy but NOT necessary. Totally unnecessary for car washing.

This does work.

Yeah, 'cause if you don't...

Same, I hold my hand about chest level and the claw nozzle should instantly stick to my hand and hold the hose off the ground.

The injectors themselves?

There could be an issue with the pump like bad seals, your belt could be slipping, the tip in the bay washed out, or a defective check valve. A car wash pump isn't usually set up to reach over 1500 PSI because you really don't want more pressure than that or you risk a customer injuring...

There are several possibilities. You may not be making enough flow to reach 1700 PSI with the trigger pulled, but when it's released the flow drops and the pressure comes up. When you set the pressure, watch the gauge and if the needle stops increasing as you crank down, back it off until you...

The older mechanical vendors max out at 4 quarters, then they came out with the ones that do up to $3, and they're pretty finicky. Yes, a 5-column air freshener vendor would be a good idea along with some 3-column.

I know one operator who has done both a dog wash bay and ice/water machines. He says he makes more from each of those than he does from each bay, but his SS is seriously underperforming.
