    R.O problem with high membrane flow

    If you still have the old membrane, put it back in the bag the new one came in and seal it the best you can. It will keep for a year or two and still work.

    Foam brush problems

    I mentioned that in an earlier post, also how I had just put on a new hose which worked fine when I tested it, but after that the water would jet right through the ring without touching it and it wouldn't draw at all. It might be worth another look.

    Has anyone ever regretted Cryptopay

    I had to do it accurately by watching surveillance video and counting the cars washed, subtracting the CC startups, and dividing cash spent by the remaining number.

    CarWash Consignment

    That's interesting. Maybe they've read the complaints here. It used to be that you'd never get a reply, and one person said they took more money for an item than the seller had it listed for.

    DILLING-HARRIS - Spot free rinse

    It doesn't use salt, just turn it on and it should do what it's supposed to.

    Display board

    There's a contrast control on it that might have gotten turned all the way up.

    R.O problem with high membrane flow

    It's possible the pressure is too high, or something with excessive pressure is feeding back from somewhere and destroying the membrane. They can't handle ANY pressure in a reverse flow.

    Sounds like bait-and-switch.

    Threats on the horizon: any opinions?

    There are tunnels where the customer drives through slowly with lights to help time their movement. But as a rule, a "tunnel" is where the car moves through stationary equipment. Other than the dryer, an IBA has the car stationary while the machine moves around it.

    Hydrominder Inlet Screen

    If your water pressure is too low to flow through a 5 micron 2 x 10" whole house filter, it's too low for a Hydrominder to work properly. And now your point has changed from gravity feed to city pressure...

    Foam brush problems

    Put a zip tie really tight on the hose around the foot (to act as a clamp) valve that goes in the concentrate to prevent the liquid from draining out. Also make sure there's a hole in the discharge tube on the Hydrominder outlet, above the mixed liquid. You might have a siphon issue that's...

    Hydrominder Inlet Screen

    We weren't talking about gravity feed lines, we were discussing supply to Hydrominders.

    When/how often to change vac bags

    I've seen mismatched motors many times, doesn't seem to cause an issue but the vac is a lot noisier.

    DILLING-HARRIS - Spot free rinse

    The pumps they use need to be primed. Try that first, make sure the tank is as full as possible, disconnect the outlet and let the water flow until there's no more air, then turn the pump on for a couple seconds at a time until it's flowing as strong as it will get, might take three or four...

    Help me break in!!

    This might work. Could also try the 5-minute cure JB Weld putty, rolling up a small ball of it, sticking it on the end of the T-handle, pushing that into the nut and waiting five minutes for it to cure, then try pulling and turning. The quick cure JB Weld isn't very strong and it shouldn't be...

    I've never heard that expression before.

    RO Help

    I was going to suggest that next. If you're not happy with 4 ppm and you didn't clean and lubricate the o-rings that seal against the tubes on the ends of the membranes, that should improve the seal.

    Hydrominder Inlet Screen

    The smaller the better, 5 micron should be more than fine enough and will last longer than a 1. I get a lot of really fine silt in the holding tank for the high pressure pumps, so I'd probably use a 1.

    Buying second car wash near my first

    Seems like for 21k you can't go wrong.
