Neither one matches what he asked for. I took a leap and guessed he might have DEMA proportioners or someone used DEMA parts on a Hydrominder. DEMA is the only one I've ever seen with a threaded tip in a 1/4" barb...

There's an operator here with two sites in which he has CC and bill acceptors in the bays, only tokens from his changer. He has a bill breaker changer that gives either a token for a $1 bill or three tokens and bills for change for a $5, $10, or $20. He does not take bills in his vacs. I'm...

He said the tips thread in.

It matches your description. Hydrominder eductor tips that small doesn't have threaded tips.

I used to run a site with a Vector. I just put up a sign that said not to use the top wash when it's below freezing. I tried manually blowing out the lines as an experiment, but it took way too long for them to fill. That also makes an antifreeze purge not an option.

It's either the solenoid for the bay or the controller that turns on the pump for delivery. Everything you're checking is for the production of the water, not the delivery. Your complete lack of understanding of how this system works tells me it's dangerous for you to be servicing it. You...

If the pump has cast iron parts, put a cleanable strainer on the outlet. Replace everything else after it with brass barb fittings and hose rated for 250-300 PSI.

Yup, the tool is very easy to use, requires no skill, and once it's set you lock it and you can make key copies off it.

I didn't know they could sink them vertically. That certainly makes a difference.

Sounds like fun.

I was referring to using the geothermal heat that's naturally just under the ground as free, passive heat like they do in Iceland. The geothermal we use in the US isn't the same, it's just digging down far enough where the earth is a relatively constant temperature, 50-60° F, which is used to...

Mechanical Laurel vendors cannot take a dollar coin. I replaced the coin mechs in mine for ones that take both quarters and .984 tokens since I mix those tokens into the changer, and that actually works fine. He'd have to take ONLY .984 tokens, everything would have to be a dollar increment...

I've seen foam heads made from PVC electrical conduit sweeps with very carefully spaced holes drilled in them.

It has several big ones. You have to move to an area where the Earth's crust is thin enough to tap into it. You can't generate electricity with it. There's enough usable area to heat 17% of all people's homes.

I hate to tell you, you're going to have trouble with it in a couple years. It may look simple but it has all the same solenoids as most other washes, everything has to be adjusted perfectly for it to work at all, some of the solenoids are high failure, difficult to access, very expensive, and...

IMO you will have to replace the mechanical Laurel vendors, or you could stop selling vending. I went my first six months without vendors and sometimes wish I still didn't have any, but I can use that extra $3,000 a year. FWIW I'd love to have a glass-front vendor with snacks and drinks and 20...

Cavitation is mainly caused by a restriction of the water supply, not by air entering the system. The parts damaged by cavitation are fully exposed to water and aren't involved in mating to a seal. The seating surfaces would have to be completely and very obviously compromised before the parts...

Google Voice. It's free, you can have the calls forwarded to a cell phone and have it display either the caller's number or your Google Voice number, you can receive both texts and voicemails via your email, you can add the app to your phone and call people back from the number so you won't...

It's simple math. Read the manual.
