No, there are high-temp seals for most pumps, but those aren't meant for much above 160°. That boiler is probably 2/3 of your changeover time problem.

Your tip is most likely rated 4 GPM at 4000 PSI. That will be extremely low flow with only 90 PSI. You might want to test by hooking your gun to city pressure to get an idea of what the flow will be like. What you gain in changeover (if you gain anything at all) will probably be lost in the...

What kind of Flojet were you looking at? The little electric ones are not very high volume or pressure, so your changeover time with a 60 foot hose is still going to be pretty long. The G57 air operated Flojets can handle 7 GPM at 90 PSI, but you must be running a very small tip to run 3.9 GPM...

I just realized that using an injector at the boom will reduce your pressure all the time, not just while you're applying soap. You could add a solenoid on the main line to stop the flow and force the injector line to take over, but I'm not aware of any solenoid that will work reliably at 3000...

I doubt anyone even offers an internet service with a low enough bandwidth that it would be a problem.

I'll admit it does work even with it plumbed in reverse of its design, but the main reason the use the solenoid blocks is to cut down on assembly time and cost. There's no advantage otherwise, and there are several disadvantages. Kleen-Rite's setup is not at all space efficient, and could...

If you're going to run stainless, use 3/8" ID. You're only running 3.9 GPM, 3/8" is more than enough. 3/4" will make your changeover time worse. You could inject soap at the boom, but you generally lose about 20% of your pressure. It would be faster and simpler than a separate applicator...

I had someone threaten me with something similar. He was dumb enough to call the cops on me, ended up with a criminal trespass warrant. Watch for them to come, wait 'til they deposit their bill, then unplug the changer before it pays out. Tell them they'll get their refund after they've...

Need more info, such as how you plan to value them, whether you need secure ones, why you need tokens, etc. For example, I just mix them in with quarters so I can use the cheapest ones, and I don't need a lot. A friend/fellow operator needed custom ones worth $1, had to order 10,000 to get...

Why are the hard drives failing? Are they just ordinary off-the-shelf drives? Any idea if it's heat or if they're working themselves to death? You ought to be able to clone the data to a better quality drive, but you might have to have someone autopsy a dead one first.

I'd be more confident hearing from a cop if they would go after someone. You'd probably have to post a sign and possibly have a fine listed. They are supposed to be obligated to help enforce such a thing.

It uses an ordinary antenna for a wi-fi router. There are ones made for outdoors.

I'm seeing more and more places with signs up saying "Due to a national coin shortage we are asking you to please pay with exact change, card, etc." I put my last bag of tokens in the changer a few days ago which usually stops the changer abuse, but last night after just two days I'm about $500...

The Cryptopay readers will "daisy-chain" communication, so the issue isn't about how far a reader is from the coordinator as much as how far apart any units on the network are. I believe the maximum distance from one reader to the coordinator is 150 feet Brick doesn't seem to have much of an...

I'm pretty sure it was just the wiring. Sensortrons are probably the most waterproof of any acceptor.

I am every bit as qualified as anyone at that number, as I was factory trained in GP service and have rebuilt many hundreds of them.

I know for sure it was a problem with GinSan boxes. They'd spray soap in it which would short the coin pulse wire on the terminal strip to something next to it and then spin the dial or start and stop something with pushbuttons to rack up a bunch of time. They probably still run the wire off...

Windtrax if you're signed up for their free shipping. Kleen-Rite's prices are a little better but shipping from them is getting out of hand, and they'll most likely send you some of the parts and backorder the rest so you'll get double-dinged on freight. Windtrax (and most other suppliers)...

Here's the correct data sheet: http://www.general-pump.net/PDFs/T921-Pump.pdf It probably needs a seal kit. Be sure to inspect inside the manifold for washout where the seals sit. There's not a kit for just the seal parts, so you'll need a kit 148, half of a kit 11, and three 90.3616.00...

It looks like he's using a token. Notice that it's exactly ten pulses with each one. Regardless, it's fraud and I've reported it, hopefully it will get reported more and taken down.
