The foam gun is quite nice but the $72 AM wants for it is nuts :nono
The local AM dealer I got mine from didn't even charge that.

Thanks Bill..I really enjoyed the thread about the foam gun..it is all very interesting..is there any way to incorporate a foam gun with a mobile detailing trailer..I have a pressure washer & a tank..but I am thinking that I would need something with less pressure, maybe a smaller different tank with some sort of pump & regular hose hook up..any inputs or info on this BillD (or anyone else)..thanks in advance.

I'd like to learn more about such a set up as well out of pure curiosity

Shallow-well pumps
These days, the most common pump for a shallow well is a jet pump. Jet pumps are mounted above the well, either in the home or in a well house, and draw the water up from the well through suction (see Single-Drop Jet-Pump System diagram on next page). Because suction is involved, atmospheric pressure is what's really doing the work. Think of the system as a long straw. As you suck on the straw, you create a vacuum in the straw above the water. Once the vacuum is there, the weight of the air, or atmospheric pressure, pushes the water up the straw. Consequently, the height that you can lift the water with a shallow-well jet pump relates to the weight of the air. While air pressure varies with elevation, it's common to limit the depth of a jet-pump-operated shallow well to about 25 ft.
Jet pumps create suction in a rather novel way. The pump is powered by an electric motor that drives an impeller, or centrifugal pump. The impeller moves water, called drive water, from the well through a narrow orifice, or jet, mounted in the housing in front of the impeller. This constriction at the jet causes the speed of the moving water to increase, much like the nozzle on a garden hose. As the water leaves the jet, a partial vacuum is created that sucks additional water from the well. Directly behind the jet is a Venturi tube that increases in diameter. Its function is to slow down the water and increase the pressure. The pumped water–new water that's drawn from the well by the suction at the jet–then combines with the drive water to discharge into the plumbing system at high pressure.
Because shallow-well jet pumps use water to draw water, they generally need to be primed–filled with water–before they'll work. To keep water in the pump and plumbing system from flowing back down into the well, a 1-way check valve is installed in the feed line to the pump.
So basically your shallow well is your water storage tank. I would advise putting in a check, because you don't want to prime the pump each time. I would also have a pressure switch on it so when your not using water the pump will shut off. I found a diagram, and as soon as I can figure out how to post it I will.

That first paragraph describes how my oil extractor works. That's another indispensible tool :bigups
