	The Franklin AIM manual (http://www.franklin-electric.com/media/documents/M1311_60_Hz_AIM_Catalog.pdf) is the go to source for information on submersible motors. Single phase wire sizing is on page 11, for a 230v 1/2HP pump you can have up to 400' of AWG 14 wire, or up to 650' of AWG 12 wire. In actual practice, we generally don't use wire smaller than AWG 12, but it would work.

			'''Regarding Pump Vibration and Fittings'''
	The pump shouldn't really vibrate if things are working correctly. There may be a slight "humming" sound from the pipes but no major vibrations. Generally we don't see any issues with pipe fittings coming apart. The pump will jerk downhole from the toque when it turns on and can also have a jerk when it shuts down. The pump startup jerk is can cause issues with the wires rubbing against the well casing and eventually rubbing the wiring insulation off, so tape the wires to the drop pipe in several places.

The pump startup jerk is can cause issues with the wires rubbing against the well casing and eventually rubbing the wiring insulation off, so tape the wires to the drop pipe in several places.

	When splicing the pump wire to the pump, use the submersible pump wire splice kits, I think Menards has them. They use a special heat shrink tubing that has sealant built into it to make a waterproof splice.
	If it was us, we would use 1" 160psi poly pipe to hang the pump in the well. The pump will most likely have a 1 1/4" female pipe thread, and I'm guessing you have a 1" slide pitless, but you could have a 1 1/4".

	Don't forget you will need a 5 or 6' long steel pipe to screw into the top of the pitless to use as a handle when you set the pump, then you remove the "handle pipe" before you put the cap on the top of the well.

			'''Regarding Electrical'''

			use a "submersible pump splice kit". I think menards in St
			Joseph has them in stock, or if you're not in a hurry, I could mail some
			to you. They use an in-line crimp connector, and then have a special
			heat shrink tubing that goes over the splice. The heat shrink tubing has
			an adhesive sealant that seals up when heated, the tubing also usually
			has a shrink ratio of 3:1 instead of just 2:1.

			We actually crimp, then solder the crimp connector on all the submerged
			splices we make, then put the heat shrink on them. Most people don't
			solder like we do, we just like to eliminate as many failure points as
			we can.
