My well is drilled, my driller is reluctant to set a pump with poly because he is a die-hard PVC guy. I don't want to use PVC because of chemicals but also because it becomes brittle with time. So I am considering setting a pump myself using poly. Here's my plan, please comment as you wish:
Well depth is 400', static level 295 feet, 6" steel casing the full depth of the well, pump to be set at 380'. I plan to buy 300psi poly pipe and locate a backflow every 200' along the pipe (one in the middle, one at the pitless, one at the pump.) I plan to locate a wheel just above the top of the casing, perhaps a motorcycle wheel, so the pipe can be lowered from the horizontal over the wheel. A stainless cable will be attached to the pump. A heavy wood frame will be needed to hold the wheel.
I will lower the pump with my pickup. I'll attach the stainless cable to the truck hitch with a cam lock 75' away, and use a vise-grip type poly clamp (from Dean Bennett) as well, so I'll be gripping both the cable and the pipe. Back up the truck 75' toward the well head lowering the pipe, then secure the cable and the pipe at the head with a second cam lock and poly clamp, release the truck, drive it forward 75' again, roll out more pipe, wire and cable, reattach, release the locks at the head, lower again, etc.
So, myself and my helpers never lift or lower by hand the weight of the pump, pipe, wire and cable until it comes time to set the pitless. Just before the top end of the pipe goes over the wheel we attach a T handle to the pitless fitting, and continue lowering with the cable until the T handle rests (gently) on the casing. Then we have to lift by hand to set the pitless.
Sound feasible?
Got a source for cam locks?
Pump size is a different issue, for another thread. Thanks.
