We have a 1 1/2 horse well pump we installed on 180 ft of 1 1/4 black Poly pipe. We only had 100 ft rolls so we put a barb coupling double clamped. After a day of running the pump, our coupling pulled apart. After a hour of pulling we finally got the pump out. My question is with a horse and a half pump that deep, are we still fine using poly? And was our error just that we didn't put in a continuous run? We have put couplings in like that on other wells but always on 3/4 pumps with 1" poly. Any advice would be great.
1 1/2 horse well pump pipe?

Some extra long barb x barb couplings have 12 barbs on each half. http://www.deanbennett.com/insert-brass-fittings.htm Some people put 3 ideal stainless clamps on each side. http://idealtridon.com/aftermarket/12-hy-gear/
You might torque the clamps, wait for a time (I don't know how long) and torque again. 35 inch pounds is just under 3 ft pounds.
The worm gear should be on opposite sides of the pipe for adjacent clamps.

Long barb fittings are the way to go. But it depends on which 1.5HP pump you have. A 10 GPM series can build 282 PSI against a closed valve while a 20 GPM series can only build 138 PSI.

Was it a brass insert coupling? I wouldn't expect that to come apart. I could see a nylon or pvc one failing like that.
I tighten the clamps lightly when the pipe is still warm then torque them after it's cooled.
I pretty much never junction poly, I prefer everything be continuous. On 1HP and larger pumps I always use the longer hose barbs so everything can be triple clamped. No one around me carries an extra long insert coupling(if they even exist) so if I needed to I'd use 2 extra long adapters and a coupling.

Poly pipe sucks for downhole pump installs, especially with a 1.5 hp pump, but it's cheap, goes in the hole fast and you don't need a hoist truck.
Sch 80 pvc is the preferred material to use.

I find installing on PVC to be way faster.
Poly requires more wire protection and taping.
I'm not convinced one is really better than the other. I have plenty of wells I can't get a pump hoist near. On those we use poly.

Do you tape the wire to the inside of any curl/set?

Pretty much yes. It's an active effort to straighten it and match the wire to length. Too loose the slack will hit the sides, too tight and it will break the wires on the taught bows.
PVC is easier don't have to deal with that crap, everythings already straight.
