If the pipe breaks near the pump and the pump is hanging slightly sideways, how much of a problem will it be to get it out of a damaged or narrow well?
You are building a first class rig and I am really impressed with the quality of your work. Is it really worth it to you to use a marginal pipe? You have been advised by people that know way more than I do to get the 200 PSI pipe. They even suggested the 160 PSI pipe but they seemed uncomfortable with that recommendation.
I'm on the fence with the tube still. I have to go poly due to ID, the pex is just to restrictive. To be 100% honest, I jumped the gun on the tube and spent all my project fund so far. It was supposed to come in under $600 and I'm a little over now. I may have to wait a week to to recoup a little and go for the higher rated poly tube.
This is exactly why I am posting the project, to get feedback. Plus, it may help someone else spring an idea. It makes the gears turn. If it wasn't for money LOL!!
I found some 10/3 yellow cord!!
