So I had a well drilled a few months ago which ended up being roughly 165' deep and 6" steel casing with perfs. I am now ready to move forward with installing a submersible but I am having a hard time paying a well company so much money for something that doesn't seem too hard, in my opinion, so I am wanting to do this all myself. The well has not been sounded so I am planning on trying the coke bottle trick to get the depths myself. After this I would like to install a Grundfos pump down into the well but have a few questions first.
- .5 vs .75 HP pump? I have heard .75 would be better for direct line to house and .5 would be better with a cistern.
- SQ vs SQE? I believe the difference is just that the SQE is constant pressure, correct? Do I need this? I am planning on NOT having a cistern, pending GPM test is around 8-10. This should put me at about a 90 gallon pressure tank in the house.
- Do I need a 3" or 4" pump if my well casing is 6"?
- Traditional pipe vs Poly pipe? I have been wanting to use poly just because it looks much easier for a two person install without cranes, etc.
- I am assuming that a torque arrestor is still needed even with poly?
- Check valves. How many and at which locations for 155' set depth?
