I had my well drilled yesterday. An earlier thread really helped me figure out my needs/etc and how many things I needed to figure out. My well is 475' deep and static water level is 375'. Well refresh rate is over 10gpm. I am going to install my pump myself and plan to set pump at 425'. Any thoughts or critism would be very appreciated. Proposed components:
- 250PSI SIDR 1" poly tubing - 4710 material and meets ASTMD2239 SIDR 7 - I found 500' roll, so no connections except at pump and pitless
- Grundfos 5 SQ-15-450 pump - 1 1/2 horse and soft start
- Extra long SS barb connectors with (3) T-bolt clamps at each connection
- Pitless adaptor
- 2 wire 12 awg well wire
- 3/16 SS wire safety cable - this may help with pulling and placing pump - I have lots of experience with wire rope and rigging
Questions:
- Should I add a check valve above the pump (pump comes with check valve already)?
- Does anyone ever connect the safety cable to the tubing with SS hose clamps (say every 25' or so) to help with stretching, etc? This would also eliminate risk of safety cable breaking and falling to the bottom and making it hard to get pump out. Not sure if the hose clamps would weaken the pipe if it were to stretch though and cut into drop pipe.
- Since my pump is soft start, I wasn't planning on using a torque arrestor near the bottom - thoughts?
I know the poly will stretch and I will leave some slack with wire (although will tape every 7 ish feet). I will use my tractor to help with install and will buy or build something to keep pipe from kinking against casing. I installed a pump at 200' feet on old ag well about 7 years ago and it has worked fine since, so I have some experience with this process.
Initially I plan to just pipe pitless to frost-free hydrant at first, but will add 40+ gallon 40-60 pressure tank at some point. If my pump can't supply enough water with pressure tank attached, I will pump to tank at surface and then pump from there.
I will have help on install and have figured out my total weight will be about 230lbs. I am confident I can handle that with rigging/tractor/extra helpers.
If I need to remove pipe/pump, my total weight will be around 375lbs and with tractor should be able to deal with that as well.
Thanks for any help!!!
