HIDIM: Installing a Nemo 24 volt DC solar well pump

Here's how I installed my Nemo 24 volt DC solar well pump. 

Update: My second Nemo pump died. What Went Wrong? https://youtu.be/U_5ErRVEIE0

Don't forget to disinfect it afterwards!


I don't show you how to crimp things because that's not a skill specific to this project and I am not particularly good at it. Learn from someone else! 



Apologies that it got dark, sometimes that happens around here.


I don't have a head cam so for now everything is just filmed on my phone.



Terms I may have abused:

- Static water level: How far the surface of the water is from the surface of the ground. 30' in my well.
- Pump depth under water: How far below the water surface the pump is. 40' is max specified by Nemo.
- Casing height above ground: How high the big white well pipe is above the ground. 2' for my well.
- Pitless adapter depth: How far below the ground the pitless adapter is - which should be below your region's frost line. 2'2" for my well.
- Max head pressure: The pressure exerted by the water in the pipe above the pump, assuming the well's water level has been drawn down. Roughly equal to the pump depth below the ground / 2.31. 70'/2.31 = 30 PSI  in my well. Sometimes this is expressed in feet.
- Max system pressure: The max head pressure + the max pressure as dictated by the pressure switch on the pump control: 30 + 60 = 90 PSI in my system.

00:0 Introduction, what you'll receive
0:51 Buy a fitting that works for your pipe and install it with some suitable sealant
2:16 Determine pump depth and pipe length
2:44 About my poly pipe, how much I'm using
3:44 Cut the pipe (and in my case, wire)
4:39 After the cut, what's going where
5:36 Prepare to connect the pipe to the pump
6:35 Review of the pipe connection
7:00 Prepare for wire splicing
8:24 Make some bad crimps and seal it up
9:03 Electrical tape is gonna give me cancer
10:08 The Blair Witch was a good movie
11:06 Torque arrestor (optional) installed
11:48 Pump-end is ready to go in, now get the top end ready. Understand the pitless adapter, pump removal tool.
12:48 Pipe installed onto pitless adapter, more electrical tape!
13:18 Get familiar with the well
14:18 Place your prepared pump into the well and lower it down!
14:50 Pipe is in the well, prepare to seat pitless adapter
15:46 Pitless adapter is seated, now pay the piper on your short wire.
16:56 Everything seated, connected, and ready to test
18:02 First test and self-priming of pump
18:40 Test from pressure tank after building 60+ PSI
