Equipment needed for installation
We include the all universal parts necessary for pump installation in your kit. But because everyone’s well and landscape are a little bit different, there are certain components that you’ll need to bring to the installation that we cannot practically provide. We do offer a ‘ Turnkey Kit’ in two sizes (100’ and 200’) on our website, which includes these additional items already assembled and packed together. This can be very convenient if you live a long way from a hardware store or are short on time. We love the DIY spirit of our customers and we’ll help you with whatever solution works best for you!
Here’s a list of the tools you’ll want to have on hand during installation:
Wire stripper/crimper
Screwdrivers (Flat and Phillips head)
Electrical tape (for attaching wire to drop pipe)
Teflon tape for tight thread connections (recommended)
Two adjustable wrenches
Heat gun or torch for heat-shrink sleeves
Multimeter (highly recommended)
Large bucket or barrel with water for testing the system (recommended)
Your pump will arrive with 6’ of cable attached. You’ll need to extend this according to your water level and installation design by splicing on a custom length of additional pump wire. To do this, use 3-strand submersible wire of at least 12 gauge. The distance between the pump and the controller will dictate the wire gauge required. In general, a larger wire diameter will ensure maximum performance:
For up to 200’ between the pump and controller, use 12-gauge, 3-strand wire
For distances greater than 200’, optional use of 10-gauge, 3-strand wire but 12-3 is most common.
The low water and tank full sensor each have 100′ of wire attached to the probe but you can use the included splice kit for extending your sensor wire if necessary with 16-22 gauge 2-strand wire (available in the Communications/ Home Security section of your local hardware store) following the same steps outline below. The two sensors in your kit are identical so either one can be used for the low water sensor.
Use the provided splice kit with adhesive-lined heat-shrink tubing to connect your pump cable extension. Your pump comes with butt crimps pre-attached for ease of connection; we also provide 3 larger diameter butt crimps in your kit for splicing 10 gauge wire if needed. If you don’t have a heat gun to shrink the tubing, you can use a butane lighter, but make sure not to melt the insulation or set it on re. You can also use a lighter, but be extremely careful not to overheat and melt the heat-shrinks.

Face panels due south for maximum performance, regardless of season and type of mount. During winter adjust for a steeper panel angle and a flatter summer angle. This increases efficiency the efficiency of panels which, in turn, allows you to achieve more pumping hours per day.
