For my submersible, all I had to provide was the 220 power line to the control box. The wire that went down with the well pump was furnished by the installer.
Not sure how to translate the message from your wife, but twilson may have it right on. If me, I'd contact the installer directly and learn first hand what is needed.
Frustrating when an installer (I am dealing with a shower installer now and getting information needed to prepare the rough work for them is like pulling hens teeth) doesn't communicate what is going to be needed on site, until they are ready to show up. After ordering the shower base, and the plumbers are there to do the rough-in plumbing, they are asking me what size the drain hole will be. I ask "Isn't that standard with shower bases?" and I get a 'dumb' look like "How should we know?", as if they don't install them and hook them up several times a week in new homes. Duh?
The shower base came, at about 250 #'s, and after it was set I picked up the shower drain from the plumber as the rough-in hole just didn't look big enough. Sure wasn't, and I had to pull the shower base out and cut it bigger. Pushed it back ready for the plumber to 'plumb' in the drain. When he came, we still had to lift the shower base up to secure the shower drain nut, as there wasn't room to turn it tight from below. Seems this is the kind of surprise that could have been addressed sooner, but one trade doesn't like to do for another trade as I see it. Pretty inefficient.
