The way Randy and I both do loading dock pumps is like this:

A 1-1/2" or 2" conduit is run from the sump to a location where the trailers (hopefully [Linked Image]) won't hit it. It's rigid conduit where it must be exposed (this one was an existing building). The sump pumps are available with looong cords on them. Cord and plug are pulled right through the conduit.

This one tested out great! 10 HP and pumped like crazy! Unfortunately, there was a little problem with the concrete/paving crew and their grading.

[Linked Image] The water in the first pic is coming from the pump's discharge. It runs right back into the sump. [Linked Image]

(Thx for letting me hog in, Randy)
