Randy,
Would you like to explain these pics?.

Hiya Mike =)
Pic 1 is where the conduit run that was installed was mangled by semi trailers... The run was installed ironically at the same height as the crash bumper on the semi trailers
Pic 2 I tried to get a shot of the wires coming out of the wall... there's a 4S box on the opposite side of this bell box and nothing put a hole in between.. Camera phones dont always focus on what you'd like them to...
Pic 3 Ditto
Pic 4 is where there used to be a PVC Schedule 40 stub entering the ground going to the sumps.... The marks on the wall show where damage occurs here....
Pic 5 Shows the Semi's bumper height in line with the look really close ½ inch emt strap on the wall....

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 ) 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.



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

(Thx for letting me hog in, Randy)

In general, cords are to remain visible their entire length.

Pierre

useally true Pierre but you need some kind of protection from damage as well .

up northen area where it subject to frezzing some loading dock we have outside pit but we have second pit located in the building where the frost dont hit at all and that pit is lower than loading dock pit so the water can drain out and dont get frozen up and sump pump size can varies alot depending how big the loading dock and numbers of door is the last one i did work not too long ago have 7 1/2 hp sump pump it really pump alot of water thru pretty good


Merci , Marc
