Hole in Foundation for well hose

[gahalifax2010]

Hello, I have a large hole in my foundation where the hose for the well enters the house and connects to the pump. The hole is approx 1 foot in diameter and opens up into a hollow space that appears to be under the foundation. The hole is located in my crawl space we use for storage and mice are entering the house here. The previous owners had stuffed pink insulation into the house but of course that does not stop mice or the draft that comes from this.

I want to plug this up to keep out the mice and drafts but not impact the hose for the well or making servicing or replacing the hose problematic. I plan to use some expanding spray foam along with a layer of steel wool. Can anyone think of a reason not to, or a better way? I did not want to get involved in using a mortar or mix if possible.

As long as the pipe is deep enough to prevent freezing it will be fine. But sometimes the 1' hole is there to allow warmth from the house to keep the pipe outside from freezing.

Any piping outside the foundation should be in the ground below the frost line. Any piping inside the foundation must be kept above the point of freezing.
Had you posted a picture of your problem area, it would probably be easier to recommend a good permanent repair.
