In response to Re: Oil Filled Sump Pumps
One other reason is that since oil floats on water, if the seal goes bad the oil will prevent the water from filling the motor chamber and burning it out.

: I notice that some sump pumps are oil filled. Why is that done? Also, what type of oil is used, and how much of the motor chamber is filled? Thanks for any information you can provide.
