Sump Pump Discharge

How can I protect the outlet of a sump pump discharge to the exterior so things don't back up into it or a rat doesn't decide to setup shop?

Most sump pumps use a 1 - 1/2 inch outlet pipe, or possibly a 2 inch pipe. That is what I have on my system, and I run it directly into a 5 gallon bucket with 1/2 inch holes cut in the sides. The pipe actually discharges into a few big rocks on the bottom of the bucket, works fine, no rats. If you are really concerned, you can buy a plastic housing to cover the outlet that deters rodents.

Put an adapter on the end to connect to a slightly larger diameter pipe, and then put screening on the larger diameter open end. Use 1/4 inch wire mesh rather than window screen.

An adapter with a screen like AllanJ mentions is your best option if your really that concerned about pests entering your discharge line. As long as the pump is cycled once a month, you won't have any problems, and if something does get in there, the next time the pump kicks on, it will be "evicted" in no time!

What about snow? My sump currently empties into the waste stack, so I have not had the pleasure. We did have 30" here last year and the sump ran quite a bit.

The waste stack for Town sewer ?
That's a violation in most areas, here its up to a $1500 fine
