Outdoor Sump Pump....
Has anyone come across this before? The house was built in 1959, a ranch w/ a full basement. There is a walk out basement door to stairs w/ block walls, the lot is flat. Coming through the walkout door there is a 4'x4' landing that has a sump pit dug into it. There is a single drain pipe running to the pit, from the drain in the basement floor near the washing machine. There are also drain pipes on either side coming through the block walls of the exterior stairs, fed from french drains along the foundation presumably.
I'm mainly curious if someone has come across this before or would be willing to guess why this sump pit was dug outside, as I said it is the only sump in the house. Was this a retroactive fix?
What kind of issues should I be worried about? Right now I'm thinking debris getting into the pit/pump/piping. How concerned should I be about a hard freeze? Im in Ohio. If the sump pit is frozen I wouldnt expect that any water would need pumped, I dont know if this will damage a pump though. The plumbing is set up with a check valve at the highest point so I dont think the pipes are in danger of freezing & breaking.
I pulled the original pump out and replaced it with a sewage pump in an effort to handle the leaves, acorns, etc that might find their way into the pit. I also ran 2" PVC again to better handle any debris going through the line.
