Quoted from Foxxstone_80:It's against city ordinance in my area to discharge sump pump water into the sewage system. I'm sure many people still do it though.
We “had” to change our homes (built in the 50s) discharge path when we had a sewer main issue as the contractor said it was out of code going to the sewer line. They claimed that occasionally the city inspectors release colored smoke into the local line and wait to see which homes report it to fine them. If they didn’t need to tear up the whole yard to rerun the line, I probably would’ve left it alone; but, it was as good of a time as any to do it.
Sorry to hear about the basement flood. That always sucks. Thankfully the only water we ever had in our basement was from a water heater leak. Unfortunately, it wasn’t able to drain over to the sump even though there was a drain right in front of it because the line was clogged. It turns out when we had the original water softener from the house replaced, they tipped it over to let some of the water weight to drain and ended up clogging the line with the silica. Always a good thing to check those drains to your sump are clear.
I never heard about the water powered sump backups, so thanks for sharing that. I’ve got a battery backup; but, will look into this as well. Seems simple enough.
