[2022] Pipe leak created a massive waterfall on my lot

I actually can't find any mail related to this over at support at all, so not sure who you have talked to, was it on discord?

The only way to get rid of that water is by filling it all up with blocks, though after disabling anything that could spill out water regularly. I'm aware of an issue that can cause this and it's being worked on for next Update, but your specific descriptions sounds quite different. Screenshots would indeed be helpful as well.
