Gray Water Dump Mod

This was done by the Previous Owner (PO) so all I've got is photos. I gather I've got it pretty good inheriting this mod...

Interesting; thanks for posting. It appears he took out the larger diameter drain pipe to install that drain valve. Not sure I'd want to do it the same. I'd prefer a slice valve of some sort, similar to what's under my van currently, but one that works with the larger diameter pipe. I also think that the current system on SMBs is asking for trouble in sub-zero temps: you're storing water outside your van that's gonna freeze and break stuff.
