What you need is a garden hose 'Y' to go on CG water spigot. Then you can hook up your 'water pressure regulator' and 'portable water supply hose' on one side of 'Y' and a 'general purpose hose' on other side of 'Y'
Portable water hose..........ONLY connects to RV city water connection. That is it ONLY use
General use hose.......flushing/rinsing macerator, sewer 3" slinky hose, spraying errant kids down with etc.
Good Brass 'Y' not one of those cheap green/yellow plastic junk

AND if your 3" sewer slinky hose doesn't have a fitting on end that goes into CG sewer pipe get one of these.
It has different size threads and screws into most CG sewer pipes

Until then....use sewer hose. Stick end in CG sewer pipe and stuff rags around it. Hold it down into pipe with foot while dumping.
OR fill fresh water tank.use on-board pump. Disconnect white hose from rig and spigot----connect black hose to spigot and to flush system. Turn on macerator and dump. Then turn on flushing system and flush black tank and macerator. When done with black tank. Turn off flushing hose, close black tank drain valve then open and dump grey tank.
