So what hose gets used at the dump station, could the potable hose be used with an backflow prevention device? And if so, what if the source is non-potable, does that contaminate a potable hose?
Basically, you want to keep your pot. water hose away from the sewer hose. You don't want the black water to come in contact with the hose you use to put water in the rig. Bacteria will be ingested into the water system and grow in the warm stagnant periods when not being used.
Some people have a separate hose for rinsing the sewer hose, some people just don't let the potable water hose make contact.
Most dump stations have a hose you can use.
