    315 RLTS Pipe Question

    This is probably a dumb question but I don't know who else to ask but my fellow GD owners. While doing some investigating of the water heater on my 2017 315, I pulled the drawers in the bedroom and exposed the back of the water heater and heater ducting that comes though the floor. It also allowed me to see(and insulate ) the hot (red) and cold (blue) water pipes that service the shower and the lavatory sink. But there are are two black pipes that come through the floor and go up the same wall of red and blue pipe for the shower. Can anyone tell me what those black pipes do, where they go and where they come from? They appear to be same 1/2 inch size as the rest of the water supply lines.

    I'd appreciate any info you might have.

    Most likely your black flush line which goes to a vacuum breaker type component and then from there to the black tank.
