Sewer ports Mallard M28

[Pete032]

Am new to RV’ing and we just took our first trip This past weekend In hooking up the sewage hose Which has two port levers One is for Gray the other is for black I also noticed that there was a second port towards the middle of the trailer also. This has a shut gate on one side. To be safe because I had a hose extension I hooked both up when it came time to dump the tanks liquids came from both does anybody know what that middle one is?

Hi Pete032,

Welcome to the Heartland Owners Forum.

Another owner with an M28 can probably tell you with certainty, but with your floor plan showing 84 gallons gray tank capacity, that's usually going to be 2 gray tanks. One would be for the bathroom and the other for the kitchen.
