Fresh water tank drain location

Hello everyone.
Im brand new to this RV thing. My wife and I just purchased a Forest River Class C Motorhome, Model 21QB. Could someone help me in locating the drain valve for the fresh water tank. I would like to clean and sanitize the system, however i just can't find that valve. Thanks!

Welcome to the Forum!

The fresh water manual fill port (not nescessarily the city water connection) will be very close to the location of the fresh water tank. The drain has to be close by...the drain valve maybe underneath the camper. If the water tank is accessible within a compartment, the drain valve may also be there.

Have you looked under your rig about the same location where the street water goes in. I t may look like a white twist valve. Here is mine from my 5th wheel.

As stated they are usually hanging down underneath the rig. Mine is a 1/2" blue hose with a 1/4 turn plastic valve on it. Same goes with my low point drains.

Mine is just a turn off cap at the bottom of the fresh tank on the same side as the fill cap is located. My low point drains are the same. Old Guys

I have a 2010 Forrest River Freelander Dreamer 30' QB. I empty the tank with three "INSIDE" valves next to the water tank that drain straight down to the outside. Turn the valves so they point toward the supply line, in-line with the pipe. Attached is a picture that I hope helps.
