I have an '06 landmark and both the grey #1 and #2 valves are now sticking and won't close properly. I have had the underbelly cover off and know where the #1 tank is but can't find the #2 tank (kitchen). Any help is appreciated.

Hi bobday55,

Welcome to the Heartland Owners Forum. If you start at the sewer outlet, you may be able to see where the 1-1/2" drain pipe joins the 3" sewer pipe. The gray #2 valve will probably be pretty close to that junction.

On our 2011 Rushmore, I had to cut an opening in the coroplast to get to the gray #2 valve. It's about 1 foot to the rear of the drop frame and about a foot or so inward from the frame on off-door-side.
