    Black Tank Valve Replacement

    We will be replacing the black tank valve in our 2019 303 RLS. Looking for information as to the location of the valve. Would like to cut the coroplast in an "X" and/or "H" pattern in the valve area and not sure where to start the cuts. We have looked online for a plumbing schematic and can't seem to find one.

    Thank you for any and all advice if you have walked through this fire on a 303!

    You may want to consider dropping the belly cover instead of cutting a hole. Once you cut a hole you will always have a hole to keep sealed, you will not be able to replace the valve without some leakage and working through a hole sounds like a pain. I replaced the kitchen gray valve on my Reflection 337 by dropping the belly cover back to the steps to access the valves.
