Hey there. New to the RV world. Bought a new pre winterized 26M Redhawk in the fall here in northern Idaho, and now that the snow has melted have de winterized it and started camping. One big problem: the water pump isn’t pumping and I can’t find it to check for air leaks etc. I hear it in the rear of the coach but can’t figure how to get to it. Where is the water pump located on a 2022 26 M?
