Water pump location on a 2015 Cruiser 322rl? Help!

[lmpres]

This is my 3rd trailer and I've never had this problem. I am trying to winterize it and CANNOT find the access panel to the water pump! I've turned the pump on and can hear it behind the wall to the right of the refrigerator. There are cabinets in the wall, but I don't see an access panel. Does anyone know where it is? I had a call into Cruiser and they were supposed to email me back with the location when they could find the engineer, but didn't send it to me...

Check basement compartment rear wall........false wall?

You will need to run pump while checking inside that compartment....from roadside
