Recently purchased a Moody 42 (my wife's pick)and having some issues with access to things such as plumbing and wiring. The plumbing in particular. Since I can't aget to all the plumbing lines (behind molded in fixtures) I am having trouble deciphering exactly how all the lines tie in together. There are several throw valves and inlets (as well as discharge thru hulls). Since Moody does not supply a diagram of all the plumbing, does anyone have a suggestion on how to get access to the hidden lines behind the molded in fixtures without access points such as sinks etc? Thanks for any help Daryl
