-Where does the pipe go from the valve at #1, (you said shower was to left, just verifying doesnt go out side)
-Where do the pipes go at #2, or are they just looped making a return just beyond picture, or is one going outside, the other up from something (sink or vent)
-The pipe at #3, Thats a large hole, is tank behind that?
If not tank then drain from kitchen?
-The angled pipe at #4, any idea where that goes (i guess vent also)
Ya know Ive been assuming 2 tanks-looking at this picture with no other info only one tank (IF it even has a tank)?, some one replaced, or at least replumbed, for what ever reason lack of correct fall the kitchen line will flow into shower if valve open, Im assuming valve is inbetween shower and one of the lines at #2 lead outside. Sure would like to see exterior valve and how you dump.
More than likley Im 180° off
Turning the handle (#1) will do nothing, it is a push to close, and pull to open.
