HomeOnWheels , I hope I do not run into problems posting this picture but it clarifies the plumbing...the area below the shower in the W looked at from the rear.
When you remove the plastic cover underneath the fresh tank you should see 3 hoses - the fresh water drain and 2 low point drains for hot and cold water. In my case they are all white as they are in the picture, if you look closely where the blue and red hoses exit the coach to underneath the ends are clear (white) but are just extensions of the red and blue...
The 24r had the low point drains underneath next to each other right next to the steps, the low point drain in the left rear compartment.
