That makes sense too me! The red and blue line comes out from under the shower pan up to the faucet, no drain line. The carpet is wet right under where the lines bend and go up to the faucet. So the water must be running down the lines just like you mention. No sink in the shower and no drain line in the closet. Will look at it in the spring.
One side note
scamp did have many issues with the 2017 scamps. The brake wire was cut too short and broke off of my
scamp. I installed a break away switch and tested it and wheel turned freely, that's when I noticed the broken wire. I wonder how long I drove with one brake?
Thanks for you help!!
