Hi all, brand new to travel trailers. I noticed 3 water lines exiting out through bottom of trailer by water heater tank. Are these drain lines for water heater? Or for the plumbing system? Thanks.
2 of them are low point drains: 1 for the hot & 1 for the cold. The 3rd is for the water tank. The water heater drain in behind the access panel to the water heater on the outside of the trailer.
