I have a Prowler P289 and after having it out this weekend I drained the what I believe are the low point drains, but my question is that it appears the "red" line was the regular water lines, and the "blue" seemed too be the hot water, it wasn't completely hot because the hot water heater had been off for a couple of hours, but it did take a few minutes too drain and the water was warm. My question is does it hurt anything that the "blue" hose is hot??? There isn't anything special about the "red" hose material?? I can live with it, but kinda makes ya think how they could be plumped in wrong
