I began winterizing my 5th wheel and I can't find the low point drains. I have one drain underneath with a valve that empties the Potable Water tank. I have a Potable water tank overflow tube underneath on the passenger side with a sticker that says Low Point Drain but no shut off valve. I know this is the Potable overflow tube because I've overfilled the Potable tank and that's the tube the water comes out. I have another overflow tube next to the Potable Water drain and I don't know what it's for. Nothing has ever come out of that tube. Probably Gray tank but not sure. Neither overflow tubes have valves. No other drains are under the camper. Any ideas where the low point Hot and Cold drains would be?

Look for a valve, probably with a handle you pull up, in a cabinet or behind a removable handle, inside, directly above where the tube is.

Mine are just two pieces of pvc with 1/2 in plugs on the end that barely hang below the bottom of the subfloor. They are both located near the lowest water pipe in the trailer. In my case near the hot water heater.

Looks like it would be real easy to remove a few screws and drop the belly down enough to see where the hoses go.

mine are color coded red and blue. Not sure if all trailers are or not. Even the hose tails hanging under the trailer are color coded.

check the wheel wells....one of mine is there. It is for the fridge, but I never had one there before until now.

Understood but your best information will always come from someone who owns the same unit as you. Of the two fifth wheels we have owned, one had drain taps in the right side basement and the other underneath, just behind the left side of the rear axle. They can be anywhere.

That's true in most instances wilber and I agree with you. I was just seeking ideas on where to look. Maybe some obscure location I wasn't thinking about since I had crawled under the camper and didn't find them. In this instance, they weren't easily spotted. I've learned from the dealer that even within the same manufacturer and model, they can place those drains in different locations and have different amounts of tubing exposed. That might explain why the low point drain sticker is 15 feet away from where the drains actually are and they stick down beneath the coroplast all of an inch. In any event. my issue is resolved.
