What does this go to?

29' 1992 Excella twin bed, Right behind where the city water comes in, street side, the pipe branches and the one with blue tape 90s into the floor just past the on/off valve. It's always been off. What is it for?

It is a low point drain, right at the start!

Is this your owner's manual?

On p. F-31 [PDF p. 107/222], at the top, the twin-bed illustration would seem to apply to your 29' IMO ["no matter what style"], even though it is entitled Thirty-Two Foot. There is an "X" right where your photo shows the valve/drain.

If you look under the trailer, you should see the blue pipe exit straight down, and water will come out of it when you open the valve.



PS -- Edit -- Oops just found your earlier thread -- still have the following manual handy?

Thank you ALL for you help on this.
I suspected it was a drain but it did not show up in my owners manual and I did not turn the page and look at the next length up. It does show it on the 30'. Looking under my AS I did not see an exit hole or tube, but I may have just missed it.
As you may have noticed there's been some previous sub-floor repair work done in that area. Anyway, since I'm replacing this sub-floor the mystery would have been solved at some point, but I really was curious and I knew some of you would know.
This old quest pipe is history also and will be replaced when I begin the rebuild.

OTRA15 (Peter), Thanks for the '92 manual PDF. My manual is also for a 92, but from location of the floor plans it's obviously different. I haven't looked further than the trailer floor plans on Pages F30 and F31 but they are different than mine which are located on pages F19 & F20. It will be interesting to compare and it will be especially nice to have this digital manual on my phone and computer.
