Subfloor drains

[rippie]

I put drains in the rear c channel where I have been doing repair work. But before I lose access to the top of the plywood subfloor, I thought it might be a good idea to place a small drain hole in certain high risk spots (under black tank, hot water heater, tub drain, and other areas with many plumbing connections). Any ideas about this? Photo shows channel drain on far left (red).

Are you placing some sort of mesh to stop bugs from getting into the walls over the drays? Also does the belly pan not cover up all those black tank handles?

I hadn't thought about a mesh. I may place something over the bottom of the drain. I wanted to keep the upper point low to encourage drainage. I have not yet gotten extensions for the valve handles yet, but will soon.
And about drains in the ply?
And, by the way, should there be another outrigger back in this area(rear street)? I know there is all this plumbing stuff there, but the weight of the tank would seem to warrant it. Looking at the frame, I don't see evidence of one. But I could add one if recommended.

The way I look at it....if you have enough water on the inside to require a drain hole, you have other things which need more of you attention. Maybe your over thinking this whole thing. Also, in Texas bug protection screening is a must...I hate mud daubers.

By the way, the drains are all inside the belly so not directly exposed to bugs on the outside. But still a good idea to bugproof.

I know what you mean, but after doing all the repair work I have done, I think of it as minor alleviation but more of an early problem detection. The PO (and later, me) had clearly enough water to cause a problem. But I don't think it was a gusher, just drop by drop. I think it would be particularly beneficial under the shower pan and above floor tanks, the places above access is particularly difficult. I'm talking about small drain holes the diameter of a drinking straw. It's just an idea, but I was wondering if anyone else has thought about or done this. Perhaps even specifically located at the rear of suspect areas (as mine is rear bath) where they can be checked periodically by jacking up the front of the trailer. I will be making some plumbing modifications (you can see how confident I am in my work).

Put in a moisture sensor to let you know you have a problem.

You're not a fan of my low-tech moisture sensor?
How bout my low tech smiley? ; )
