Exterior "shoe" Storage Locker Leak | 22R

[Cham20]

Hi gang,


I've been reading through a bunch of the "leak" posts on the site, but I haven't seen anything that quite resembles what I've observed.


This is the exterior locker to the left of the side door (which would be below the kitchen sink) that I'm referring to.


Over the last several months of constant use, we have seen up to an inch of water accumulate in this locker.


I've checked under the sink and see no signs of water there. Additionally, we've had the lines blown out for the winter, so I don't think what I'm seeing now is from a sink leak.


Without having driven in the last few months, I'm seeing what would be best described as condensation in the locker.



In giving the locker a close look, it gives the impression that somehow water might have pooled on top of the locker and cause corrosion that might be causing this.


I'll be re-caulking the whole thing shortly, but I'm wondering if anyone has had water accumulate on top of the locker before, and what did you do about it? I can only assume that it is from road spray from some of the extended driving we have been doing?


Thanks for your thoughts!


Edit: Added a few photos (though they aren't great, they do show the corrosion on the top of the compartment).

I had a similar problem where the water pump connection had failed. The water pump was just above an exterior compartment and gravity delivered it there.

I replaced the pump and in all about 4 fittings that looked, suspect. I also replaced my city water fill valve while I was at it. Both water heater check valves were replaced earlier in the year because of an irritating chatter.

These actions fixed my problem. I used Sharkbite fittings to include "push to connect" as well as pinch crimps.

Thanks for the link to those plumbing diagrams. Those could come in handy!
