Casita water leak

[Larry Singer]

Hi Michael P,

I wish I had an answer. This is very annoying. You wouldn't believe all the experiments and tests I've tried to solve this.

But here's one glimmer of hope:
Last fall when I was flushing the hot water tank after removing the anode rod, I noticed water on the INSIDE where the past leaks went. I don't know how this could be. Perhaps in spraying water, I inadvertently sprayed water into the leak area. I still need to investigate this further.

Let's keep in touch, and between the two of us, perhaps we can put this to bed.

Thanks for reaching out to me.

Larry

I have a Casita.I sold my Scamp several years ago

Although the water was located on the opposite side (passenger side) and under the bed platform, I was also wondering if it came from the water heater shroud or where the electrical cable runs out. Both of those areas look like rain could easily get in. I think the water heater shroud looks to be two pieces and I'm thinking the water could be coming in where the two pieces are fused together. I'm going to seal the bottom of the shroud and see if that helps. I also plan on switching the electrical cord to a removable cord like what is used on boats so that hole doesn't allow water or mice to get in. I've also wondered if the water is coming in where the two fiberglass shells are glued together.

I haven't felt water in the walls so that makes me think its not coming from the roof or the windows and probably not from the fiberglass shell seem but who knows. I'll keep you posted with what I find.

Thanks, Michael.
Let's keep exploring.
I'll be so satisfied when we solve/fix this !

I have read this discussion with great interest.
I have a 2005 Casita Spirit Deluxe and live in Oregon. While de-winterizing and testing everything before the first camping trip of the year, I found water one morning on the floor after having the water system pressurized overnight. The search for the source lead me to the fresh water filter behind the kick panel in the back. I cleaned everything up, replaced the filter and thought all was good.
The next day we drove 3 hours and when we arrived there was brownish water on the floor. It looked like it had run from the back forward. It had been raining as well. Needless to say we drove home the next morning to dry everything out. The carpet along the back and side where the water tank resides was wet. The other side, not bad at all. I removed the water tank to make sure that wasn't leaking and it seems OK but it was wet under the tank as well. I also noticed a drip from the rear table post under the Casita.
Now I don't know if there is another leak or there is water trapped in "the bathtub" under the flooring. If it's water trapped how do I get it out? Remove the table post mount?
One more note, we are starting to feel a bit of softness in the floor near the refrigerator. Don't know if that is related or not.
Oh boy, what fun. Any suggestions would be appreciated.
Thanks

Not a solution but the Casita bath tub design is flawed IMO. The Escape and Trillium designs use a perimeter pontoon system which can not only catch leaks, but also provide drains, before they reach the imbedded plywood floor.

All the best finding the leak! Don’t miss the Casita we owned.

The leak we are experiencing in ONLY after exposure to rain. Without rain, there is absolutely NO LEAKS. Therefore I deduce that the plumbing system is NOT the source of the leak.

This is all documented in great detail on this forum. I THINK it is part of this thread. If not, it's in another related thread.

I just wanted to distinguish between leaks due to plumbing, and leaks other than from plumbing., as in our case.
