Answering a couple of questions about my leak:
This is using the pump. I rarely connect to city water.
I tried the paper towel trick, but I have never caught it in the act. The towel is either completely dry or soaked. I tried putting a little tray under the pump. It does catch the water, but I can’t tell if is inlet side, outlet or the pump itself.
This is a brand new trailer. We saw the leak 3 times on a 10 day camping trip. The pump was on the entire time. It may be that the leak only happens when the water heater is on, but still not every time. The heater is nowhere close to the leak.
I’ve seen the leak twice in the week since the trip. Both times it happened like this: I decided to shower i the trailer to see if that caused the leak. I turned on the hot water, and waited. When I went back out, the spot was already wet. Dried it off, took a shower, and checked it again. No additional water after the shower.
In order to post a picture, I need to put it somewhere else on the web, and then link to it, right? I’m not sure where to put it.
