I had water dripping from the belly of our 3820FK, when I removed a couple of panels in the basement while searching for the source, I discovered about 2 inches of standing water on top of the coroplast. In our model the ant siphon valve is located in the kitchen under some drawers and that was the source of the leak, with a slow drip from the top of the valve. I’ve read that these valves are cheap and typical builders crap so I ordered and installed a Valterra valve and it’s doing the same thing. What am I missing or what would cause this.
