On Sunday afternoon I returned from my camping trip (Summary: beautiful canoeing on Saturday and lovely friends who sat with me under tarps in the rain the next day) and went down to the basement to deal with the mold. While I was down there formulating my plan, I realized the basement sink was flooding rather than draining. So I reprioritized and spent the next two days trying to clear the drains. And I was 95% successful. Taking apart the drain didn't work, so I had to cut into the vertical drain PVC pipe, install a Y connector for access, and snake the pipes. See that lovely degree Y and access cap? I installed it, and the drain, well, drains now. I must admit that there is a teeny tiny drip where I installed it, which is why I only give myself a 95%.
While I was working on the pipes, I realized that my furnace was gurgling. Furnaces shouldn't really have anything, ever, to do with water, so this was more bad news. I have again reprioritized my home disaster list, and will try to solve the excess water from the A/C problem tonight. Hopefully I can start on the mold tomorrow. And if I'm lucky, it will finally stop raining by the weekend so I can put my damp tent out to air. Please send very dry thoughts my way.
