So I'm about to install a new toilet and I had to tighten down a screw on the mount ring and as I bend forward, this screwdriver extension which I believe was about 3.5 inches falls into the 4 inch drain. I hear it slide all the way down around corners to the basement. No way to get it out of there. My hope is the thing washes out to sea and doesn't get stuck some place. Anybody?
