I would like to start off by calling myself a bone head. So I bought a house with an inground pool having never owned a pool before. Well, I opened it last weekend unplugging the skimmers and filling with water and chlorinating the **** out of it. It has gone from green to cloudy blue/white and I am waiting for my TF100 kit. It occurs to me today at work that I never pulled the main drain plug so I get in and swim to the bottom, feel around and sure enough there is a plug there. 2 problems: 1 I can't see the plug to get a good idea how to remove it and 2 being 9.5 feet down means I have about 10 seconds of air in my lungs to work with it after I get down to the bottim and find it by feel. It feels like a standard rubber plug that loosens after you unscrew it but there is no wing nut, just a long hex head bolt coming out the top. I have scoured the site looking for pictures of main drain plugs, but to no avail. Any suggestions for my stupid butt?
