I drained up to 6" yesterday, so when I got home, I started draining again. Now granted, the whole time driving home from work, I was trying to beat the storms that were rolling through the dallas area. No sooner then I started draining, the flood gates opened, and now my pool is back up 3" in just 45 minutes. The rain was so hard, the water from the porch almost came into the house. They are calling for heavy rain through Saturday, so this drain is going to take a very longggg time...Don't worry, its still draining..
