This represents my (indoor) pool. It came about this morning I should be able to drain it today. I set the drain time at 5:17pm. Military time would be 17:17. A couple things have to happen first to make that deadline. Just so happens adding todays date like this...1+28+20+22=71 or 1+2+8+2+2+2=17. Just thought I would mention it. This all hinges on my pool guy being on time and completing a pump repair first. We shall see!
