Ok I was running my kitchen sink at a slow pace to keep it from freezing up here in Memphis yesterday. I woke up this am and the tub was full of water and came out onto the floor. I took buckets and got the water out of the tub but the drain is still clogged. I do not use the shower at all and am wondering if I am missing a drain or something and that is why it backed up. Please any help on this would be appreciated.
