Hey Kari:
Rat here. I'm very glad he found the obstruction. Since your trouble began in the guest bathroom, but they clog was found 15 feet from the house, I wonder if the original clog was in the guest bathroom and part of that broke off and ended up down line. Did handy man have any idea what the original clog was made of(hair, Greece--whoops that's too big, I meant grease, shouldn't my voice recognition software know the difference? poo, little toy boat, sanitary you know what's?). What you need is a cultured yet obedient sewer rat, but don't look at me as my swimming days are over(unless I have a life preserver). Anyway, don't let me give you any ideas that could cause you any grief. But, if the obstruction is organic, another pals suggested lots of hot water. Something to consider if you have any spare time, ha, just kidding. Sorry, maybe I can do better with daughter's situation. When teenage son, Chris was a senior, he and girlfriend(she was driving) were run off the road and hit a telephone pole. The car should have been fully covered, yet we had only retained liability, and it was totaled. The good news: she was\is Wonderful, and they are now married and unbelievably happy, soulmates. Your day can only get better.--JK
BTW-if it's a little toy boat, see if any of your neighbors have a G.I. Joe.
