Our kitchen sink started clogging about a year after we moved in and has gradually gotten worse. At the beginning it stops draining when a lot of water is poured down the drain, now its water "tolerance" has gotten smaller and smaller. The strange thing is we tried everything from Drano to plunger, and they simply didn't work. We even took out the garbage disposal and looked inside, nothing. We had a plumber look at it and he used electric cables of all sizes and lengths with no results. We bought the strongest draining solution recommended by the Home Depot guys, poured down half a bottle, left there overnight and a day. STILL nothing. The house is old but was remodeled about 4,5 years ago. I called up another plumbing service guy who said the only solution left is to dig up the floor and everything to look at the pipes because they have rotted. I truly hope that's not the case. Does anyone here have any ideas about this? ANY input would be great!
