The kitchen sink stopped draining today, we just moved in to this house about a month ago and it worked fine. There is two sinks connected and no dishwasher or garbage disposal. My fionce replaced most of the bottom part after the T since it'd began falling apart. But now it still won't drain and when we began to use a plunger dirt has begun to come back up the pipes! What do we do? It's to late to call a plumber!
