A plumber was scheduled for early Friday, but he didn't come to work. We were facing a weekend of clogged drain in the kitchen - max inconvenient. We were very fortunate Tomas came to our rescue, unclogged the piping, replaced the failed disposal, and also made a modification that allows me to open the piping and do my own unclogging, if needed. A friendly, courteous man who took care not to track snow into the house.
