If you cook often, then you most likely have this problem more than anyone else. Potato peels and stringy vegetables along with a few egg shells can be your accomplice for clogging up the kitchen sink, as they are the number one cause of stoppages and back ups. Other things such as grease and shoving large quantities of food down the food disposal can also cause problems. In many households, it's not just the stoppages and back ups that are the problem. If food is backed up, creatures such as ants, roaches and even mice/rats can invade your home and target that clogging. That is surely nothing you want to wake up or come home to. Free Estimates.
