Recommendations that can avoid a visit from the plumber over the holiday:Never pour fats or cooking oils down the drain. They solidify in pipes. Instead, wipe grease from pots with paper towels and throw in the trash.No stringy, fibrous waste in the garbage disposal ( poultry skins, celery, fruit and potato peels). Disposals cant sufficiently grind these items.Make sure disposal is running when you put food into it. Don't wait until it's full to turn on.Wait ten minutes between showers so slow drains have time to do their job.Never flush cotton balls, swabs, hair or facial scrub pads down a toilet. They don't dissolve and they cause clogs.If you need a plumber, call before the holidays to avoid delays and holiday service charges.
