When hosting backyard BBQs, be mindful of what goes down the kitchen disposal. Most disposals have a tough time processing fibrous food like celery or banana peels, and that can lead to disastrous plumbing problems. Also avoid fats and cooking oils because they can cause stubborn clogs in your pipes. Same goes for eggshells and cornhusks – don’t let them go down the drain! If a troublesome item does get by, flush it by running cold water at full pressure for 10-15 seconds.
