What causes stoppages?
Misuse of toilets by flushing wrong types of products. Drains are most often clogged with a buildup of grease and/or soap. Some foods to avoid putting down the kitchen garbage disposals are grease, rice, pasta (any starchy foods), onion peels, egg shells, and stems from flowers. Also, separation of pipes due to ground movement or age of system can cause stoppages.
