What causes a garbage disposal discharge pipe to clog?
Water flushed down through the discharge pipe of a garbage disposal will sometimes fail to drain because this pipe is clogged. In addition to needing to unclog these pipes you can also help prevent future clogs by determining the cause of your clogs. The following are some causes of clogging:
Water is needed to flush ground-up food down the drain. If the water flow is too slow, this food will fail to drain.
Tiny granular particles from ground up egg shells and coffee, get stuck in the pipe as sludge and cause clogs.
Starchy Paste or Fibrous Materials
Paste created from ground up, starchy potato peelings as well as celery or other fibrous foods will also clog your drain.
