The idea is not fancy, nor is it high tech, but boy will it save you some frustration and money…use inexpensive drain screens (made of either plastic or metal) in the kitchen sink, the bathtub, and the shower. This is the heart of preventative plumbing at home as it helps prevent food particles, hair, or small items like jewelry and toothpaste caps from entering the drain.
These screens will catch and hold hair, soap slivers, and other potential drain-cloggers and make it easy for you to lift out the obstructions and toss them in the trash before they cause costly backups. Don’t let the ease of this solution doubt its ability to help. It works! Give it a try.
