If your toilet periodically runs or makes a hissing sound, water is slowly leaking from the tank into the bowl. This is almost always caused by a worn-out rubber flapper, an improper chain length that keeps the flapper from sealing, or a faulty fill valve. Flappers degrade naturally over time—especially if chemical drop-in bleach tablets are used in the tank. Replacing the flapper or the internal fill assembly is a straightforward fix that stops water waste immediately.

First and most importantly: shut off the main water valve. Every adult in your home should know where this valve is located (usually near the water meter, in the basement, or where the main line enters the house). Turning it clockwise stops the flow and limits water damage. Once the water is off, open an outdoor hose bib or lowest faucet to relieve residual pressure, turn off power to your water heater if it's involved, and call a licensed plumber.

We strongly recommend avoiding harsh liquid chemical drain cleaners. These products use caustic chemicals (like sulfuric acid or sodium hydroxide) that generate intense heat. Over time, this heat and acidity can corrode metal pipes, warp or soften PVC, and damage pipe joints. Furthermore, if the chemical doesn’t clear the clog, it sits trapped in your pipes, creating a hazardous situation for whoever has to work on it next. Mechanical snaking or hydro-jetting is far safer for your plumbing.

A garbage disposal isn't a trash can—it's designed only for light food scraps rinsed off plates.

Never put down: Grease, cooking oil, bacon fat, coffee grounds, eggshells, fibrous vegetables (celery, corn husks, artichokes), pasta, rice, bones, or fruit pits. Fats solidify in pipes, while starches expand into a thick paste.

Safe to put down: Soft food scraps, small citrus peels (for freshness), and cold running water while the disposal runs.
