Nothing ruins a day quite like a clogged or overflowing toilet. Sometimes, we’re fortunate enough to handle the problem on our own with a trusty plunger. But when the bathroom floor becomes submerged in toilet water and you need to call in a plumber, things can get pretty pricey.
To avoid these unfortunate (and expensive) situations from happening, here are six things you should never flush down the toilet, along with the science of why they cause so much trouble.
🚫 The "Do Not Flush" List
1. Hair
Do you ever empty your brush and throw the hair directly into the toilet? Although many people do this, hair can clog the pipes in your toilet just like it clogs the drains in your sink and shower. Hair doesn't break down in water. Instead, it tangles together, catches on tiny imperfections in the pipes, and creates a net that traps other debris, eventually forming a solid, stubborn blockage.
- The Fix: Throw hair in the trash, or better yet, compost it! Hair is rich in nitrogen and makes a great addition to a compost pile.
2. Baby, Face, and Makeup Wipes
Baby, facial, and makeup removing wipes should never be flushed down the toilet. Even if the packaging claims they are "flushable," they have an extremely tough time breaking down, making them a serious culprit for clogged pipes. Unlike toilet paper, wipes are woven with synthetic fibers designed to stay strong and intact when wet.
- The Fix: Always toss wipes in the trash. If you want to reduce waste, look for biodegradable wipes, but still dispose of them in the garbage, not the toilet.
3. Paper Towels and Facial Tissues (Kleenex)
It’s tempting to use a paper towel or a tissue to wipe up a small spill and just flush it away, but this is a plumbing disaster waiting to happen. Unlike toilet paper, which is specifically engineered to dissolve rapidly in water, paper towels and facial tissues are treated with "wet-strength" resins. They are designed to hold together when wet so you can wipe up spills without them falling apart. When they go down the toilet, they stay intact, clump together, and create massive blockages.
- The Fix: Keep a small trash can in the bathroom specifically for tissues and paper towels.
4. Feminine Hygiene Products
Tampons, pads, and applicators are designed to do one thing exceptionally well: absorb moisture and expand. When you flush them, they do exactly what they were engineered to do inside your pipes. They swell up, get wedged in the bends of the plumbing, and create a watertight seal that stops water flow entirely. Furthermore, the plastic applicators and synthetic wrappers never break down.
- The Fix: Wrap them in toilet paper or the wrapper and place them in the trash. Many public restrooms provide specialized sanitary bins for this exact reason.
