Stop a dripping faucet with washer replacement
🟢 beginner 🔥 high Impact
Replace worn rubber washers in compression faucets by shutting off water, removing the handle and packing nut, then swapping the old washer. Most drips come from a 50-cent washer that takes 10 minutes to replace.
2
Clear a slow drain with baking soda and vinegar
🟢 beginner 💪 medium Impact
Pour 1/2 cup baking soda down the drain, followed by 1/2 cup white vinegar, then cover with a wet rag for 15 minutes. Flush with hot water to dissolve minor clogs naturally without harsh chemicals.
3
Fix a running toilet with flapper adjustment
🟢 beginner 🔥 high Impact
Lift the toilet tank lid and check if the rubber flapper is sealing properly. Adjust the chain length so it has slight slack when flapper is closed, or clean mineral buildup around the flapper seat.
4
Unclog a toilet with dish soap and hot water
🟢 beginner 💪 medium Impact
Squirt liquid dish soap generously into the bowl, let sit for 20 minutes, then pour a bucket of hot (not boiling) water from waist height. The soap lubricates while hot water helps break up the clog.
