Clogs aren’t just nuisances. Backed-up water puts added pressure on your waste pipes, stressing them and shortening their lifespan. So avoid plug-ups by watching what goes down your drains. That means keeping food scraps out of kitchen drains, hair out of bathroom drains, and anything but sewage and toilet paper out of toilets.
Install screens over drains in showers and tubs, and pull out what hair you can every few weeks to prevent buildups. Scrape food into the trash before doing dishes—even if you have a disposal—and never put liquid grease down the drain; pour it into a sealable container to put in the garbage after it cools.
“Grease is only liquid when it’s hot,” Gove says. “When you pour it down the drain, it cools and becomes solid. Do that enough, and just like a clogged artery, your drains won’t work anymore.”
