Don’t use chemicals to clean a clogged drain. Use a plumbers snake and follow
these tips to prevent future clogs.
Clogged drains are the most common home plumbing problem, but you probably don’t think much about the
network of pipes inside your home’s walls until a drain stops working. Clogged drains are a hassle, but easily cleared.
However, you can avoid the hassle by paying attention to what goes down your drain. A little care prolongs the
life of plumbing pipes, prevents leaks, and avoids costly repairs.
Avoid chemical drain-clearing products
You can buy chemicals to clear clogged drains, but these products sometimes do more harm than good. They can actually erode cast-iron drainpipes. And because they typically don’t remove the entire clog, the problem is likely to recur, causing you to use the chemicals repeatedly. The caustic action of chemicals may eventually wear away the insides of pipes, causing leaks.
Better to hire a plumber to snake the drain (usually $85 to $325) and completely remove the chunk of hair or grease that’s plugging the line.
Better still (and cheaper!), pick up a manually operated augur, or snake, of your own, for about $15 at the hardware store. Or, rent an electric snake for about $30 for a half day, and try clearing the clogged drain yourself.
Prevent clogged drains
Clogged drains aren't just nuisances. Backed up water puts added pressure on wastepipes, stressing them and shortening their lifespan. To avoid clogged drains:
Keep food scraps out of kitchen drains. 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.
- Keep hair out of bathroom drains. Install screens over drains in showers and tubs, and pull out what hair you can
- every few weeks to prevent buildups.
- Keep anything but sewage and TP out of toilets.
- Keep your sewer lines or septic tank clear
- If you have municipal sewers, hire a plumber to snake your main sewage cleanout every few years. This will cost
- $135 to $600, and will remove tree roots that inevitably work their way into these pipes leading to messy sewage
- If you have a septic system, get the tank pumped out every three to five years for $ 75 to $350; it'll be more larger tanks.
