French Drains FAQs, answered by experts

To unclog a plumbing vent, you first need to locate it. Look at your home's roofline. The plumbing vent will be a vertical pipe sticking straight up from the roof. Since this pipe runs all the way to the main drain underneath your house, you should also be able to find it in the attic.

Anything you drop down your sink runs the risk of damaging and clogging your pipes. Hair, bits of food, and other debris can catch on the item and build up over time, causing a clog. Even if it’s not valuable, it’s definitely worth trying to retrieve the item, or at the very least, asking a pro for specific advice.

If you have a sink stopper, it can feel more challenging to clean the drain without removing it, but here are a few simple steps:

  • Pour ½ cup baking soda into the drain using a funnel

  • Pour 1 ½ cups vinegar into the drain

  • Close the sink stopper for 15–20 minutes

  • Open the drain

  • Pour 2 cups of boiling water down the drain (be cautious as boiling water can damage some types of pipes)

If the drain isn’t unclogged, repeat the process.

Yes, flushing a clogged toilet can make it overflow. While flushing the toilet may push enough pressure through the system to dislodge the clog, this is unlikely. Your best bet is to use a plunger and hope the suction can break up whatever is blocking the pipe. If this doesn’t work, use a plumbing auger or call a pro to help.

Bleach is generally not recommended for your shower drains. Although diluted bleach can technically help clean your drain, it will not unclog your pipes. In fact, bleach can harm your plumbing system because it’s so powerful. The bleach can change the color of your sink and even corrode metal pipes and fittings.

Often, people reach for bleach because it's already in their house. But it's worth getting a plunger or a drain snake for the job instead. It'll be a lot less money to buy a new plunger than to pay a plumber to repair or replace damaged pipes.
