French Drains FAQs, answered by experts

Food grease, soap buildup, paper products, and tree roots often cause serious clogs.

If you try a drain snake and various DIY methods for unclogging drains to no avail, bring in a professional plumber to assess the situation. Also, if multiple drains in your home are backing up or you smell sewage, a visit from a plumber is best. You can expect your drain cleaning costs to fall around $250, and this can include an assessment of what’s caught in your plumbing and if there’s a larger, underlying problem. You should also consider calling a pro if you need to snake a toilet, as DIYing this could lead to a cracked fixture.

You can try several easy methods to unclog a drain, one of the easiest and most effective of which is to use a mixture of baking soda and vinegar. This will help dislodge and dissolve the clog to move it down the drain pipes. Pour 1/2 cup baking soda into the drain, followed by 1/2 cup of white vinegar. Dump several cups of boiling water (or hot water if you have PVC pipes) into the drain and let sit for up to one hour. Run hot water to clear the drain.

No, you should not see water in a sewer cleanout. If you do, it could indicate that you have a block or leak in your main sewer line—which can cause sewage to back up inside your home and potentially flood your yard. Your best bet is to call a local sewer cleaner if you notice any water or sewage around your cleanout.

There are several homemade solutions for clearing a clogged sink that don’t involve pouring harsh chemicals down your drain. Start by pouring hot (but not boiling) water down the drain. This can help dissolve and flush away grease and gunk. A splash of dish soap down the drain can also cut through fat and make it easier to clear the drain. For a more stubborn blockage, grab a plunger and give it a few firm pumps to dislodge the clog.
