French Drains FAQs, answered by experts

If you’re not using a septic system, problems with your home’s plumbing won’t cause this—it’s a city problem. A large blockage in the municipal sewage lines may cause those lines to back up into your home. This is extremely unpleasant and can be a serious health risk due to bacteria and other contaminants. If this occurs, call a pro (or your city) immediately.

While technically possible, it is unlikely that a clogged toilet will fix itself. Clogs caused by water-soluble materials like toilet paper or human waste may eventually break down in the water, allowing flow to resume. However, this can take time, and any clogs from solid objects require manual removal. In most scenarios, especially if you don't have another bathroom, it is best to fix the clog yourself or call a plumber.

Yes, you can pour water down the toilet to help it flush. For each flush, you’ll need 1 to 2 gallons of water for newer toilets or 3 to 5 gallons of water for older toilets. Rather than dumping the entire bucket in all at once, pour the water in slowly for the best results. If you’re pouring water down the toilet to help it flush after a clog, only use 1 gallon of hot water.

DIY plunging or drain cleaning chemicals may help minor clogs, but professional hydro jetting ensures long-term solutions.

Septic tanks can clog if they aren’t pumped every few years since solid waste accumulates inside of them. Your tank might also clog if you have a habit of flushing anything other than human waste or toilet paper. Items like diapers, baby wipes, paper towels, cat litter, and personal hygiene products should never go down your pipes.
