French Drains FAQs, answered by experts

A washing machine should drain the water used during its cycle through a drainpipe and out through the house’s plumbing. This is the same plumbing that sinks and shower drains run to, and if the U-bend is installed correctly, it shouldn’t smell. The total drainage from the house is then integrated into the city sewer system or, if you’re in the country, dispersed into a septic tank.

No, it is not advisable to spray pesticides down the drain in your home. Most drinking water and wastewater treatment systems are not properly equipped to remove pesticides. Should pesticides infiltrate waterways, they can cause harm to plants, fish, or other living things. In most areas, pouring pesticides down the drain is illegal due to the potential harm it causes. 

The first rule of plumbing is nothing but water, toilet paper, number one, and number two go down the drain. 

To prevent clogs, get yourself:

  • A compast pail where you can clean plates, drain grease, and toss scraps and paper towels. 

  • Drain screens for the shower, tub, and bathroom sink to stop hair, jewelry, toys, etc. from going down the drain.

  • Trash cans for everything that shouldn’t go down the drain, like dental floss, hygiene products, and cat litter.

P.S.: If you do drop your priceless ring down the drain, take a deep breath, and then follow these steps to retrieve jewelry from your drain.

Bleach—even diluted bleach—is not always the safest option for cleaning your drains. With a high pH, bleach can be highly corrosive to many types of pipes, especially when used regularly. When mixed with household cleaners and organic waste, it can also create dangerous chemicals. Remember to use proper protective equipment and ventilation when dealing with bleach.

Your sewer line can get grimy quickly. To prevent sludge buildup in your sewer line, pour a mixture of 1/3 cup of vinegar and 1/3 cup of baking soda down each drain in your home once a month. After about 30 minutes, flush the drain with hot water.

Some plumbers recommend 3/4 cup of bleach instead to clean any germs and bacteria that may build up in your sewer line. But this won’t break down any active clogs, and it cannot be combined with vinegar, as the mixture will create a toxic, hazardous gas.
