"Northern basements was able to fit us in quickly, pulled our crooked cement wall back in-place and sealed the wall to prevent future leaks.  The work was timely, communication was friendly and detailed, and price was as to be expected for the large amount of work that needed to be done.  We are very pleased with the whole process as well as the results.

French Drains FAQs, answered by experts

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.

Common drain issues include slow-running drains, whether in a sink or shower, clogged drains, a bad smell, and water backing up into a sink, shower, or bathtub. Causes range from hair, grease, roots, or toilet paper clogging the drainpipes to flooding outside the home, which prevents sewer lines from draining properly.

If you drop jewelry down your sink, it can cause a clog, especially if it accumulates other debris on its way down. However, that is the least of your worries if you drop your favorite jewelry down your drain. If your gold band goes tumbling down the sink drain, don’t panic—refrain from running more water down the sink, and follow the steps above.

You can pour hot water down your gutter drain to melt ice and keep ice dams from forming. If the problems persist, consider investing in heat cables to run in your gutters. Heat cables can adjust based on the surrounding temperature to keep ice thawed.

Drain pipes carry wastewater from sinks, toilets, showers, and other fixtures to the main sewer line. They’re typically located within the walls and floors and beneath a home’s foundation. Meanwhile, sewer pipes transport collected wastewater to a septic tank or a municipal sewer system.
