"Iâ  ve hired Discount Plumbing for everything from clearing clogged sewer lines from my house, installing a water heater, installing a drain for my new washer room and now Mr F. Vasquez discovered a large plastic pipe wedged into a main drain. He saved us costs by his professional eye for trouble. I have called them for nearly 10 years now. Thanks"

French Drains FAQs, answered by experts

A liquid drain cleaner can sometimes make a clog worse over time if you use it improperly or too much. The chemicals in drain cleaners can corrode and damage pipes, causing cracks and leaks that may cause further blockages. If the clog is more than the liquid drain cleaner can handle, the cleaner will simply add chemicals to a bigger overall problem.

The cost to unclog a drain varies based on the location and severity of the clog. For simple clogs within your home, such as in a sink, toilet, or shower, hiring a plumber typically costs between $110 and $350, with an average of around $200. Snaking a toilet or sink usually costs between $110 and $275, while a bathtub or shower clog costs about $225.

For a more serious clog in the main sewer line, the cost is higher. Clearing a main line clog generally costs between $200 and $600, with an average of about $380. However, prices can range from as low as $100 for snaking a minor clog to over $1,600, particularly if advanced methods like video inspection and hydrojetting are needed for a large or hard-to-reach blockage. Some severe main line clogs can cost upwards of $1,000 to clear depending on factors like the cause of the clog, its distance from an accessible cleanout, and whether the pipe is located beneath an occupied space (e.g., in an apartment building). You may be able to save money on minor clogs by using a drain snake or bladder yourself.

The most common cause of a clogged sump pump is natural debris buildup. As water enters the sump pit, it can carry small pieces of debris that build up over time, or the debris can get caught in the filter. If you forget to cover the pit after cleaning the sump pump and pit, debris can also collect in the pit. Corrosion on the metal discharge pipe can also clog the pump. Additionally, if your pipes freeze, it can prevent water from draining properly and cause a clog.

It is safe to flush small amounts of bleach down the toilet. Don’t flush more than ¼ cup of bleach. Instead, consider diluting it and pouring it down the sink drain.

This depends on the location of the blockage. If the blockage is in your home’s system, anywhere in the system, it is your responsibility as a homeowner. Blockages seldom happen because of items or buildup coming from the city, which means it originates in the home. It becomes the city’s responsibility at the exact point your home’s line distributes waste into the city’s system. The exception is if the problem in your home damages the city lines.
