"Ryan was perfectly on-time and was a plumbing scholar and a gentleman. We had a simple drain replacement under a new sink. Going to Western saved me at least another day of trying to figure out proper parts and doing the install myself, and it also saved my wife's ears from hearing my salty language."

Immediate drain clog was cleared in accordance with my Angie's List coupon deal. The technician was up front in saying my old house may need more extensive service in future."

Drain Cleaning questions, answered by experts

Some homeowners use additives every month to help septic system performance, but according to the U.S. Environmental Protection Agency, the effectiveness of septic system and leach field additives is unknown. Further, additives made with organic solvents or alkali chemicals can actually be harmful to the necessary bacteria in a septic system.

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.

Your garbage disposal is not draining because it might have a clog due to food waste, a foreign object, grease, oil, fat, or it may have a broken motor. When water doesn't flush out of the disposal, that's a key sign that your disposal has a clog or needs repair. 

Bleach is generally not recommended for your shower drains. Although diluted bleach can technically help clean your drain, it will not unclog your pipes. In fact, bleach can harm your plumbing system because it’s so powerful. The bleach can change the color of your sink and even corrode metal pipes and fittings.

Often, people reach for bleach because it's already in their house. But it's worth getting a plunger or a drain snake for the job instead. It'll be a lot less money to buy a new plunger than to pay a plumber to repair or replace damaged pipes.

It is not advisable to use drain cleaner in a washing machine. Drain cleaners contain harsh chemicals that can damage the internal components of your washer, including rubber seals, hoses, and even the drum. These chemicals can also react with any residual detergent or fabric softener, potentially leading to noxious fumes. If your washing machine is experiencing drainage issues, it's best to address the problem directly by inspecting and cleaning the lint filter, checking for clogs in the drain hose, or seeking professional repair services. Using drain cleaner in a washing machine is a risky solution that can cause more harm than good.
