"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."

"I called Ca-Tech on a Saturday morning to check my water heater, and I was impressed that they were able to come later that morning. Albert arrived when he said he would and was very personable and very professional. He gave me a quote for a repair and also to replace my water heater. I choose to replace the water heater. When Albert returned later that week, he came on time and was very professional with the way he did the work. I liked that he kept me informed. I will definitely call Cal-Tech Pluming again."

"Outstanding Service from John at Drain City Plumbing Services I cannot say enough great things about my experience with John from Drain City Plumbing Services. He came out to unclog my shower drain, and from start to finish, his professionalism truly stood out. John arrived exactly when he said he would, was courteous and respectful, and immediately put me at ease. He took the time to thoroughly explain what was causing the problem, what steps he was taking to resolve it, and how I could help prevent the issue from happening again in the future. I really appreciated that he didn’t just fix the problem—he educated me along the way. His work was exceptionally clean and neat. He treated my home with care, cleaned up after himself, and made sure everything was working perfectly before he left. It’s refreshing to find someone who takes such pride in their work and genuinely cares about providing excellent customer service. I would absolutely use Drain City Plumbing Services again!"

"David came out after hours to clear a badly clogged drain for us, and we couldn?t be more grateful. We had water backing up and were really stressed, but he arrived quickly, was very professional, and explained everything clearly. He used hydro jetting to thoroughly clean the line, and you could immediately tell the difference ? the drain has been flowing perfectly ever since. What really stood out was his attitude and work ethic. Even though it was late, he took his time to do the job right and made sure everything was clean before leaving. Fair pricing, honest service, and top-notch work. Highly recommend David for any drain or sewer issues!"

French Drains FAQs, answered by experts

Bleach isn’t likely to help unclog a sewer line. Bleach isn’t useful in this situation because it won’t dissolve the grime and debris in the clog. Instead, you want to use ingredients that will have a chemical reaction to clear out the buildup, like vinegar or salt and baking soda.

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.

Unlike regular cleanings, snaking your sewer line should be done as needed. There’s no reason to snake your sewer line if you don’t have any noticeable issues, like slow drainage or plugged drains. You can add it to your regular sewer cleaning checklist as a prevention method (on the same 18- to 22-month schedule), but it’s not always necessary. 

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.

As a general rule of thumb, it’s best to clean your linear drain every two to three months to prevent debris buildup. However, if you notice it draining slowly or an odor from your drainpipes, it’s best to clear the clogged drain and maintain it more often. If you let a clog go for too long, you may have to invest in the price of professional shower drain cleaning, which costs about $225.
