"We used ARS Rescue Rooter on two different occasions during a 1 1/2 week period. They located problems that the city became responsible for and the second time they located and repaired a water pipe leak underneath the slab in one of our bathroom The people they sent, Shai, Kyle and Clint were professional, knowledgeable, clean and quick. Their work was high-quality and I have never seen such complete cleanup. I would highly recommend ARS Rescue Rooter to anyone seeking plumbing and drain work."

"There was leak in my laundry wall..that seems to come and go. I can not figure out where it is coming from. . I called several plumbers to get their opinion and quote. Several plumbers came and gave their opinion and quote. All of them stated that they need to use leak detection methods because they don't know where the leak is, it will be an extra charge once I agree to hire them. All the plumber gave me a quote based on what I told them. they but did not really do anything before hand . Luckilly Andrew from Service Flow came and I told him the issue and he took his time to diagnose where the leak could be coming from, he even performed an initial moisture detection in thevwhole house and other techniques to find out where the leak is..he really took his time to diagnose the issue and found the issue without an initial charge. He gave me a very good quote. I hired Service Flow because of the care and concern that Andrew showed, great customer service and very affordable."

"Found the main water line to the house broken and spraying water at 8:00 am.  Water was shut off by Water District folks by 9:00.  Joined Angie's List at 9:30.  O'Brien's Plumbing sent Jonathan and R.J. over by 10:30 and they had the break repaired, an inline shut-off valve installed and the water turned back on in under two hours. They even custom fitted a cover for the valve to protect it in the future.  They had the area cleaned up and were out of here quickly and professionally.  Great job.  Although it was pricey it was probably worth it.

French Drains FAQs, answered by experts

You can unclog a double kitchen sink by plunging the side with the garbage disposal. Cover the drain hole on the other side first to avoid creating a mess. Plunge up and down until the water starts to drain. You can also pour in baking soda and vinegar to try and dissolve a clog. 

To clean gunk out of a sink drain, pour in a half cup of baking soda, then 1 cup of white vinegar. The two will react chemically; let them fizz for 15 minutes, then rinse with boiling water. Repeat these steps if necessary for particularly dirty sink drains, and consider a drain snake if there are clogs.

Regardless of the drain cleaner type you choose to use, they all work through chemical reactions that create heat. Thanks to the heat, the clogged hair begins to dissolve until it is able to be flushed away. To avoid clogs in your drain due to hair, use hair catchers and empty them out after every shower.

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.

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.
