"I was totally happy with their work. They went beyond my expectations. They even checked the sewer line to see if it was in good shape. That also went under the house to replace a small section of galvanized drain pipe with a plastic pipe.Our kitchen drain is draining great. It turns out that the vent in the drain was plugged. We would recommend them to anyone. Joanne Tomlinson"

"Anton and his son Marco came to our home and replaced our waterline and our neighbors waterline. They also de-scaled and flushed our tankless water heater and rebuilt our toilet tanks. The communication was fantastic, the knowledge was so appreciated, and the work was efficient and thorough. It was a joy to have them working in our home. I would highly recommend them to anyone in the future."

"Anthony was extremely knowledgeable and explained everything so clearly. He suggested I replace the narrow galvanized drain pipe or the clog would happen again. Which it has several times. I agreed on the replacement and he went ahead and snaked the drain so I could use the sink and washer until he could come back and do the job. I will definitely call him again."

"David was very professional and skilled. On a Sunday, he responded quickly to my urgent request (water was backing up into my bathtubs due to an underground pipe breakage). He was able to identify the source of the problem (which was not straightforward), cleaned and fixed a broken exterior underground drain (with Nu Drain). He even identified and fixed another displaced drain connection, and installed a cleanout at the exterior of home. He had a very positive attitude (even in the cold rain) and stayed until it was done (while working in the dark). He was very good at explaining the situation and the work that needed to be done. He seems to have state-of-the-art equipment. He went above and beyond my expectations. I will highly recommend him to my friends and family. Would definitely hire this service again."

"They saved me $$$ thousands of dollars. These people are great. I had a clogged drain so I call plumber. The plumber that fixed my drain said I needed a new sewer main. So I got five different bids. Axiom PDX gave me bid which was less than the others but was honest enough to tell me a new sewer line was not necessary."

"I had a clogged drain that no amount of plunging could get rid of. I called several companies. I initially went with Mr Rooter because they were the only ones that could make it out that same day. Glad I did. The technician was very pleasant and he took his time to explain all the steps he was doing and let me watch as he put a camera down the drain and showed me on the screen where the clog was and all the build-up in the pipes. He then brought in a high pressure washer and I watched on the screen as he cleaned the pipes all the way down to where it joined up with the main sewer line. I initally thought the estimate was a little high, but not after watching all that they (his supervisor also showed up after an hour to help out) did."

French Drains FAQs, answered by experts

When you put baking soda and vinegar down the drain, they chemically react and help break down clogs. It’s not going to work for every type of clog, however. For example, it’s not the best way to get rid of grease buildup. For grease, you should try boiling water and white vinegar instead.

You may have a clogged gutter. Downspouts can also clog if your gutter collects too much debris. Hire a professional gutter cleaner, and if you still have problems, install a gutter guard (which prevents debris from entering your gutter system) and a downspout extension (which helps drain water further away from your foundation, so it doesn't pool near your house). Follow these tips to keep your gutter downspouts clean.

To prevent drain clogs, perform regular maintenance and cleaning. Avoid disposing of substances like grease or coffee grounds down the sink. Additionally, installing and routinely using drain strainers can help catch debris and prevent blockages from forming.

Liquid drain cleaners are harsh chemicals that can erode your pipes. To treat a slow drain or for preventative maintenance, pour hot water down the drain to break up gunk and help move it along. Make sure the water isn’t boiling hot (keep it under 140 degrees Fahrenheit) if you have plastic pipes. However, you’ll need to pull the clog out for bigger backups. 

In some cases, operating a snake can damage your drain and pipes. This depends on the overall condition of your pipes and how gently you operate the auger. For instance, older galvanized pipes covered in zinc are susceptible to scratches when using a drain snake. Additionally, it’s common for newbies to apply too much force when extending the snake, leading to scratches and related damage. You can also crack the porcelain with an electric auger if you’re snaking a toilet drain. If you’re using a manual snake or auger, the risk is minimal.
