"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

Yes, sewage smells can originate from a floor drain. If the P-Trap in the floor drain dries out or if there's a clog or other issue in the plumbing system, sewer gasses can escape through the drain, causing nasty odors. Regularly pouring water into the drain helps maintain the water seal and prevent those smells, but if the smell persists, you should have a plumbing professional inspect the drain for potential problems.

The drain pump will naturally make a standard operational and draining sound several times throughout your dishwasher cycle. If you hear abnormally loud sounds like scraping, grinding, or clicking, you may have food debris or a piece of glass stuck in your drain filter. Avoid dishwasher repair by always scraping food off your dishes and loading the racks correctly.

If your drain doesn’t have metal crosshairs or crossbars, you should use a tub drain extractor. These tools create a grip on the drain so you can turn it using a 1/2-inch ratchet drive, drain key, or wrench. Your drain may not have crosshairs if it's old and broken.

If your dishwasher keeps filling with water at the bottom but doesn’t fill into the sink, the issue is likely due to a blockage within the dishwasher or drain. Regularly clean your dishwasher filter basket to ensure it’s not clogged with food, and run a vinegar rinse periodically if you have hard water to remove limescale buildup.

Clogs in a sprinkler valve can be caused by various factors, including debris in the water supply, sediment buildup inside the valve, or damage to the diaphragm. Debris and sediment can accumulate over time, obstructing the valve's passages and impeding water flow. Damaged diaphragms may develop tears or holes, leading to blockages and affecting the valve's ability to open or close properly. Regular maintenance and cleaning can help prevent and address these issues, ensuring your sprinkler valve operates smoothly.
