"Wilmar arrived exactly on time and took care in taking his shoes off and ensuring all of the work area was nice and clean. He fixed a leaking bathtub faucet and after fixing the faucet he re-caulked the shower head fixture and downspout no charge. And, as he was cleaning up and washing his hands in the bathroom sink, he noticed it was draining slow, and the drain had a loose nut. I told him, he did not have to repair it because I knew he had to go to another job but he insisted on doing it. He went back out to his truck, got his tools, took off the p-trap and cleaned it all out at no-charge. Honestly, who would do that? Great guy and I highly recommend."

"Jess and his crew did a great job recently repiping my house, both the water supply and drain lines. Jess is easy to work with and very responsive. His price was very reasonable. He came back promptly to fix some very minor issues I found (tiny leaks from the kitchen sink drain and from one of the outside faucets). Everything is fine now. The sprinklers in my backyard work better now because they're getting more pressure than they got from the very old galvanized pipes that were replaced. I'm happy to recommend him."

"The folks @ Mike Counsil have done work for us in the past, including the heater installation and unclogging/cleaning a backed up drain. Any time we've had work done by them, they are always right on time and very professional. They get the job done and clean up after they're finished to ensure there's no clean up for the customer. I highly recommend them for all of your plumbing needs."

"The actual job was to essentially replace the entire sewer system from fixtures to the town hookup, along with replacing toilets. Daniel and Jaime were awesome!. We contacted them based on very positive feedback from a neighbor who had them perform some work for her. They did a very thorough up front inspection (with pictures) and explained the current state of the system and provided a variety of options to address the issues they found. All of their work was top notch (and included before and after pictures). They always kept us informed of what was happening when - and were always on time. They thoroughly explained what they were doing and why. The work was performed in a minimally disruptive way - we almost always had some level of service available (a working bathroom, etc). They started the job by laying down some impressive floor coverings to protect the house, and at the end of each day they cleaned things up. When the project was completed they restored the front yard very nicely (they left very few signs that anything was done - which was impressive considering the amount of work done). They were very professional, friendly and easy to work with. I am a completely satisfied customer and would recommend Swags without reservation."

French Drains questions, answered by experts

An active cleaning agent and a drain snake is the best way to clean a main sewer line. You can purchase a regular or enzyme drain cleaner or make a DIY drain cleaner with baking soda. Use your chosen solution at least once a month or as needed to keep your sewer line clear. 

A clogged air gap can cause a dishwasher not to drain. There are, however, other potential issues that can lead to improper drainage. For example, if you have attached the air gap to a garbage disposal and forgotten to remove the knockout plug, wastewater may backflow into the dishwasher. Check that the air gap is installed properly, and then look for clogs in the air gap and dishwasher filters. 

There are several common signs that your main sewer line may be clogged. Key indicators include multiple fixtures in your home draining slowly, gurgling sounds coming from drains or toilets, and water backing up into showers, sinks, or toilets. You might also notice water backing up from the plumbing system's drain cleanout, water in your basement drain, or unexplained wet patches on your lawn. Foul odors, such as the smell of raw sewage or rotten eggs, are another common symptom. The most reliable way to confirm a main sewer line clog is to hire a professional plumber to perform a camera inspection.

Inspect regularly for clogs, clean drain lines, and ensure grading directs water away from the foundation.

DIY is not recommended due to safety risks and specialized equipment requirements. Hire professionals for effective clearing.
