"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."

Backing up? Got roots? Blast those roots out with a Hydro Jetter! We use a wart hog nozzle that combines controlled rotation with a unique 8 jet cutting configuration optimized for removing roots. It’s better with a jetter! Call us! We got this! ??

"Before we could connect a new clothes dryer, we needed to replace our old spring-loaded gas valve with updated shut-off valve. Also, needed new flex aluminum vent, rigid under house. Alvin at All Season responded quickly. He and his co-worker came out, checked work to be done, and got right on it! Alvin also recommended that we change out old drain stand pipe to 2" for the new clothes washer. So we had him do that, too. We asked Alvin to check our water heater settings. Then he noticed we needed flex tubes and water installed valve replaced, which should have been done when this water heater was installed. So Alvin took care of that for us. Alvin is very nice, professional and patient; a pleasure to work with."

"I had a great experience with a drain cleaning service at my home in Los Alamitos. Our main line was backing up, and they were able to get someone out the same day. Our technician Brandon was professional, knowledgeable, and took the time to explain what was causing the blockage and how he was going to fix it. He thoroughly cleaned the drain and made sure everything was flowing perfectly before leaving. You can tell he really cares about doing the job right. I appreciate the honest service, fair pricing, and quick response. I would definitely recommend Brandon to anyone in Los Alamitos who needs reliable drain cleaning service!"

"I had a major drain blockage in my bathroom that was causing some serious issues, so I called so-cal 1 pluming & rooter based on a friends recommendation. From the moment they arrived, I knew I was in good hands. The technician was incredibly professional and took the time to explain exactly what was causing the blockage and how they would resolve it. They used advanced equipment to clear the drain quickly and efficiently, and I was amazed at how thorough they were. They did not just clear the blockage they also performed a full inspection of my plumbing to make sure everything was in good condition. The whole process was stress-free, and I appreciated how they cleaned up afterward, leaving no mess behind. What really stood out to me was their honesty and transparency throughout the entire process. The pricing was reasonable, and there were no surprise charges. I also received helpful maintenance tips to avoid future clogs, which I thought was a nice touch. Recommend them highly."

"I had a great experience with The Sewer Boyz when they came out to locate and repair my sewer line. Jonathan made the whole process smooth and reassuring from start to finish. He took the time to explain how he would locate the line, clearly identified the problem, and walked me through the repair options without any pressure. His knowledge and professionalism immediately gave me confidence. The repair was done efficiently and with great attention to detail, and he made sure everything was working perfectly before leaving. What really stood out was how respectful and personable Jonathan was. He treated my home with care, cleaned up thoroughly, and made sure I understood everything that was done. I truly appreciate his honesty and quality of work. Highly recommend this company. Definitely a 5-star experience!"

French Drains FAQs, answered by experts

Chemical drain cleaners can work to clear clogs in pipes, but their use should be approached with caution. These harsh chemicals can damage pipes over time, and they can also harm the environment. Use them sparingly and consider alternative methods such as using a plunger or a drain snake. If you have concerns about a persistent clog, it's best to consult a professional who can safely and effectively address the issue without causing further damage to your plumbing system.

No, you should not see water in a sewer cleanout. If you do, it could indicate that you have a block or leak in your main sewer line—which can cause sewage to back up inside your home and potentially flood your yard. Your best bet is to call a local sewer cleaner if you notice any water or sewage around your cleanout.

It’s sometimes difficult to distinguish a clog from a frozen drainpipe since ice technically causes a clog. If the temperature doesn’t tip you off, there are a few additional signs that your pipe is frozen. Look for condensation and frost around the pipes. Ice in pipes can cause a banging or clanking noise as opposed to a clog from a softer material.

Grease buildup, tree roots, and foreign objects often cause blockages. Regular maintenance prevents major issues.

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.
