"Perfect! I called Western Rooter the AM my disposal went out. They were at the house the same day, at the time they stated they would arrive. The work was done efficiently and professionally and completed within an hour. I have called on Western Rooter for many years for various plumbing needs (clogged drains, replace water-heater, replace main water line, etc.) and have always had great, timely service at reasonable $$$."

"We had old clogged pipes in two different areas of the house so we called Tony’s for help. Tony came out the day I called to give a consultation. A couple of days later he sent a quote for the repairs and by the end of the week he had a crew at the my house to do the repairs. Kevin and Juan were punctual, hard working and super nice guys! Before work got started they tried their best to protect our home from the dust and dirt. I was really grateful for their efforts. They also kept us updated through out the whole process. At one point during the day there was a need to snake one of the pipes and Paul came out to help. I’ve worked with Paul before when our water heater went out so I knew we were in good hands! At the end of the day Kevin and Juan did an incredible job of cleaning! Drains are working properly again and we are thankful to have found a plumbing company with so many great workers! The price we paid was close to the quote. Once the walls were open they found some complications that couldn’t have been foreseen. We are appreciative that Kevin and Juan figured out a way to fix the problem while trying to save us money. You won’t regret hiring Tony’s Plumbing!"

"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!"

"They really are 'good guys'! Not only did they fix the problem (our sump pump stopped working), but they were very honest with us about it. They could have tried to sell us a new sump pump, but they took the old one out (which really isn't very old), and they repaired it right there on the spot. They also made some changes in the pipe that it was connected to (shortened and repositioned it) so the problem wouldn't happen again. We've actually used them again since this initial experience and they were just as great. They're reasonably priced and I highly recommend them."

Drain Cleaning FAQs, answered by experts

Yes, frozen pipes can prevent a toilet from working correctly. If the pipes are frozen, water cannot flow, which means your toilet tank won't be able to refill after a flush. This will prevent the toilet from flushing again. Depending on which lines are frozen, the ice can also block the drain pipe, preventing water from flushing away.

As a temporary workaround, you can manually add water to the tank for each flush. To clear a frozen drain pipe, you can try filling the toilet bowl or tank with warm water and flushing to help thaw the ice. However, the best long-term solution is to unfreeze the pipes to get your toilet back in working order.

While technically possible, it is unlikely that a clogged toilet will fix itself. Clogs caused by water-soluble materials like toilet paper or human waste may eventually break down in the water, allowing flow to resume. However, this can take time, and any clogs from solid objects require manual removal. In most scenarios, especially if you don't have another bathroom, it is best to fix the clog yourself or call a plumber.

You should hire a sewer service professional to unclog a main sewer line with tree roots. Tree roots can grow into the main sewer line, and this problem requires a specialized hydro jet, or rooter, that is powerful enough to clear the roots. The tree can also damage the main sewer line, and a professional will need to make repairs or replace the damaged sections. Sewer line replacement costs about $60 to $250 per linear foot.

Anything from debris, rust, ice, and even poor installation can cause clogs in your plumbing vents. Some signs of a clog include slow drains, gurgling sounds in drains and toilets, and bad odors. The bad odors are the most concerning, as these can include methane and hydrogen sulfide. Contact a plumber to come take a look if you notice any of these signs.

Using less toilet paper is the easiest way to prevent future clogs. Also, avoid flushing sanitary products, thick paper towels, or hair down the toilet. If you’ve been using a brick in the tank to reduce the water used to flush the toilet, take it out immediately. Bricks will eventually fall apart and clog your toilet drain. Keeping your toilet lid closed also helps avoid future clogs.
