"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."

"I had 2 project with this vendor. Jose & Alex both came to the rescue. 1st was a quote and later water heater install. Then had a old cast iron drain clog that required replacement. They were professional and skilled. I am happy with the service and their fair pricing. Don’t bother shopping around and waste time give them a call directly."

"The plumber spent a lot of time just trying to figure out the source of the hidden leak. He had a lot of patience. The quality of work was good as was the price. I would definitely hire them again."

"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."

French Drains FAQs, answered by experts

There are many things that could cause your basement floor drain to back up. One significant cause of a drainage backup is flushing non-flushable items, such as wipes, paper towels, and facial tissue. Other causes of a backed-up basement floor drain include tree roots impeding the drain pipe or an accumulation of hair, oil, and grease. 

Sometimes, the drain is just too clogged—thanks, stubborn hair and soap scum. In this case, you’ll need a more powerful drain cleaner than you can DIY safely at home. But this doesn’t mean you have to choose a traditional drain cleaner. 

You can find biodegradable drain cleaners at your local home improvement store or online for those drains that need a little more oomph. 

While on the hunt for a formidable drain cleaner, the best options are non-chemical clog solutions that combine enzymes and bacteria.

DIY plunging or drain cleaning chemicals may help minor clogs, but professional hydro jetting ensures long-term solutions.

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.

No, you should avoid using liquid drain cleaners. These chemicals, often packed with sulfuric or hydrochloric acid, can wreak havoc on your pipes, causing erosion and potential leaks. They’re also dangerous to your health. If you’re dealing with a stubborn clog, manual removal or a professional plumber is your best bet. Chemical drain cleaners can often make things worse, especially if the clog stays put and the chemicals linger in your pipes.
