"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! ??

"David came out after hours to clear a badly clogged drain for us, and we couldn?t be more grateful. We had water backing up and were really stressed, but he arrived quickly, was very professional, and explained everything clearly. He used hydro jetting to thoroughly clean the line, and you could immediately tell the difference ? the drain has been flowing perfectly ever since. What really stood out was his attitude and work ethic. Even though it was late, he took his time to do the job right and made sure everything was clean before leaving. Fair pricing, honest service, and top-notch work. Highly recommend David for any drain or sewer issues!"

"⭐️⭐️⭐️⭐️⭐️ Outstanding Service, Integrity, and Communication We had SoCal 1 Plumbing & Rooter handle a job on our exterior drain pipes, and the experience exceeded our expectations from start to finish. Not only was the work itself done extremely well, but what truly set this company apart was their professionalism, transparency, and genuine care for us as homeowners. Their executive manager, Shane, was personally on site to diagnose the issue, provide a in depth explanation, organize his crew, and ensure everything was handled correctly. He even returned to confirm that the job was completed properly. Having direct access to a manager who was knowledgeable, responsive, and willing to answer questions made a stressful situation feel completely manageable. I could call Shane at any point to bounce questions off of him, and every recommendation was explained thoroughly and honestly. They took the time to help us understand the severity of the problem, and exactly whats needed to fix"

French Drains FAQs, answered by experts

You can try several easy methods to unclog a drain, one of the easiest and most effective of which is to use a mixture of baking soda and vinegar. This will help dislodge and dissolve the clog to move it down the drain pipes. Pour 1/2 cup baking soda into the drain, followed by 1/2 cup of white vinegar. Dump several cups of boiling water (or hot water if you have PVC pipes) into the drain and let sit for up to one hour. Run hot water to clear the drain.

If your washing machine drain is clogged, that isn’t a good sign. Unlike toilet drains or kitchen sink drains, there isn’t matter that is easily broken up with a plumbing snake, and more care is required. If you’re in an old house or have mineral-rich water, there could be a buildup inside the pipe. Either way, if the blockage isn’t obvious and doesn’t dislodge with a snake, you need to call a pro—otherwise, you risk damaging integral plumbing.

There are a few reasons your snake won’t go down the floor drain. One common reason is a large obstruction in the drain that is causing a blockage. You can remove any debris you see in the drain before trying to snake it. In addition, the snake might not be long enough to reach the clog, or it might be the wrong diameter. 

A liquid drain cleaner can sometimes make a clog worse over time if you use it improperly or too much. The chemicals in drain cleaners can corrode and damage pipes, causing cracks and leaks that may cause further blockages. If the clog is more than the liquid drain cleaner can handle, the cleaner will simply add chemicals to a bigger overall problem.

No. You should dispose of all oil-based finishing products through a local hazardous waste program. Not only can oil-based finishes be hazardous for the environment if disposed of in the sink, but they can cause clogs in your pipes and stop up your drains. Most municipal garbage or waste disposal companies have a specific location or pick-up schedule for hazardous materials, so that’s your best bet to get rid of excess finishing products.
