"Al Cyr the owner is as professional as it gets! He worked very hard at unclogging my drain that had a root mass blockage from a ficus tree. Unfortunately, he could not cut the root because it was too large and suggested a company who has the equipment to cut through the root mass and view it through a camera. Al was honest, fair and knowledgeable and I would definitely hire him again as well as recommend him."

"We had been dealing with our shower slowly draining for about a week. After reading their reviews, we called California Plumbing. They used a hydro jetting machine to clear out years of buildup and our shower is draining much quicker. So satisfying!"

"2 months ago We needed to replace the pipes in our house after having serveral leaks. Pablo Solis and his team were friendly, prompt & did a great job! They kept me updated as they completed the project and made recommendations when needed. They were kind enough to fix a small toilet issue we were having even though it was not part of the project we hired them for. I recommend them 100% ð ð ¼ The pricing was very competitive. We would definitely use them again."

"The plumber showed up on time and actually called when he was about 30 minutes away. He had the necessary repair part on his van and was able to complete the job in approx. 90 minutes. Nice attitude and cleaned up the area before he departed the bathroom. I can't say enough about Vista Plumbing. This is the 2nd time I have used their services and it is always perfect. Maybe a little pricey but to me it is worth knowing the job will be done right the 1st time."

Drain Cleaning FAQs, answered by experts

French drains may fail when they become clogged with soil granules that slip through the pores of the landscaping fabric and through the holes in the pipe. 

Over time, this debris can build up inside the pipe and prevent water flow. To prevent this failure from happening, regularly flush out your French drain and keep debris away from the inlet grate.

The drain pump will naturally make a standard operational and draining sound several times throughout your dishwasher cycle. If you hear abnormally loud sounds like scraping, grinding, or clicking, you may have food debris or a piece of glass stuck in your drain filter. Avoid dishwasher repair by always scraping food off your dishes and loading the racks correctly.

To get rid of a sewer smell in your crawl space, you’ll have to find the source of the problem. If it has to do with your sewer lines, then repairing the line will help. You may need to make other repairs, like fixing your sump pump or encapsulating your crawl space to reduce moisture. After you make the repair, depending on the issue, you may still need to clean out your crawl space to get rid of the stink.

Yes, you can use hydrogen peroxide to unclog a drain. Instead of using a baking soda and vinegar solution, you can use baking soda with hydrogen peroxide. The process to unclog a drain is the same as with vinegar, but use 1 cup of hydrogen peroxide instead.

Coke and other sodas do clean a clogged drain, so this is one of those urban myths that has some truth behind it. Coke and similar sodas are caustic and will provide some cleaning power to your drains. However, the power of soda pales in comparison to dedicated cleaners or even baking soda.
