"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

While there is no specific “best” method to clear hair out of a drain, several options work well. Using a combination of baking soda and vinegar to dissolve the hair clog is a great and easy way to help clear the drain. Drain snakes are also effective for more severe clog buildups. 

The cost to unclog a drain varies based on the location and severity of the clog. For simple clogs within your home, such as in a sink, toilet, or shower, hiring a plumber typically costs between $110 and $350, with an average of around $200. Snaking a toilet or sink usually costs between $110 and $275, while a bathtub or shower clog costs about $225.

For a more serious clog in the main sewer line, the cost is higher. Clearing a main line clog generally costs between $200 and $600, with an average of about $380. However, prices can range from as low as $100 for snaking a minor clog to over $1,600, particularly if advanced methods like video inspection and hydrojetting are needed for a large or hard-to-reach blockage. Some severe main line clogs can cost upwards of $1,000 to clear depending on factors like the cause of the clog, its distance from an accessible cleanout, and whether the pipe is located beneath an occupied space (e.g., in an apartment building). You may be able to save money on minor clogs by using a drain snake or bladder yourself.

To unclog a plumbing vent, you first need to locate it. Look at your home's roofline. The plumbing vent will be a vertical pipe sticking straight up from the roof. Since this pipe runs all the way to the main drain underneath your house, you should also be able to find it in the attic.

The best way to unclog a bathtub drain is to pour a pot of boiled water down the drain, being careful not to splash yourself. However, take precautions, as boiling water can damage PVC pipes and joints. Follow up with ½ cup of baking soda and ½ cup of vinegar. Cover the drain with a small sink plunger and let it sit for 15 minutes. Pour boiling water down the drain again and replace the drain stopper.

A saturated leach field can result from various underlying issues, so it's best to call a professional septic company to diagnose and treat the problem. Depending on the cause of the saturation, potential fixes include pumping out a full septic tank, adding more bacteria to the tank, or regrading the soil to fix low spots. It may also be necessary to reroute rainwater and runoff away from the leach field using gutters, downspouts, and extenders. Once the primary issue is resolved, planting specific types of vegetation over the area can help absorb excess water. In more severe cases, you might need to install a larger septic tank or replace the leach field entirely.
