"I did not hire Al, but he called me and we had a good discussion about my issue and he ended up recommending another company that specialized in jetting landscape drains. Nice guy and knowledgeable. I added him to my favorites to call when I have any other plumbing problems."

"Excellent service! We scheduled Plumbing Plus to replace the hot and cold cartridge's in a sink faucet and a tub pop-up drain and overflow gasket. Jared N. quickly assessed the problems. The faucet was so corroded with water deposits that it could not be dismantled to simply replace the hot and cold cartridge's. So Jared replaced the entire faucet with a high quality replacement. After the tub pop-up drain was replaced, Jared checked for leaks by looking in a 'trap door' in the ceiling below the tub that was left after the tub was replaced in an earlier remodel. Jared discovered that the entire tub drain was leaking and need to be replaced, which he did. He also corrected a problem with the drain pipe left from the previous remodel. Although the job was much more complex than expected, Jared was professional, efficient, and extremely cheerful throughout . We highly recommend Jared and Plumbing Plus"

"I’ve had issues with my outdoor drain clogging. Alex helped me schedule an appointment and ensured me they would have the equipment to high power clean my drain. Sure enough the technicians showed up and were able to clear my drains same day. I’m very pleased with their great service!"

Small jobs welcome

"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."

"Your guys CJ & Andrew were awesome! They did such a nice clean looking job! Super professional and very informative. They walked me through setting up the app for the whole house water shut off valve they installed and now I get a reduced rate on my homeowners insurance. They also found that my water pressure reducing valve had failed and replaced that at the same time. Couldn’t be more happy with the job they did."

Drain Cleaning FAQs, answered by experts

A two-way cleanout can help if there’s already a clog, but the best strategy to prevent one is by not rinsing grease, oil, or fat down your drains, not flushing or rinsing coffee grounds or egg shells down your drains, flushing only human waste and toilet paper (so no diapers, period products, bathroom wipes, or paper towels), and using drain guards on all of your drains.

It can take anywhere from half an hour to a few hours to fix a main line clog, depending on the cause and severity of it. The job should not take more than a day to complete. Keep in mind that the main line is not the same as your home’s sewer lines (which connect to the main line and run to your house). Your city is responsible for any clogs or damage to the main line itself.

Yes—your local septic company can clean your septic leach lines with a sewer jetter, a device that pumps high-pressure water through the lines to blast out any clogs and scum buildup. Unless there’s a clog or blockage in the lines, however, you do not need to perform this maintenance regularly. Do not attempt to clean your own leach lines, as you could easily damage them, leading to very costly repairs.

Regardless of the drain cleaner type you choose to use, they all work through chemical reactions that create heat. Thanks to the heat, the clogged hair begins to dissolve until it is able to be flushed away. To avoid clogs in your drain due to hair, use hair catchers and empty them out after every shower.

It is safe to flush small amounts of bleach down the toilet. Don’t flush more than ¼ cup of bleach. Instead, consider diluting it and pouring it down the sink drain.
