"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."

"The plumber showed up on time and was very pleasant and professional. He completed the job in approximately 1/2 hour which I thought was amazing. He took all packing materials with him and left the counter spotless. He did not try to oversell me any additional items over and above the work I asked to be performed. I would definately use Vista Plumbing in the future."

Drain Cleaning FAQs, answered by experts

Most commercial liquid drain cleaners work in 15 to 30 minutes. Consult the label on the bottle for additional instructions or time suggestions to prevent damage to your drainpipes. Alternative solutions such as baking soda, salt, white vinegar, and/or boiling water can take longer since they are less harsh than liquid drain cleaners.

Some experts estimate that descaling your cast iron pipes can extend their lifetime by upwards of 50 years, although there’s not a lot of research to prove it. But we do know that without proper maintenance, cast iron pipes can quickly rust—leading to more expensive issues like burst pipes or main line clogs.

Chemical drain cleaners can work to clear clogs in pipes, but their use should be approached with caution. These harsh chemicals can damage pipes over time, and they can also harm the environment. Use them sparingly and consider alternative methods such as using a plunger or a drain snake. If you have concerns about a persistent clog, it's best to consult a professional who can safely and effectively address the issue without causing further damage to your plumbing system.

A bit of water in the bowl can help unclog a toilet, especially if you're using a plunger. However, if the bowl is full to the brim, you'll need to strap on gloves and remove some of the wastewater in a cup or container so it doesn't overflow when you try to unblock the pipe. If you're concerned about it filling further, manually close the flapper in the toilet tank or turn off the water supply to the toilet.

You can drain a hot tub very quickly by using a submersible pump rather than the hose-sized drain at the bottom exterior of the tub. A pump can move up to 30 gallons per minute, draining your hot tub in no time. Using the regular drain can take up to two hours.
