"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

Air gaps get clogged by a few different means. Over time, food and grime can collect in the air gap, leading to a blockage. Mineral deposits from hard water are a common problem. Mineral buildup creates a film in the air gap and tubing, which can cause flow issues, as well as attract debris. Homeowners with hard water may want to remove mineral deposits regularly to keep the air gap clean and clear.

An active cleaning agent and a drain snake is the best way to clean a main sewer line. You can purchase a regular or enzyme drain cleaner or make a DIY drain cleaner with baking soda. Use your chosen solution at least once a month or as needed to keep your sewer line clear. 

Drain fly problems can go away on their own—but only if the insects find the environment inhospitable. Those with a minor infestation can simply flush their toilets and run their faucets more frequently to flush out the flies and larvae. Others will have to deep clean their drains and set up traps.

In the majority of cases, homeowners insurance will not cover a main sewer line root clog. The reason is that most insurance companies consider tree root damage to sewer lines as common wear and tear, which is also preventable. However, you may be able to buy optional add-on coverage, such as "service line coverage" or "sewer line endorsements," that would protect against root damage to your sewer line.

Yes, chemical drain cleaners contain sulfuric acid and hydrochloric acid, both of which are not only dangerous to your health but also extremely caustic. Drain cleaners will corrode your pipes and could lead to destroyed drain lines, especially if the chemicals interact with the piping for long periods. Unfortunately, this extended interaction is likely if you’re dealing with a clog, as the drain cleaner will have just as much trouble as water does moving through your plumbing system.
