"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!"

"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"

"Excellent service. Ray called ahead of appointment to confirm model requirements. He found that a leak was starting. I trust his judgment. I have used Vista plumbing for 20 years for toilet replacement to water heaters and I am always satisfied."

"I called several popular plumbing companies to replace an old dripping shower/tub faucet in the guest bath. All wanted to use their fixture and cut the shower tile to fit the new fixture, so I gave up. After a year or so, I joined Angie’s list and found Top Notch plumbing. Gordon had some fixture recommendations, but allowed me to purchase my own fixture that was compatible with my current installation. The overall install took about 3 hours. Gordon took care during the work to not damage any existing tile or carpet. He knows his craft and performed a very clean and professional install. Overall, I highly recommend Top Notch plumbing and will be saying goodbye to the popular TV advertising plumbers. Thanks Gordon!"

"Overall, it was excellent. Jerry (the owner) came out and was very straight forward as to what needs to be done. Price (compared to 6 other companies) could not be beat. Work was scheduled reasonably quickly and went smoothly. Problems were discovered after installation and when made aware, Jerry and his crew made sincere efforts to set it right – and were able to solve the issues in couple of visits. All of the crew and management went out of their way to ensure that we were satisfied with the work and overall result. Would definitely consider Liberty Plumbing for future work."

"Great job. Anthony did a complete review of the house and the current venting and recommended the proper size for the AC. The installers and electricians came 3 days later, did additional wiring and piping and installed the entire system in 5 hours."

Drain Pipe Installation FAQs, answered by experts

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.

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.

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.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

That pungent rotten egg smell coming from your drain is likely the buildup of biofilm—hair, skin, and soap scum that turns into a black sticky mess. In this case, pouring down near-boiling water, baking soda, and white vinegar will remove the smell. Keep in mind that a rotten egg smell is occasionally a sign of larger sewage line clogs and other related issues.
