"Nothing but good stuff from this company. Adrian (owners' son) is very knowledgeable and professional. I got quotes from two other plumbers for my kitchen drainage pipe massive leak. They both wanted to open-up the floor, and one of them wanted to also break-open the walkway, due to the extremely narrow crawl space. Adrian was the only one of the three that actually took a look under the house and determined that his men could dig under the footing to get to the problem. They arrived at the time scheduled, and left 2 hours later when the job done. And when I say done, I mean the area completely cleaned-up including picking-up the old pipes. They also had to cut into the stucco to get to the vent pipe. It looks like a surgeon did it. The stucco repairman is going to have an easy repair as a result. Trust me, if you're tired of dealing with plumbers that don't care about doing a good job, you have to hire Adrian at AD3 Plumbing for any plumbing issue you have. Adolfo Perez"

Customers say: True professional

"Leo was very helpful and quick to respond. We’re happy with how our 2 bathrooms turned out. Project was completed within the time promised. Our only complaint is that the workers did not clean up very well. But overall, we’re satisfied and we’ll use them again."

Septic Tanks questions, answered by experts

The best solar-panel mounting system will depend on your property layout, but you’ll typically want to try for south-facing panels to get the most sun. Roof mounting and wall mounting are both popular, but if your well setup is far away from buildings and other structures you can also set up a freestanding aluminum frame to mount your panels.

Since vinegar is a weak acid with a pH of two to three, it’s generally safe for septic systems. It won’t eat away at the good bacteria in your septic tank and can help break down the sludge, which is its bottom layer. However, like with everything in life, moderation is key.

Because well water is not artificially filtered or pre-treated, it may contain contaminants. As a result, it’s possible for well water to damage pipes based on what is in the water. Well water can be corrosive, slowly rusting and dissolving pipes, fixtures, and fittings. The corrosion can affect the taste and quality of the drinking water that comes out of the taps in your home. 

Yes, septic tank companies must be licensed in most states and municipalities to perform services like installation, alteration, repair, and pumping. Since laws vary by location, it's crucial to check local requirements.

Hiring an unlicensed professional can lead to poor work, code violations, and significant fines. Always verify that your chosen company is properly licensed and fully insured to avoid liability. You can use tools like Angi’s contractor licensing search to check a pro's credentials.

It's also helpful to understand the difference between licensing and certification. A license is a legal requirement to operate, while certifications are voluntary. Credentials like the “Angi Approved” badge indicate that a business meets extra standards, such as passing a background check and maintaining a high rating.

Yes, shower water goes into the septic tank. Shower water is a type of greywater, and in fact, all water used in a home with a septic system—including water from sinks, toilets, the dishwasher, and the washing machine—drains into the tank. When shower water enters the tank, debris like soap and hair travels with it. The solid debris sinks to the bottom to become sludge, while soap residue joins the scum layer at the top. The remaining water is treated in the tank before moving to the drain field for further treatment and dispersal. It is important to avoid putting oil or harsh chemicals down any drain, as they can cause clogs or disrupt the beneficial bacteria required for proper wastewater management in the septic system.
