"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"

"Our landscaping in Menlo Park needed a complete refresh. The team replaced thirsty plants with drought-tolerant options that still provide plenty of color and curb appeal. We're using much less water without sacrificing appearance."

Septic Tanks FAQs, answered by experts

Perc rates vary dramatically, and a good perc rate could be anything from 5 minutes per inch of drainage to 60 minutes per inch. The lower the number, the faster your system will drain and the more effective it will be. A 60-minute-per-inch drain rate is the highest number considered to be good, or even allowable, draining.

Expect to take at least a day to drill your own well by hand. For a 500-foot well, this could take even longer, depending on the makeup of the soil and the terrain you are drilling through. Other factors include your physical strength and overall fitness level and the weather conditions you’re working in.

The average three to four-bedroom home typically uses a well pump rated for 8 to 12 gallons per minute (GPM). To find the most accurate size for your specific needs, a common rule of thumb is to count the number of water fixtures and appliances in your home and aim for that number in GPM. This calculation allows for about one gallon of water per minute per fixture. Because estimating the correct size can be challenging, it's best to have a professional technician make the final determination. A professional can ensure your pump provides sufficient water for your home, especially during peak usage hours.

A septic tank riser should extend to just above the ground level or slightly above it. The exact height can vary depending on local regulations and personal preferences, but a common guideline is to have the riser's top flush with or no more than a few inches above the surrounding ground. This height allows for easy access to the septic tank without creating a tripping hazard or obstructing mowing and landscaping activities. It's essential to ensure that the riser lid is easily visible and accessible for regular maintenance and inspection while being mindful of safety and aesthetics.

Septic tank lids may or may not be buried in a yard. Most lids are buried at least 4 inches deep unless you have an aerobic septic system. Aerobic septic systems need frequent cleanings, about every four months, so it’s best to leave these lids aboveground for easier access. For buried lids, homeowners can use risers that make it easier to locate and access a buried septic tank lid.
