"Anthony Fankhauser (Owner) is an exceedingly polite individual who provided detailed information on work to be accomplished. Unfortunately, the day my septic tank was being pumped coincided with a number of issues Anthony was experiencing on another job. For that reason, my task was delayed until after 6:00 PM. When Anthony arrived late in the evening to complete the work, he performed camera inspections and explained some minor issues. There was no indication of irritation or frustration due to the issues related to his other task. This was refreshing since I sincerely expected him to vent regarding problems experienced with his other work. I seriously recommend using Anthonyâ s services if you have plumbing issues."

"We had a great experience with GG’s Plumbing at our cabin in Lake Arrowhead. We originally hired them to install a whole-house water shut-off system, and the job was done quickly and professionally. While they were there, the team noticed that our pipes weren’t properly insulated — something that can obviously become a real issue in the mountains during winter. What I appreciated most was their approach: they didn’t pressure us at all. They simply explained the risk, gave us the option to fix it now or later, and let us decide. That kind of honesty goes a long way. We chose to go ahead and have the insulation done, and I’m glad we did. Their team was easy to work with, the communication (mostly through text) was fast and clear, and everything was handled smoothly. Reliable, knowledgeable, and straightforward — I would absolutely recommend GG’s Plumbing."

"They were quick to respond. Wally went over all of the repair options in detail but didn’t try to hard sell me on anything. They completed the repairs within their quoted time, were professional and courteous. I would rehire them in the future."

"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 questions, answered by experts

Yes, a septic tank can get full. If this happens, you might run into issues flushing your toilets or draining your sinks. You may also notice your pipes making gurgling noises or the smell of sewage floating around your house. Other signs of a backed-up septic tank include water pooling or fresh, healthy grass growing above your drain field.

While mound septic systems can provide cost-effective wastewater treatment in many instances, they do come at a significant initial installation cost and require a lot of space on your property for the mound and its replacement field. The installation cost is so high because this is a project that requires an exceptional level of skills and expertise to execute properly.

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.

The main difference between a mound septic system and a conventional one is that the drain field in a mound system is built up into a mound composed of sand and gravel to increase the filtration time the wastewater sees before it is returned to the aquifer. There’s also a significant cost difference, with mound systems typically costing far more than standard septic systems.

Septic tanks naturally have bacteria that break down some of the solid waste in the septic tank. However, sludge buildup is just part of owning a septic system. While liquid wastewater can be filtered and treated through the system, a septic tank company has to pump the septic tank out at least every few years.
