"The technician was early, polite, and efficient. The price was fair and the work fixed the problem. He did offer to run a camera down the drain line, but every plumber I've ever hired has done that and he didn't force the issue. An all-around terrific experience."

"Daniel and Andrew helped me rid the roots out of my drains and pump my septic system. They were very professional, courteous and trustworthy. They quoted a price and stuck to it despite there being some difficulties to the project that other plumbers would have charged more for. They left my yard the way they found it and cleaned up after themselves. And they did all this is a very timely matter in our horrid summer heat. They will be my plumber for life!"

"The technicians (Jonathan, Justin, Eddie and Hugo) were so pleasant, knowledgeable and prompt. They came out within hours of our call. They made it so we could use the toilets until they could come out the next day to make the drain repairs and pump our septic tank. We had more problems (not from the first repairs) with our bathroom and they came back out that day to determine what else was wrong and completed the repairs the next day. I would definitely hire them again and would recommend them to anyone needing the services that they provide."

"Tim arrived prompt. Diagnosed the problem with my AC. Provide two recommendations to replace the broken condenser. Also gave additional recommendations to for my AC to keep running effectively during the coming months. Feels nice right now that my AC is working much better. Thanks Tim"

"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."

"I had to call for appointment one week after no contact regarding the form I filled out online for what kind of service I wanted and what times were acceptable. They had to reschedule even after setting the date on the 12th. Continually tried to upsell me to replacement rather than repairs. After interacting with him, I'm not sure labor is included on replacement or even repairs. I bought the 3 year package but had to request a refund."

  I needed a plumber for my Moms house and found Brian and his team by luck.  I will say that they were on time, professional, and did a fantastic job with our clogged line.  Also, the price was right where I thought it would be for having a plumber at my house all day working hard.  This is a first class operation.

  I will recommend them to any one who asks!  Great Job!

FAQs for septic system installation and replacement projects in Riverside, CA

The smallest standard septic system uses a 500-gallon tank, which costs between $875 and $1,150 installed. This size works well for single-occupant dwellings with minimal wastewater production. However, many local regulations specify minimum tank sizes, so check with your building department before committing to this compact option. Some jurisdictions require at least 750 gallons regardless of home size to ensure adequate waste processing capacity.

The installation timeline varies based on site conditions, permit processing, and contractor schedules. The process includes obtaining permits, conducting soil tests, excavation, tank placement, leach field construction, and final connections. Weather conditions, soil challenges, and inspection scheduling can all affect the overall timeline. It's wise to begin planning well in advance of when you need the system operational.

The most economical approach is to install a conventional anaerobic system with a plastic tank. To minimize costs while maintaining legality, obtain multiple quotes from licensed installers, consider scheduling during their slower seasons, and handle basic site preparation yourself. Never skip permits or required testing to save money—illegal installations can result in significant fines and mandatory removal, ultimately costing far more than doing it right initially.

Regular pumping helps prevent system failures and extends operational life. Most small systems require pumping every three to five years, though frequency depends on household size and usage patterns. Pumping services cost between $290 and $530, making this maintenance expense relatively minor compared to potential repair costs ranging from $500 to $2,600 for neglected systems. Establishing a regular maintenance schedule based on your installer's recommendations helps avoid costly emergency services.
