"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."

"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!

"My house is very old so we have been having lots of drain/pipes issues.  With 5 grown kids in the house you can imagine what happens when a bathroom is down.  Thank goodness I found The Drain Guys through YELP! My drains knows no time/day it wants to back up and normally it never happens during business hours.  This company not only came out after hours but came out within the hour and relieved me of my problems fast, quick and it was worth the $99.00 charge.  Ed was very professional (some techs are mad when they have to work OT), friendly, put my mind to ease and even looked at another problem (faucet) without hesitation or charging me to just give me an estimate for the faucet.  I had him come back the next day to fix my faucet and gave FREE inspection underneath my house. First class service with AFFORDABLE prices.  When the office called me to let me know they were with Angie's List I jumped at the change to enroll JUST TO PUT OUT THIS REVIEW!  Great Job Drain Guys!  You have a customer for life. [Member name removed]"

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

Most septic system replacements require several days to complete, not including permitting and preparation time. The process begins with site assessment and testing, followed by excavation, component installation, and final inspection. Weather conditions, property accessibility, and inspection schedules can all affect your project timeline. Your contractor can provide a more specific estimate based on your property's unique characteristics.

Standard homeowners' insurance policies don't cover septic system replacement due to age or normal deterioration. Coverage may apply if damage results from specific covered events, but routine maintenance and eventual replacement are generally considered homeowner responsibilities. Review your policy details or speak with your insurance agent to understand your specific coverage limitations.

Look for multiple indicators such as slow-draining fixtures, unusual gurgling sounds in plumbing, sewage odors inside or outside your home, or wet spots in your yard. Unusually lush grass over the drain field area, frequent backups, or recurring repair needs might signal system failure. Addressing these warning signs promptly can prevent property damage and health hazards.

DIY septic installation is not recommended and may violate local regulations. Professional installation ensures compliance with health codes, proper design for your specific site conditions, and appropriate safety measures. The specialized equipment, technical knowledge, and permitting requirements make this a job best left to licensed professionals who can guarantee the system's safety and effectiveness.

With proper maintenance, including regular pumping, a drain field lasts 20 years. Various factors influence system longevity, including household size, water usage patterns, and soil conditions. Regular professional inspections can help determine when replacement becomes necessary. If your system requires increasingly frequent repairs, replacement might be more economical than continuing to address individual problems.
