First Class Riverside plumber serving all of Riverside County and the surrounding area. Receive a free inspection and quote, same day service, and family-friendly service.

"After the gas company refused to turn on our gas due to leak, I searched for gas leak service through Angies. First Class plumbing called and I asked them to perform a test to find out the source of the leak. I agreed to pay them $360 for this service which would be applied to the repair cost should I have decided to choose them for repair. The did a pressure test, confirmed the leak. However, they guessed where the leak was. They said the leak is somewhere underground between the gas meter and where the gas pipe enters teh house (~28 feet). They told me replacing that under-concrete pipe would cost me $9000 and if I do the post repair concrete patch, it would cost $7,000. I asked them to change the whole gas pipe in the yard (b/c it was old), they said $15,000 if I do the post-repair concrete path myself. Based on their statement I signed a contract for $15,000 to replace the whole gas piping in the backyard. Before they were going to show up next day, I asked them to delay the start of the work until Monday (3 days delay). I asked another gas company to do the diagnosis. The leak wasn't in the part of the gas pipe that was going from meter to the place the pipe enters the house. He isolated the segment that was causing the leak, then the leak was gone. I can send you the diagnosis from both companies. I would like First Class piping to pay me my $360 b/c their diagnosis was erroneous. Not only would I have paid the $7000 without having fixed the leak, but I would have damaged the concrete in the yard as well. In their diagnosis, First Class is saying there are Ts under the ground etc. which is absolutely to the case. He would have seen there were no Ts had he used his borescope camera as I asked him to do. I am asking them to pay me back my $360 which is the least they should do."

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.
