"The workman was personable and understood the problem I had been having with the toilet backing up a couple of times during the preceding two weeks. I told him that another plumber had been out and recommended the septic tank be pumped. The work was completed in a reasonable amount of time and the lids were replaced as they had been previously. Everything works fine now."

"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."

"

This was a special order faucet from Delta purchased about 10 years ago.  I did not locate a model number and therefore, I need to replace the faucet.  Haven't had the money to replace it yet so I haven't called them back to do the work.  I may just have a new one installed by Lowe's since that is where I will purchase the new one.  Assume they will have the appropriate tool.
This provider was very prompt and responsive.  The original person couldn't come, so they called and explained and then sent someone else.
However, I was a bit dismayed that the plumber showed up without a tool that would take apart the faucet.  It was special order, but it's a standard Delta that is fairly commong these days.

FAQs for septic system installation and replacement projects in San Diego, 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.
