Septic Installations For The San Francisco Bay Area

Septic systems separate solid wastes from the water used in your home, then allow the treated water to drain away. Whether you are building a new home or replacing the septic tank in an older one, A-1 Septic Tank Service, Inc. can help you with septic tank treatment, septic tank installation, septic tank inspection, and septic tank maintenance near San Francisco.

Septic Tank Installation

Why Good Installation Matters

Septic tanks aren’t designed to last indefinitely. With regular septic tank pumping and maintenance, your septic tank will last an average of 20-40 years, depending on how you use your plumbing system and the tank’s composition. However, one of the key factors in your septic system’s longevity is its installation. A well-installed tank can be expected to last its full lifespan of decades, while a poorly-installed tank can fail in as little as a few weeks, causing problems on your property and inside your home as well. This is because the soil around your tank, the layout of your septic system and drain lines, and the composition of your drainage field all play an integral role in the performance and health of the system. A septic system that is not properly designed and installed by an experienced septic professional will neither perform its function adequately, nor last as long as you expect, resulting in the need for premature septic tank repairs or replacement or septic tank maintenance.

The Steps Of Septic System Installation

If you need septic tank system installation in San Francisco, there are several steps involved. A septic tank installer can help you through this process to ensure you get the right system for your home installed quickly and properly. Here are some factors to consider:

  • You may need a permit to install a new septic system, depending on your property and the system’s design. This step must be completed before installation can begin.

  • If you have an old septic system, it will need to be removed before the new system can be installed. Additional excavation may be needed to accommodate your new tank and pipes.

  • A hole large enough to house the tank and tracks for the drainage pipes in the drain field must be excavated using construction equipment. Your plumber will take care to preserve as much of your yard and landscaping as possible.

  • Once the site has been prepared, the septic tank and all associated plumbing and drainage pipes are installed. Gravel may be packed around drainpipes to provide stability.

  • When installation is complete, the excavated area is filled in and the entire system is inspected before it is put into use for sewage treatment.
