Thank God Reliable Excavation was so professional, customer oriented, and did amazing work."

Septic Tank Repair questions, answered by experts

Most septic systems last for between 20 and 30 years, but the life span depends on the tank material, how often you carry out maintenance, and how diligent you are about maintaining septic tank health. Steel tanks last for 15 to 20 years, concrete tanks last for 20 to 40 years, and fiberglass and plastic tanks last for 30 to 40 years. You’ll more often see lifespans reaching the upper ends of those ranges if you get pumping done regularly and avoid putting chemicals and non-biodegradable solids down your drains.

Septic distribution boxes, also called D-boxes, tend to last over 30 years if taken care of extremely well. In most cases, however, they tend to last anywhere from 15 years to 40 years. Regular cleaning and maintenance, as well as living in an area that doesn’t flood the tank or the system regularly, will all have an impact on the lifespan of the box.

Yes. A septic tank riser is meant to replace a septic tank cover—concrete, metal, fiberglass, or otherwise—while still allowing easy access to the opening of the tank. Just as you would need to be mindful of the septic tank lid when it comes to mowing the lawn or other yard usage, you’ll have to be cautious not to damage or otherwise disrupt the septic tank riser.

You should avoid using any water in the home if your septic tank is full. Otherwise, it can lead to sewage backups and overflow because the outlet pipe is clogged, and the water has nowhere else to go. You also won’t be able to use water while your tank is being pumped. 

Several things can ruin a septic tank over time, including dumping harsh chemicals (like bleach and ammonia), pesticides, and paint thinners down your drain because they can kill the bacteria in your septic tank. You should also make sure to only flush waste and toilet paper in your toilet—otherwise, you could clog your system.
