Septic system installations and replacements FAQs

A septic tank typically lasts 15 to 20 years, depending on the materials used, maintenance frequency, and soil conditions. Regular inspections, proper pumping, and careful water usage can extend its lifespan. Professional maintenance ensures your system remains efficient and helps prevent premature failure.

Your septic tank should be pumped every three to five years. In fact, the recommended interval for pumping is every three to five years, as this schedule effectively prevents the buildup of solids and maintains the system's performance. Factors such as household size, water usage, and the capacity of the tank can influence this interval. Adhering to a regular pumping schedule minimizes risks of backups and system overload, ensuring efficient operation and longevity of your septic system.

Your septic system shows signs of failing when you detect noticeable odors and unusual moisture or overly green patches in your yard. In essence, clear indications such as unpleasant smells, gurgling noises from the plumbing, and areas of excessive vegetation or saturation signal that the system may be compromised. Additional symptoms include slow drainage and standing water near the drain field. These warning signs require immediate professional evaluation to prevent severe damage or environmental hazards.
