Regular inspections play a vital role in keeping your septic system working properly. They help you spot early signs of deterioration so you can take action before there’s more costly damage. Cox’s Septic Service in Corbin, KY, says determining when to schedule a professional inspection depends on several factors.

Their experts list three indicators of how often you should have your septic system inspected:

• Size: The size of your septic tank is important to how often you will need inspection, pumping, and cleaning services. A 500-gallon tank may need annual service, while a 2,000-gallon tank could go 5–6 years before inspection and pumping are necessary.

• Usage: The number of people using your septic system also is a guideline for how often it should be inspected. If you have a large household, you may need an inspection every 2–3 years. For an average-sized family, professionals suggest inspecting and pumping the system every 3–5 years.

• EPA Recommendations: The U.S. Environmental Protection Agency suggests having your septic tank inspected and pumped every 3–5 years. This will prolong the life of your system and keep its components in working order.
