Septic tank pumping costs $250 to $895, depending on the tank size and location. Pumping may cost as little as $250 for a 750-gallon tank, or as much as $895 for a 1,250-gallon tank.

Completely replacing a damaged septic system can cost up to $10,000, compared to the price for regular pumping. Proper maintenance can help a septic tank last for up to 50 years.

The Environmental Protection Agency recommends inspecting and pumping your septic system every 3 to 5 years. Septic pumping frequency depends on the number of residents, the amount of wastewater generated, the volume of solids, and septic tank size.

Professionals should also inspect the system every 3 years to look for leaks and layers of scum and sludge. The tank needs pumping when the bottom of the scum layer is within 6" of the bottom outlet tee, or the top sludge layer is within 12" of the outlet tee.

However, if you suspect your tank is full, don't wait until then to call a professional.

Pumping a septic tank takes 20 to 60 minutes, depending on the tank size, volume of waste, and equipment used. During this time, the technician will:

• Note the tank’s liquid level and make sure there’s no leaking
• Lower a specialized vacuum hose into the tank
• Pump the waste to their truck
• Watch for backflow
• Backflush the tank to rinse off any remaining sludge
• Inspect the tank for any damage

Septic tank companies have the skills and equipment to pump and clean a septic tank safely and efficiently. Routine septic cleanings can help keep you flushing without issue.

If you have a clog, you may be unsure whether to call a plumber or a septic service. Call a septic service if there are numerous backed-up drains, a gurgling sound when you flush the toilet, or you have sewage odor or a soggy patch above the septic tank buried in your yard. Call a plumber if only one or two drains appear affected

Your septic tank may be full if:

• Your toilets are draining slowly or backing up.
• There are foul odors in the home.
• Your grass is greener than usual above the tank.
• There's standing water in your yard.
