Pump-outs on an interval that matches your house, not a scare ad.

Tennessee doesn't force a calendar on every conventional tank. TDEC and the EPA still point most homes to something like every 3 to 5 years, sooner with more people or a garbage disposal. In clay country, skipping years is how fields die.

When to call

• You're past 3-5 years
• You moved in with no records
• The disposal runs daily
• You're selling and the buyer asked
• Odors or sluggish fixtures (we'll say if you need repair instead)

Local wrinkle

Truck access on terraced or hillside lots matters. So does finding both lids. If you don't know where the tank is, say that up front. We'd rather locate than drive twice.

What we do

• Confirm access
• Open lids
• Pump
• Note obvious red flags (roots, missing baffle, high water)
• Help you set the next interval

Try the estimator at When to pump if you're unsure. It will not invent a failed field from your ZIP.

Routine pump-outs typically do not need a construction permit. Digging, tank replacement, and field work are a different story.

Price drivers

Tank size, distance, dual compartments, after-hours, how buried the lids are. Market chatter often sits around $300-$600 for a standard residential pump-out. That's a market range, not a bid.

Quick answers

**Is there a Tennessee law that says every 3 years?** No single statewide deadline for every conventional system. The 3-5 year band is guidance, then we adjust for your house.

**Do additives replace pumping?** No. Keep grease out of the tank. Don't treat a bottle of "starter" as a substitute for a truck.
