How often should a septic tank be pumped?

The widely published advice is to have a household septic tank pumped every few years, and the right timing for yours depends on the size of the tank and how much water and waste your household sends into it. A large tank with a small household can go longer between visits than a small tank with a full house.

Why does a septic tank need pumping?

Wastewater from the house flows into the tank, where solids settle to the bottom and grease and other light material float to the top. The liquid in the middle flows out to the drain field. Over time the layer of solids grows, and pumping removes it before it gets high enough to follow the liquid out of the tank.

Solids that reach the drain field can clog it, and repairing a drain field can cost more than a pumping.

What changes how often your tank needs pumping?

These move the timing:

No one number of years fits every combination of these. Ask the company that pumps your tank to suggest an interval for your tank size and your household.

How do you know when it is time to pump?

Pumping on a schedule is usually simpler than waiting for a sign. Slow drains, gurgling pipes, odors, and wet or unusually green patches over the tank or the drain field can point to a full tank or to another septic problem. They can also come from the plumbing inside the house, so a visit from a company is how you find out which.

Keep a record of each pumping: the date, the size of the tank and what the company told you about how full it was. With that history, the next company can suggest when to come back. If you bought the house and do not know when the tank was last pumped, ask for any records from the seller or have a company check how full the tank is.

The size of the tank, how easy the lid is to find and reach, how many tanks or compartments there are and what the visit includes all move the price. See what moves the price of septic tank pumping. A lower price may cover less, such as a smaller tank size or no digging for the lid, so compare what each company lists and not just the total.
