When to Pump the Septic Tank When Buying a Home InspectAPedia®  -     Chapter 5-How to Inspect and Test Septic Systems for Home Buyers - Step 4 - Pump the Septic Tank Step-4: When & how to pump the septic tank if you are buying a home Details of How to Inspect & Test Septic Systems When Buying A Home

This document provides advice for home buyers who are buying a property with a private septic system, that is, a septic tank and a leach field or drainfield or similar soil absorption system. Chapter 5 in this file describes detail: questions to ask about the septic system, how to perform the visual septic inspection, ordering the loading and septic dye test (the too-obvious results of a dye test at a problem site are in the photo at left), pumping the septic tank, and finding additional information about the septic system.

We explain how to be sure your septic inspection and septic test are conducted properly. We tell you where to get more septic system information about a given property, and we warn of unsanitary or dangerous site conditions.

5-4. PUMP THE SEPTIC TANK When & How to Pump the Septic Tank When Buying a Home

Warning: [Repeated from the Dye Test discussion] Do not pump the septic tank before the loading and dye test. Depending on its size an empty septic tank could require 2-3 days' worth of water to re-fill the tank. An empty tank means that the "loading water" run into the system during the dye test procedure is simply filling the tank rather than testing the ability of the drain field to absorb effluent.

Pumping a septic tank prior to purchasing a home may or may not be necessary, depending on the age and service history of the system and the results of the visual inspection and loading and dye test. For example, if a tank is less than two years old or was pumped in the last year, and if there are no other signs of septic problems at the site, we might defer the pumpout. In this case we would strongly recommend calling the pumper to ask about the condition of the system at the time they last cleaned it.
