After the septic tank is nearly empty the operator might connect a garden hose to wash-down the tank baffles, septic tank sides, and tank bottom. The pump will continue to run to remove the excess water that is entering the tank.

This step is not mandatory, and some septic pumping contractors leave it out. But if it is performed we have an opportunity to better inspect the septic tank sides and bottom for cracks, breaks, or spalling. In sum, washing the septic tank permits a more careful inspection of the condition of the septic tank interior.

The additional water in the septic tank and any remaining bottom debris is washed out at this time.

The need for septic tank interior washing depends on the tank type, age, and conditions which may require extra water for final sludge removal or wash-down to permit inspection of suspected problems such as a rusted-out tank bottom or missing tank plug. Certainly if the effluent levels in the tank were abnormally low at the start of pumping, this wash-down and detailed inspection is a good idea.

Incidental bits of masonry debris in the bottom of the septic tank such as chips from a concrete cover, stones, or old terra cotta waste line which happen to remain on the tank bottom may remain in place and are harmless.

If septic tank damage is found such as cracking, it may be possible to repair the septic tank by cleaning the surfaces and applying an appropriate masonry patching compound. But no one should enter the septic tank without proper equipment or preparation as there is a real danger of death by asphyxiation by the methane gas remaining in the tank.
