Cleaning out your septic tank is one of those chores you can't neglect or you won't be able to flush your toilets without sewage backing into your house or spilling into your yard. Fortunately, you don't have to do anything other than call a contractor when it's time to clean your tank. Here's how septic cleaning is done and why it's so important to do it before your tank gets too full.

A Septic Tank Is Pumped Out

Cleaning a septic tank is a matter of pumping out the contents. The contractor arrives with a pump truck that has a long hose on it. The hose is lowered into the tank and the contents of the tank are pumped out and collected in the truck.

The contractor might stir the contents of the tank to work the sludge loose that's stuck to the sides. They want to remove the fatty layer that floats on top, the liquid that's in the middle, and the sludge that's on the bottom so the tank is as clean as possible.

You need to work with a contractor for septic cleaning because they can dispose of the waste legally in a dumping site designated for toxic waste. Plus, the waste and fumes from the tank are dangerous to work around, so it isn't safe to attempt DIY septic cleaning.

A Light Inspection Is Done At The Same Time

You may be required to have a full inspection of your tank every few years, and the contractor will do a light inspection when they pump out your tank too. This catches problems early before your yard is contaminated with sewage.

The contractor looks for clogs and checks the condition of the baffles in the tank. They'll also watch for backflow as the tank is emptied since backflow could indicate a problem with clogging in the distribution box or drainfield.

A Well-Maintained Tank Prevents System Damage

An important reason to have septic cleaning done on schedule is to protect the drainfield. A drainfield can be expensive to repair or replace if it gets clogged with sludge or biofilm. Your tank needs to be cleaned before the sludge layer gets too thick. Otherwise, solids can escape the tank and clog the baffles, distribution box, or drains and soil in the drainfield.

Besides problems with clogging, a full septic tank can create a toxic hazard on your property when it overflows. Rather than wait until your tank shows signs of being full, have your tank emptied on a schedule that ensures your tank won't get too full and clog your system or overflow.
