Septic Tank Pumping - Every 4 Years Minimum

It is recommended that homeowners have septic tank pumping done every two to four years. But what makes it necessary to have a septic pumped?

The answer lies in how a septic tank works. When effluent goes into the tank, it takes about 24 hours for the solids to settle out of the water. Only about half of the solids get digested by bacteria during that time; the rest either settles to the bottom of the tank as sludge, or rises to become scum. Water remains in the middle layer. After about a day, this “clarified” water leaves the tank and enters the septic field.

Septic Tank Pumping - Added Insurance

As time goes on, the layer of solids can grow to the point that it starts to take up space that would normally be filled with water. This makes it so the water is pushed out of the tank into the septic field sooner. Eventually, this can mean that it doesn’t stay in the tank long enough for all the solids to settle out of it. If this happens, solids go into the septic field along with the water. This can clog the field and cause it to fail.

Therefore, septic tank pumping is done mainly to prevent the failure of the septic field. It is even possible for the tank itself to become completely full of solids if it is ignored long enough. Another reason to pump out a septic tank is to allow other maintenance or repairs of that end of the septic system. No repair person is going to go for a swim in the septage, so emptying the tank is a must in these cases.

How often septic tank pumping is necessary depends mostly on the size of the household. Sometimes the number of occupants is used as a guideline; others may base guidelines on the number of bedrooms in the house. A typical household will need septic tank pumping every two to four years, but if the load on the system is heavier – for instance if there’s a food disposal or clothes washer in use – the tank may need to be pumped out more often.

Septic Tank Pumping - Cost Effective

The cost of replacing a waste-clogged septic field is far more than that of preventative maintenance. If it’s been a long time since septic tank pumping has been done, you should schedule a pump-out as soon as possible. With regular maintenance of the tank, the septic system can work well for years.
