How Often Should My Septic Tank Be Pumped Out?

Just like regular maintenance on your vehicle extends the life of the engine, scheduled maintenance on your septic tank will prevent major damage to your septic system. Not only preventing expensive septic system repairs, including seized pumps, blocked drainlines, and clogged effluent filters, regular maintenance may also prevent costly back-ups that could create permanent damage.

Septic Tank Pump Out

If a septic tank is not pumped regularly, solids will eventually escape into the septic drainfield, causing the soil pores to get clogged. While pumping frequency is dependent upon the amount of use, Lentz Septic Tank Service recommends that residential systems be pumped at least once every three – five years if your home does not have a garbage disposal. If the home’s system has a garbage disposal, or if anyone in your household is on medication, it should be pumped every one – two years.


If you are a commercial septic system owner, you should determine how often to pump based on prior accumulation and pumping records. Often you can look at pumping intervals to gauge your pumping schedule. For example, did you wait too long before having your tank pumped last time, or could you have waited a little longer to pump?


An amazing number of system owners believe that if they aren’t having any problems with their system, the tank doesn’t need to be pumped out. This is a serious and sometimes costly misconception, as the septic system repair or replacement cost alone could be thousands of dollars. If you add the expense of replacing your landscaping, lawn, and wastewater damage inside your home, the price you could encounter for neglecting your system can get quite costly.


The purpose of a septic system is to store wastewater in a tank where the solids eventually form a sludge layer. As your system is used, solid materials settle to the bottom of the tank, forming a sludge layer. Grease and lightweight materials float to the surface of the septic tank as scum. The clear water near the center is released into the septic drainfield. Normally, properly designed tanks have enough space to efficiently store up to three to five years of accumulated sludge. When the sludge level increases beyond this point, sewage has less time to settle properly before leaving the tank. As the sludge level increases, more solid wastes escape into the soil absorption system (SAS). If the SAS becomes so clogged with this sludge that it can’t absorb liquid at the rate in which it enters the tank, the plumbing will backup or unsanitary wastewater will bubble up to the drains inside your home.


Professional Septic Tank Pumping
When hiring a pumper, be sure the company you choose is licensed, and always make sure you get a paid receipt from the pumper that spells out the details of the transaction (how many gallons were pumped out of the tank, the date, the charges, and any other pertinent results). Retain this receipt for your records, and make a note on your calendar to schedule another pumping in one – five years, depending upon your situation.
A reputable pumping service provider will pump both sides of the tank, making sure that all of the waste on both sides of the baffle are clean and completely empty.

  1. I guess I must be one of those people who thought that you don’t need septic pumping if there’s nothing wrong. I’ve been at my new house for about two years, and I haven’t done anything with the septic system because it seemed to be working fine. Maybe I should have it pumped before something goes wrong and it has to be replaced, as you mentioned.

    1. Call us anytime if you have any questions or concerns, the recommended time for septic tank maintenance is 3-5 years. The good thing about maintaining your septic tank is that our professional technicians can see if any problems are starting as your tank ages. 704-876-1834


  2. Thanks for going over some reasons to pump out a septic system. It’s good to know that if you aren’t having any problems you don’t need to pump it out, expect for the maintenance every 3 to 5 years. It definitely sounds like it could be good to keep different signs of a problem in mind so that the situation can be fixed quickly.

  3. My wife and I recently bought a home with a septic system, but we aren’t sure when it was last pumped out. I like that you mention how, even if the tank isn’t having problems, doesn’t mean it doesn’t need to be pumped. We might have to do this soon just so we know that it’s been pumped recently and won’t break down on us.
