7 warning signs your septic tank is full

  1. Strong odors of human waste from your septic tank or drains (see article on Why the sewage smell in house & septic odor neutralizing)
  2. Drains are slow to clear water
  3. Water pooling near your septic tank
  4. Very green lawn near the tank
  5. Sewer backup
  6. Pipe gurgling sounds
  7. Trouble Flushing your toilets


Strong odors of human waste/ raw sewage

This is usually one of the first obvious sign of an unhealthy sewage system. The bad odors or sewage smell coming from your sewage system can be a sign your tank is full, or it can be that your septic tank is not properly maintained. Basically, it is not happy and neither are the bacteria that live in your tank.

Drains are slow to clear water or draining slowly

If you have slow drains or water is slow to drain in your shower, kitchen sink, bathroom sink, washing machine or multiple drains in the house, this can be a sign that your tank is full or there is a clog in one of your lines. This is an easy one to spot as you know the normal level or speed of your drain empties, especially the lowest drains.

Water pooling

Pooling water or standing greywater/ wastewater around your yard or specifically near your septic tank and in the drain field or drainage area is a warning sign that your septic tank is overfilled or not dealing with the wastewater generated. It can be hard to measure this if you live in a state that has a lot of rain. If you also look at the next sign, that the grass in your yard is overly green, these two can combine as a potential sign of a major problem.


Don't wait for your septic tank to fail

Very green lawn near the tank

If you have patches of greener grass in your yard and you haven’t applied extra fertilizer recently, this could be a sign of a full tank or your tank needs to be emptied. Look specifically near your tank, if your tank is overflowing at night or when you are not around, this could show the problem.

Sewer backup

Sewage backing up is a sure sign that your septic tank system or plumbing works are having major problems. This can be a potential health risk for you and your family. Of the several warning signs, this warning sign is one to take notice of and take action on. Engage a plumber or septic tank maintenance company to visit your property and diagnose the problem, to establish if you need to have your septic system pumped.

It can be a sign that the septic tank is full and it is not easily accepting the water you are putting into the septic system. Slow drains are also a common associated symptom.
