6 Signs You Need Your Septic Tank Pumped

There are several tell-tale signs that your septic tank could be in need of pumping out. Mac Plumbing gives you some tips on what to look for

Pooling Water

  • When your septic tank is full, solid waste can clog the drain field piping system and force liquid to the surface.
  • If you see pooling water in your lawn, it’s best to check to see if you need your system pumped.

Slow Drains

  • Slow-moving drains could just mean a clogged drain. However, if they remain slow even after unclogging, the system may be full.


  • This is the worst sign that your septic system may need to be pumped.
  • The septic system not only collects waste but also all the “gray water” from showering, washing clothes, and dishes. This combined with the black water from toilets creates an odorous mixture.
  • If you catch a whiff of any unpleasant odors in your yard, it may be time to call Mac Plumbing to have your tank pumped.

Really Green Area of Grass

  • The grass over your septic bed should look the same as the grass everywhere else.
  • If it appears overly green or lush in that area, this could indicate your septic system is leaking or needs to be emptied.

Sewer Backup

  • This is the most obvious and messiest sign that your tank has reached capacity.
  • Look for sewer backups in the lowest drains first, like in the basement bathroom.
  • If you see sewage backing up, call Mac Plumbing immediately.

Additional tips:

  • Remember, anything you put down your drains ends up in your septic tank.
  • Always use green cleaners and paper products that are septic-safe.
  • Refrain from overloading your septic system with other contaminants.
