Cesspool or clogged line? How to tell

Most homes around Smithtown drain to a cesspool, not a sewer. When drains back up, knowing which problem you have saves a wasted service call.

Signs it's a clogged line

  • Only one fixture, or one bathroom, is slow.
  • The problem started suddenly after something went down the drain.
  • The yard over the cesspool looks normal.

Signs the cesspool may be full

  • Every drain in the house slows down at the same time.
  • Backups get worse after laundry, long showers or heavy rain.
  • Soggy ground, sewage odor or lush grass over the cesspool area.

The cleanout tells you a lot

Your main cleanout is a capped pipe where the drain line leaves the house, often in the basement or near the foundation outside. If a plumber opens it and finds standing water, the blockage is beyond that point: either the line to the cesspool or the cesspool itself. If it's dry, the clog is inside the house. Don't open a cleanout yourself if drains are backed up; it can release sewage.

What we do: we clear lines and tell you honestly if the cesspool is the problem. We don't pump cesspools, so if that's what you need, we'll say so and you can call a licensed cesspool company directly.
