When a house on a septic tank or cesspool backs up, there are two possibilities: the line from the house is clogged, or the system itself is full or failing. We clear the line, which tells you which one it is.

What we do

  • Clear the house drain line from the house to an existing septic tank
  • Clear kitchen, bath and laundry lines that feed it
  • Repair the drain line inside the house

What we don't do

  • No septic system installs. We don't install septic tanks, leaching systems or advanced treatment systems.
  • No cesspool work of any kind. We don't pump, repair, replace or abandon cesspools.
  • No septic tank pumping

How it works

  • Clear the line. If water goes down once the line is clear, the problem was the line.
  • If it still won't drain, the tank or the system is full or failing. That's a job for a cesspool or septic contractor, and we tell you so.

Cesspools and septic on Long Island

Much of our area isn't sewered. Laying Suffolk County's sewer-district map over the Census boundary shows essentially none of Brentwood in a county sewer district, and Nassau County's health department lists communities such as Muttontown as not publicly sewered. Suffolk County says about 250,000 of its cesspools pre-date its 1973 rule requiring septic tanks on new construction, and since July 1, 2019, a failed cesspool can't be replaced with another cesspool; a conventional septic system is the minimum.

Questions

Septic Line Clearing FAQ

How do I know if it's the line or the tank?
If one fixture is slow, it's usually that fixture's drain. If everything is slow and clearing the main line doesn't fix it, the tank or cesspool is likely full or failing.
Do you pump septic tanks or cesspools?
No. We clear the line from the house. Pumping, repairing or replacing a septic tank or cesspool is a job for a cesspool or septic contractor.
Can you install a new septic system?
No. We don't install septic systems.
