Septic tank pumping Long Island professionals say that there are some common mistakes that people make when it comes to pumping septic tanks.

Pumping too frequently

This is mistake seen with people who rely on unscrupulous contractors. A contractor is out to make money. He will be happy to pump whenever asked to. Some contractors will advise pumping after a few months or even after having many visitors.  Frequent pumping is just a waste of money.

Waiting until the flush does not work

When you leave everything to chance, everything is bound to go wrong. The day the toilet stops flushing means the drain field is too saturated and nothing else can be done to remedy this except to look for another drain field. Thinking that pumping will fix a clogged drain field is throwing good money away.


Cesspool Pumping Long Island professionals say that a properly installed septic tank has enough allowance for three to five years of the sludge of a typical household of 4-6 members. When sludge rises above the allowed mark, sewage does not settle in the septic tank. This leads to sewage damming in the plumbing, or waste water bubbling to the surface at the site of the drain field.


For typical households with 4-6 members, it is recommended that pumping is done once every year if the house has a garbage disposal system connecting to the septic tank. If there is no garbage coming into the sewer, the pumping can be done every three years.


Inspecting a septic tank can give a very good idea if there is a need for pumping. This is more advised if you don’t know the history of the septic tank. An inspection will yield details on;

  • Size of the tank
  • Sludge layers and the thickness of the scum
  • Signs of any problems like a blockage, clogging and cracking

If it is possible to find records showing when the last pumping was done so much the better. You can also gauge the level of usage since the last pumping was done, and any problems that have arisen since then.

Electronic monitoring

This is an easy way of keeping track of the levels in the septic tank. These data monitors can track sludge, grease and scum levels such that it is possible to schedule pumping and grease cleaning. However, visual inspection is also advised from time to time in case the data monitor fails.

Visual inspection can also be done using a video system so as to reduce the risks associated with strong smells from the septic tank.
