Basement Drains??

OK. I bought a house a year ago that is now 4 years old. In my basement the perimeter is cut out about 4 inches deep and 3 inches wide. The perimeter is covered in concerte. I have a sump pump pit but a sump pump was never installed. The sump pump pit has spots for three pipes to come through the ground and into the pit put they were never cut out. My pit is filling with water. After getting all the water out of the pit it just fills up again. The water seems to be coming from the bottom of the pit where a few holes were made. I also have water in the perimeter as well. My questions is what is going on. I have read all about basement perimeter drains and it seems that the drains should have a pipe that runs the water into the sump pit. But my sump pit is solid with the exception of the few holes at the base. Can someone please explain what is going on. I plan on having a sump pump installed in the morning. Once the water stops filling the sump pit will the water in the perimeter go away?? Thanks for your help.

It is not necessarty to pump out the pit unless it threatens to overflow or unless water seeps into the basement elsewhere.

If you do keep the pit pumped out (no more than 4 inches deep) the perimeter "gutters" should stay dry although if water came up into them the water might take some time to seep back down into the ground.

There exists a water level within the ground (called the water table) that may vary even between your front yard and your back yard depending on ground and soil texture and rainfall. By pumping the pit (sump) you depress the water table in the vicinity of the pit and hopefully depress the water table below floor level over the entire foundation area (footprint) of the house.

Perforated pipes are laid and buried around the foundation to collect water from the far corner of the basement more quickly and favor lowering the water table there rather than rely on random seepage and let the pump do more work lowering the water table in a more or less circular area around the pit and that encompasses part of the yard outside.

A perimeter drain as a ditch inside the foundation walls will work except that the large exposed water surface area will make the basement more humid and the entire ditch surface needs to be treated periodically to resist mold and mildew and moss.


The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.
