How To Install A Sump Pump
Water Leak Sensor
Before using the wet saw I had to remove the water alarm sensors. The sensor is for the water heater and was tripped when the rain water entered and wet the basement floor last month.
Once this project is complete I will see if the alarm company will add a sensor in my sump pit, just above the pump as a early warning if the pump ever fails to turn on.
A Wet Saw Helps
I cut the outline with my wet saw.
The water keeps the dust down. A wet dry vacuum was used to clean up the water and help keep the area clean.
Nice clean saw kerf abetter alternative of a jack hammer.
Drill a Series of Small Holes
I used a 3/8″ masonry bit to drill small holes in the saw kerf -all the way through the concrete slab. I spaced these holes every inch or so.
I divided the space in thirds with two additional saw cuts and drilled through these as well.
This technique is useful since it causes the concrete to crack and break at the the drill holes and saw kerfs and no where else.
Using the chisel attachment to “jack hammer” the concrete apart. Breaking up the concrete in pieces.
Smash Through the Concrete
Trying to break up the concrete with a sledge hammer.
The end result is a nice clean hole opening. Ready to dig out. I had to remove the dirt in 5 gallon buckets – not fun. Time elapsed 3 hours.
