Breaking basement floor to install new drain/sanitary line

[M Lindgren]

I recently had a sanitary line fail under the basement floor. The plumber wanted an extra $2500 to break up the floor and dig the trench. I told him I would do that part to save the $$$. I did it the old fashioned way-sledge hammer and pick. It was clear about 5 minutes in that the smart way is with proper equipment.

Question is, what is a better tool to buy, an electric demolition hammer or a concrete saw? Most of my houses were constructed pre-sump pump days. I would like to start adding basement drainage systems and sump pumps when I first buy the properties.

Thanks in advance!
