I have a customer that lives in an old farmhouse with dirt/bedrock basement floor. She wants to put in a sump pump. Suggestions on approach, demo saw and jack hammer?

Dug a hole in basement floor. Put in 5 gallon pail in hole. Plastic lid on pail with small holes drilled in lid. Pump in pail with auto valve. Works.

That’s the approach I would take.

Might be better, with a plastic, garbage can. or something similar. would give a larger volume of water before pump started. less cycling of pump. old 243

Guys, I think Mike is asking how to get the hole in bedrock. I’m pretty sure he knows how to install a liner.

Dirt and bedrock are two different things. If it was rock proper, and you had to have a hole the size of a 5gal bucket i would rent a concrete chain saw. Cut a perimeter, then grid it out a bit. You can used a splitting wedge to start to break the rock sort of like when you kerf a board a bunch and clear it with a claw hammer.
