Break Concrete Floor — Break Concrete and Dig Trenches
Part of project
How to Rough-In Plumbing for a Basement Bathroom · Step 2 of 7
In this video
Once the water is mostly removed, the concrete floor needs to be broken to create an opening for the sump pump basin. A long digging bar is used to forcefully strike and break up the concrete slab. The video mentions that a saw was also used previously to make initial cuts, which simplifies the breaking process. This is a physically demanding step, performed in a wet and confined space.
Goal: Create an opening in the concrete floor for the sump pit
- Wear safety glasses and heavy-duty gloves when breaking concrete to protect from flying debris.
- Using a rotary hammer with a chisel bit can make breaking the concrete much easier than using manual tools.

FAQs
How difficult is roughing in basement bathroom plumbing for a DIYer, and how long does it typically take?
This project is rated intermediate due to the need for precise measurements, concrete work, and understanding plumbing codes. For an experienced DIYer, it can take 3-5 full days of work, not including permit acquisition and inspection wait times. Beginners should consider professional help for critical steps like concrete cutting and main line tie-ins.
What permits do I need, and how do I ensure my rough-in plumbing passes inspection?
You will almost certainly need a plumbing permit and possibly a building permit. Contact your local building department early in the planning phase to understand all requirements, necessary inspections (like the rough-in inspection), and specific code regulations for pipe sizing, slope, and venting to avoid costly rework.
What's the best way to break up the concrete floor, and what safety precautions should I take?
A demolition hammer or electric jackhammer is highly recommended for efficiency, which can often be rented. Wear heavy-duty work gloves, steel-toed boots, eye protection, hearing protection, and a dust mask to protect against concrete dust and flying debris. Be mindful of existing utility lines marked during the planning phase.
What are the most common mistakes when installing the underground DWV pipes, and how can I avoid them?
Common mistakes include incorrect pipe slope, inadequate solvent welding, and insufficient depth for drain lines. Ensure a consistent slope of at least 1/4 inch per foot for proper drainage, use proper primer and cement for strong, leak-free joints, and confirm all pipes are securely bedded in gravel to prevent shifting.
