What is the pitch per foot for a drain pipe to the sewer system?

The recommended pitch for a drain pipe leading to the sewer system is typically 1/4 inch per foot (or about 2% slope). This slope ensures proper drainage and prevents clogs by allowing wastewater to flow smoothly through the pipe. In some cases, a pitch of 1/8 inch per foot may be acceptable for larger pipes, but maintaining the correct slope is crucial for effective drainage.
