What is a maximum single line length for perforated pipe in a drainfield?

The correct answer reflects the recommended maximum length for a single line of perforated pipe in a drainfield, which is 150 feet. This specification is important because if the lines are too long, it can lead to insufficient distribution of effluent, increased risk of clogging, and inadequate treatment of wastewater.

Maintaining the maximum single line length ensures that the system has a good flow rate and allows for proper aeration and filtering of effluent through the soil. By adhering to this standard, an installer can help prevent issues that might arise from longer lines, such as uneven distribution, which can ultimately impact the effectiveness and longevity of the on-site sewage facility.

When planning a drainfield, it's crucial to design these configurations within established guidelines to promote optimal performance and compliance with health regulations.
