What is the minimum pitch of rise required when installing a connector?

The minimum pitch of rise required when installing a connector is set to ensure that proper drainage and venting are achieved. A rise of 1/4 inch per foot allows for adequate flow of condensate or exhaust gasses, helping to prevent issues like water buildup or inefficient operation of the system. This slope facilitates the movement of materials and prevents blockages, ensuring that the connector functions as intended.

In many mechanical codes, a pitch of 1/4 inch per foot is considered a standard that strikes a balance between effective drainage and practical installation, which is why it is established as the minimum requirement. This ensures compliance with safety and functional standards in installations.
