Dry system main piping shall be pitched at ______ per 10 feet.

The proper pitch for dry system main piping is essential to ensure that any condensation that might form in the piping can effectively drain away and that the system operates correctly. When the piping is pitched at a rate of 1/4 inch per 10 feet, it helps maintain proper drainage and prevents water accumulation within the dry pipes, which could otherwise lead to operational failures or system malfunction.

This specific pitch allows any condensation to flow toward the designated drain points in the system, minimizing potential issues associated with water accumulation, such as corrosion or freezing. Ensuring that the dry system piping maintains this pitch is critical for effective performance and compliance with relevant codes and standards in fire protection.
