What is the correct pitch for a 10 foot refrigeration line?

The correct pitch for a 10-foot refrigeration line is 1/4 inch. This measurement is critical to ensure proper drainage of refrigerant oil back to the compressor, particularly in systems using refrigerant lines that may accumulate oil or moisture. A 1/4 inch pitch per 10 feet means that the line should fall by one quarter of an inch for every 10 feet of length, which promotes efficient flow and helps prevent issues such as liquid refrigerant from collecting in the lines, which could lead to compressor damage or inefficiencies in the refrigerant cycle.

Using this specific pitch balances the need for effective refrigerant flow with the operational requirements of the system, thereby enhancing performance and reliability. Additionally, adhering to the correct pitch can help avoid problems during installation or when servicing the refrigeration system.
