Where should a sediment trap be installed in relation to the equipment's shut-off valve?

A sediment trap is designed to collect contaminants such as debris and sediment that may be present in the gas supply line, preventing them from entering the equipment and causing operational issues or damage. Installing the sediment trap downstream of the equipment's shut-off valve ensures that contaminants are captured before they reach the appliance or fixture that requires a clean and uninterrupted gas supply.

When positioned downstream, the sediment trap functions effectively by allowing any sediment or debris to settle out of the gas stream after the shut-off valve, thus protecting the equipment. This placement ensures that maintenance can still be performed on the equipment without disturbing the sediment trap, and it minimizes the risk of contaminants flowing back through the shut-off valve into the gas supply system.

Positioning the trap upstream or at the same level could risk allowing contaminants to enter the system, jeopardizing the equipment’s performance. Similarly, locating it near the discharge point might not capture the sediment effectively or could lead to further operational complications. Hence, proper installation downstream is essential for the trap's intended function.
