A sediment trap shall be installed when REQUIRED by the manufacturer of an appliance

Installing a sediment trap at the outlet of the meter is not practical, as it places the trap too far from the appliance's inlet. This distance can allow contaminants to bypass the trap and enter the appliance, negating its intended purpose.

While regular sediment traps are important, specifying every 25 feet is not a standard requirement. The placement of sediment traps should focus on proximity to the appliance inlet rather than a fixed distance, as this ensures optimal filtration of debris before it can affect the equipment.

Even if the gas supply is perceived as clean and dry, sediment traps are still recommended as a precautionary measure. They serve to protect against any unforeseen contaminants that may enter the system, ensuring the long-term safety and efficiency of the appliance.
