More isn’t always better. We found excess CSST gas piping connected and coiled in a crawlspace when only a fraction of that length was needed to reach the appliance.
Gas piping systems are sized based on factors including pipe diameter, developed length, available gas pressure, and the demand of the connected appliances. Adding unnecessary length increases pressure loss and can reduce the capacity of the piping system.
CSST is a great product when properly sized, supported, bonded, and installed—but the goal is to provide an appropriately sized route to the appliance, not store the extra 50 feet in the crawlspace.
