installing a gas valve and sediment trap according to the UPC. there seemed to be a lot of confusion surrounding the location of the sediment trap on my posts in the past. UPC Section 1212.8, Sediment traps shall be installed downstream of the appliance shut off, as close to the inlet as practical, and BEFORE the flex connector. In this state we are required to use the flex connectors due to the amount of seismic activity. If you read this I hope you have a great day & that I cleared some things
