Posted November 2, 2015 I've noticed the OCFA still lays 3" duals for supply lines. It seems like everyone else is so cal is using 4" and 5" inch LDH. Is there a special reason for this or do they simply prefer laying duals? Share this post Link to post Share on other sites
Posted November 7, 2015 Most OCFA rigs have 4 inch supply hose. Only WUI engines and reserve units still run 2 1/2 and 3 inch Share this post Link to post Share on other sites
