Hi Chief,
I read with interset about your going to 3 1/2" line. When I joined the department I am in we had 3" supply line with 2 1/2" couplings. We loaded it with 1000', and a divider with 500' on either side. This was so we could lay siamese 3" lines, of which the flow at the time was just as feasible as 4" and less expensive. A lot more hose on the ground though. In 1986 we replaced two pumpers and went to 4" line and fittings and have used this ever since. With the 3" line our SOG was to make sure all outlets on the hydrants were gated so we could theoretically lay 4-3" lines from one hydrant, using 2 gates and a 2 gated steamer "Y". Good luck as Chief.
