Last week we completed a repair at a local, 30k gallon underground fire protection storage water tank. The fill pipe somehow got broken off and we replaced it with a new, Sch 80 PVC pipe and ETT (brand) fill fitting. The original fill pipe design was not the best and probably contributed to the break...plus, the old pipe was Schedule 40 foam core pipe and simply did not hold up to the stresses of a FD hose and water pressure. While we were at it we also replaced the existing suction head with a newer, ETT suction head. We finished everything up with a new coat of yellow, Krylon Fusion paint.
