What do you folks do for fittings that are bolted to one another? For example, a reducer bolted to a tee? I just added a fittings layer with the intent of eventually putting my system into a geometric network. So far I have just put the fittings on top of each other as coincident points. Is this even an issue I should be concerned about? With wet taps, I have placed a wet tap fittings at the intersection of the pipes and place the tapping valve offset from the fitting by the approximate distance from center to center of the fitting to the valve. So if I decide to split mains at valves in the future (likely), I will end up with 1-2' pipe segments.
Any advice is appreciated!
