Script to Trace Water Mains to Fire Hydrant

[MatsHardy]

I have a line feature class of water mains and another point feature class of fire hydrants. The water mains are inter-connected and the fire hydrants are connected to the tips of the water mains.

Now, I wants trace from a water mains feature to all connected fire hydrants. Are there any functions in arcpy allow me to do so?

You might be out of luck if you are strictly an ArcGis Pro user:  This idea post is a coule years old and indicates that geometric network traces are an ArcMap only sort of thing: Support for Geometric Networks in Pro 

If your are an ArcMap user, start here: What are geometric networks?—Help | Documentation

Thanks to your help. But am I able to do the same things without geometric network? My company does not allow building network in geodatabase.

[JoeBorgione]

Perhaps, but that's beyond me.

In a more advanced way (partially arcpy) you could implement Dijkstra algorithm to check the data in a non geometric network. 

without doing any searching there might be an existing python implementation already you could use. If not the algorithm is pretty straightforward.

Thanks for your help. I am looking for arcpy scripts to search point features snapped on line features. Do you any arcpy functions to do so?

[CodyScott]

try this out. You can modify it to however you'd like once you download it.

Many thanks for your help
