I am trying to migrate plumbing fixture unit data from plumbing fixtures through pipe. Data will migrate successfully through elbow fittings. Data will not migrate through Tee fittings. (See attached image) I have tried to connect generic fittings and vendor built fittings, and the result is the same. I have tried changing the System Classification and the Flow Configuration of the Pipe Connectors, and the data won't flow through the Tee Fitting. This problem occurs with Domestic Water pipe as well as Sanitary Waste Pipe. I have tried linking and unlinking different combinations of Pipe Connectors within the Tee Fitting families. The Elbow Fittings I have used that migrate data correctly have Pipe Connectors set to the "Fitting" System Classification. Adding a third connector seems to prevent data migration. I would appreciate any suggestions.
