Because pumps are zero length channels they do not create automatic nodes at the upstream and downstream end. If you ran the model with just a pump polyline and SX connection you will get [[TUFLOW_Message_1353| <font color="red"><tt>ERROR 1353 - No NA data for Node</tt></font><tt>.</tt>]]To remove this error,

To connect the pump to the 2d domain you will also need to digitise an SX connection. In the figure below I have showed both the 1d node and 2d SX points as being separate from each other for illustrative purposes only – they should both be snapped to the end of the pump polyline. SX connections are required at connections to 2D domains to transfer water from the 1D node to the 2D. Without the SX connection, water will build up within the node and cause an instability. <br>
