Spiliotis and Tsakiris (2011) show the nodal formulation for water distribution system analysis using the head-loss dependent Jacobian. Some issues about the node formulation of the discussed problem will be commented on here. Also, as an addition to the discussed paper, the procedure with pressure drop formulation of the Jacobian will be presented where the method is similar to, but different from Spiliotis and Tsakiris (2011). The procedure uses elements of the methods by Cross (1936), Shamir and Howard (1968) and Epp and Fowler (1970).
