We consider networks Ç with the property that valves are installed in some of the nodes v. Entering v by an arc (u, v) and leaving it by another arc (v, w) is only possible if (u, v) and (v, w) are connected by a valve adjustment. A path [x1,..., xk] is admissible if a valve adjustment exists which connects each arc (xk, xk + 1) with (xk + 1, xk + 2).

We investigate the complexity of deciding whether there exists an admissible path from a node s to another node t of Ç.
