Strategy Employed

The problem was solved using a constraint propagation algorithm that prunes out the search space followed by a depth limited first search to generate the state nodes for uncertain actions.
When selecting the next action to perform we used the Most Constrained Variable (MCV) in order to choose pipes with the least possible options.
