Create a continuous pipeline between the tap and the overflow pipe. Rotate the pipes by clicking on them. Once you've connected the pipes click the tap to go the the next stage. Plumber 2 provides update graphics, more challenging levels (25 in all and twice the board size of the 1st version) and no time limit to bog you down. Be aware of the overlapping pipe connections as it adds an extra 3D layer which can be somewhat confusing. If you get stuck, try to work backwards.
