Bowen}1556 G.M.1, in which you state the valves were wrongly assembled. This pump actually failed on the road, which rules out the possibility that this was the cause of the failure in the first place, and as the pumps were not touched in any way, we can only assume that the valves were put back wrongly after the pump was inspected in your presence. We should be glad therefore if you would continue to test this pump in a similar manner to RB.{R. Bowen}759.G.M.1, and then give us some explanation as the original failures on the rig you witnessed. RB.{R. Bowen}1007 G.M.1. This pump you admit had a warped valve, probably due to wrong assembly of the retaining spring clip.
