India MKII vs VLOM issues

We've encountered some differences between our design and the actual construction. Most of them have been no big deal, and mostly a difference between the equipment that we're used to and what is available here. This one might be big however - the driller has been unable to find a VLOM "Village Level Operation and Maintenance" cylinder for our pump. We're researching exactly what that means and how different that makes the maintenance. Obviously we want the village to be able to maintain their pump to the maximum extent possible - hopefully we can get this resolved quickly...
