As you can imagine, we don’t have much more than minutes of heads up when there is an emergency, we must make sure (double and triple check!) that our equipment will operate as we expect it to when we need it.
That’s why all our water-pumping apparatus is regularly pump tested.
In this instance, we are using a specialized trailer that we can recycle water, and get good readings on the suction and pumping capability of all water pumps.
