These two units weighed 500 pounds each. I was really worried that these young men would hurt themselves carrying these two units in or bang up the building or the units. Elder Anthony found out that they didn't bring the pumps so we have more to be delivered but hopefully they can start installing. It should take about two weeks. An electrician has to come in and do his part. A pipe guy the heating specialist and I don't know how many other. The weather has started heating up so hopefully we have the time before things get really cold.
