UL Field Inspections. Yesterday we were greeted at the front door by our UL Inspector for an unannounced field inspectionâ¦surprise! At another facility there might be a cry for alarm, but at Coast Label Company there was no mad scramble, no rush to hide this, or go find that. We just sat him down and asked what he was checking today.
Jet pumps create suction in a rather novel way. The pump is powered by an electric motor that drives an impeller, or centrifugal pump. The impeller moves water, called drive water, from the well through a narrow orifice, or jet, mounted in the housing in front of the impeller.

We don't see most of the expensive machinery in a pool system, because it's usually tucked away in nearby pump room.

In a typical pump system, an electric motor spins an impeller inside the pump housing.The impeller drives the water from the various drains through the filter and back out to the water inlets.ut this is the stuff that really makes the pool work.
