The Proper Use and Maintenance of Water Softeners

Hartford Steam Boiler investigates many claims in which scale build-up leads to leaks in boiler tubes. In one incident, the insured blamed a water treatment company for faulty treatment. A review found that some time before the incident, the insured had altered the feedwater train through the softeners. The softener piping was changed so that the units operated in series instead of in parallel. The only advantage gained by operating the units in series would be longer times between regenerations. However, since both beds would be spent, the system would have to be shut down completely for regeneration unless an adequate supply of condensate was available. Operating the softeners in series allowed the hardness into the system that contributed to the scale build-up.»more

The Human Factor in Equipment Failures

Outside factors can defeat any system. That’s why pre-planning and an appropriate response by operations personnel are important. In one case, serious damage resulted in the fire suppression system of a 27-story office building. The system consisted of a 2 hp jockey pump, 1,000 gallon per minute engine-driven fire pump, and the associated sprinkler piping, alarms and electrical controls. The fire pump was controlled by a pressure switch during normal operation. As the pressure in the fire protection system decreased, the jockey pump restored the system pressure to normal parameters. If the pressure continued to drop (signifying the possible actuation of the sprinkler system) the fire pump automatically actuated to deliver water to the building’s sprinkler system.»more

Poor Lighting, Sloppy Storage Result in Chiller Breakdown

Since air conditioning was extremely important to its business, a large department store had frequent scheduled maintenance performed on its equipment.
