Back pressure can force an undesirable contaminant to enter potable water piping. Sources of back pressure may be boilers, heat exchanging equipment, power washing equipment, fire sprinklers, or pumps in the water distribution system. In some cases there may be an almost continuous risk of overcoming the static water pressure in the piping.
Dehumanization is identified as one of the mechanisms of moral disengagement, as it justifies treating others with less moral concern and empathy, and therefore validates violent or abusive treatment towards others. [42] Dehumanization involves the moral exclusion and delegitimization of others. [43]
Dignity taking is the destruction or confiscation of property rights from owners or occupiers, where the intentional or unintentional outcome is dehumanization or infantilization. [1] There are two requirements: (1) involuntary property destruction or confiscation and (2) dehumanization or infantilization. [ 2 ]
Dehumanization is the denial of full ... plays in violence and genocide is far less significant than other factors such as obedience to authority and peer pressure. ...
An electrically operated water pump is the prime motivator in recirculating the water from the pool. Water is forced through a filter and then returned to the pool. Using a water pump by itself is often not sufficient to completely sanitize a pool. Commercial and public pool pumps usually run 24 hours a day for the entire operating season of ...
This type of pool cleaner pumps water out of the pool via its skimmer or drains, uses it for locomotion and debris suction, then returns it after being filtered via pool return or outlet valves. This is the least expensive and most popular type of cleaner, and it traces a random course around the pool.
Pressure regulator for domestic water supply. Outlet pressure is set with the blue handwheel and shown on the vertical scale. A water pressure regulating valve limits inflow by dynamically changing the valve opening so that when less pressure is on the outside, the valve opens up fully, and too much pressure on the outside causes the valve to shut.
The decline in public pool infrastructure has contributed to the privatization of swimming facilities, with many communities shifting to expensive membership-based pools or water parks for recreational swimming—widening the gap in access to swimming between high and low-income communities.
