The Pork King series are fully welded 304 stainless steel cased waterers built like a Sherman tanks so you can be sure that no amount of bumping and shoving by your hogs will hurt it. The umbrella style lift out cover makes service access easy and keeps out foreign material. Since sunlight can't get into the unit, there will be very little algae growth or calcium buildup. Pork Kings are insulated all over for heat retintion. The thermostatically controlled electric heaters in the Pork King series are very aggresive and no amount of winter weather will shut them down.
