The Culligan® WH-HD200-C Heavy-Duty Sediment Filter Housing allows you to preserve and protect your household plumbing and water-using appliances. Designed for installations where a 1-inch water main is present at the point of entry, this filter housing features stainless steel reinforced inlet/outlet and cap for added durability. A filter life indicator is built into the filter head which alerts you when you need to change your filter cartridge . The large filter size provides 4 times the capacity where high sediment concentration is an issue. Because water quality varies among locations, the WH-HD200-C is sold without a filter cartridge. The unit comes with a 2-year limited warranty. The WH-HD200-C housing uses filter cartridges CW5-BBS, CW25-BBS, CP5-BBS, P25-BBS, R50-BBSA, and RFC-BBSA. Filter cartridge sold seperately.
