Preserve and protect household plumbing and water-using appliances with the Culligan HD-950 heavy-duty sediment filter. Designed for installations where a 1-inch water main is present at the point of entry, this filter housing features a pressure relief button used at cartridge change time. For ease of cartridge change, a housing wrench is included. The large filter size provides extra capacity where high sediment concentration is an issue. Because water quality varies among locations, the HD-950 is sold without a filter cartridge. Learn More
