OMNIFilter’s BF56 Premium Heavy-duty whole house 20″ water filter system is designed to meet the high-flow and large capacity for the ranch, business, industry or larger homes with 1″ incoming water lines and is ideal for both well water and city water applications. Unique 1/4 turn by-pass cap allows you to change from filtered to non-filtered water allowing you to change cartridges without having to turn off the water to the whole house. This by-pass feature shortens the amount of time needed to change cartridges and reduces the mess that can come with typical cartridge changes. System easily attaches to any 1″ incoming water line to filter water for the whole house. A cartridge is not supplied with this system so you can customize it to your filtration requirements by using any number of OMNIFilter Heavy-duty cartridges. Choose the OMNIFilter RS6-20 cartridge to reduce sediment or the OMNIFilter TO8-20 to reduce taste and odors.
