  • Watts W20FFPH1CBPR #20 Big Clear Whole House Water Filter Housing:
  • The #20 Big Clear housing is a large capacity housing suitable for high flow applications.
  • The extra large housing allows for greater water filter cartridge capacity, reducing the number of vessels required for high flow-rate applications.
  • The #20 Big Clear Housing will meet all of your large-capacity filtration needs, including high-flow and heavy-sediment applications.
  • Big Clear Filter Housings offer on-site examination of flow, performance, and cartridge life and are ideal for a variety of applications.
  • The polypropylene caps include a pressure-relief button on the inlet side to relieve pressure inside the housing when changing water filter cartridges.
  • Durable construction
  • Whole House housings extend the life of washing machines, water heaters, and other household appliances.
  • Ideal for homes, farms, private wells, restaurants, swimming pools, spas, and trickle irrigation.
  • 1" inlet/outlet for high-flow and heavy-sediment capabilities with minimal pressure drop
  • Leaking is prevented by the dynamically sealing O-Ring. The O-Ring should be replaced periodically to prevent leaks.
  • The water filter cartridge is not included with the housing. This allows you to purchase the best water filter for your water supply.
  • #20 Big Clear Whole House Housing Tips:
  • For many applications, it makes sense to install two whole house housings. The first housing is for sediment reduction. The second housing is for the carbon filter to improve taste and odor and reduce additional contaminants. By installing the sediment filter first, the carbon filter will last longer because it does not get clogged with sediment. Since carbon filters are more expensive, it is better to have the sediment filter first that needs to be replaced more often. If you install two whole house housings, there is a double mounting bracket available for installation of two housings.
  • If you have a lot of sediment in your water, you may want to consider three housings. The first two housings are for sediment reduction. The first housing contains a higher micron sediment filter and the second housing contains a lower micron sediment filter. The third housing is for the carbon taste and odor water filter. An example application is the first housing containing a DGD-7525-20 filter, the 2nd housing containing a DGD-5005-20 filter, and the 3rd housing containg a carbon filter such as the GAC-20BB. If you install three whole house housings, there is a triple mounting bracket available for installation of three housings.
  • Connecting two #20 Big Clear Housings:
  • Two #20 Big Clear housings can be connected with a pipe nipple or pipe union. There are several pipe nipples available that can be used to connect two #20 Big Clear Housings. See all combinations of pipe nipple options here.

  • #20 Big Clear Whole House Replacement Water Filter Information:
  • The water filter cartridge is not included with the housing. This allows you to purchase the best water filter for your water supply.
  • The water filter cartridge life depends on the water filter cartridge purchased, the quality of your water, and the amount of water used. You will know when to change the filter cartridge when your water pressure drops.
  • Sediment water filters reduce dirt, sand, silt, sediment, rust particles, and scale particles. Choose from one of our sediment water filters at the 20" x 4.5" Big Blue Filter Page.
