CB Tech and Multipure Countertop to Undercounter Conversion Kit

This kit is designed to provide all the necessary parts to convert your CB Tech or Multipure Countertop (any stainless steel model) into an Undercounter Water Filter with a separate faucet (included).

  • CB Tech and Multipure Faucet Kit with preinstalled blue tubing
  • 4 Inlet and Outlet Quick Connect Fittings we include both sizes to fit all units (1/4" MNPT and 1/8" MNPT)
  • 1 Adapta Valve and Threading Adapter to connect to cold water supply
  • 4 ft. of Clear tubing
  • Wall mounting bracket and screws



  • Remove the hose fittings from the top of the unit.
  • Use the instructions for Below the Sink Installations found in the CB Series owner’s manual to complete the following:
  • Attach the Quick Connectors to the housing (page 8)
  • Install and mount the faucet assembly (page 9-13)
  • Connect the Adapta Valve to your cold water supply (page 14-15)
  • Push the clear tube from your cold water supply into the “In” port of the housing and the blue faucet tube into the “Out” port (page 16)
  • Locate the Multi-Pure unit under the sink in a convenient place. You can attach it to the wall with the small bracket enclosed, or you can stand it on the floor using the black acrylic sleeve (included with newer units only) (page 18).
  • Turn on the water supply using the Adapta Valve and open the faucet. Allow the water to run through the unit and faucet for a few minutes while you check for leaks (page 19).
  • If you do not have your owner’s manual, a copy can be obtained at this link: Owners Manual

Multipure Conversion Kit (Countertop to Undercounter)
Like others, we used this kit to convert our countertop multipure filter to hide under the sink counter. Ours is the older model with 1/8" fittings and we didn't notice the note to ask for them on the website because the product includes images of the smaller 1/8". So, when it says "different sizes available upon request", you would think that you only need to mention it if the picture looks different from what you need. Other than that issue, which was resolved by the vendor sending us the new fittings in the mail, the installation went very easily. All of the parts are top quality and super easy to put together. Really, anyone could do this conversion project; and the results are very nice - no more filter on the counter top! We have more space around the sink and the faucet hardware is a pleasure to look at and use. I highly recommend it! 4 stars for the mis-leading images for fittings, but 5 for the product itself. Cheers, Chris and Jackie

Exactly what we needed and when we realized that we had ordered the wrong fitting size, Best Filters sent us the correct fittings at no charge. Thanks, Best Filters!
