Need to replace the manifold/head assembly? We've got you! The manifold/head assembly is the main connection point on your system, housing the filter cartridges and tubing. Let's gets started on replacing it!
This article applies to models: BRDROS. If you have a Dual Filtration or Purifying system, please click here.

Disassemble the Unit
1. First, you'll want to start by turning the cold-water supply off to the system. Have a few towels nearby in case of any drips from leftover water in the hoses.
2. Go ahead and open/turn on the filtered water faucet. We need to allow the storage tank to empty completely. When the water stops running close/turn off the faucet. You can double check the tank is empty by lifting the tank – it'll be about 5 lbs.
3. Now, remove the green water supply hose from the manifold/head assembly by pushing IN on the green collet, and pulling OUT on the green hose.
4. Disconnect the yellow hose from the manifold in the same way. NOTE: This hose is attached to the pressurized tank, so a small amount of residual water may spray out when disconnected.
5. Remove the red hose from the manifold. Depending on your model, you may have a gray elbow at the red hose connection (pictured below). In this case, remove both the red hose and elbow. Confirm the flow control insert is inside the red hose (or gray elbow, if present):
6. Last hose to remove now is the blue one.
7. For the final step here, you'll need to remove your three filter cartridges. You can do this by twisting them counter-clockwise. Remove the Prefilter, then RO Cartridge/Membrane, then Postfilter. Then set the old manifold to the side.
Reassemble the Unit
1. It's important to make sure the end of your hoses don't have scratches or tears because this can cause leaks. Examine yours and then if needed, give the hoses a new square cut.
2. Go ahead and grab your new manifold and attach the hoses to the matching connection ports. Make sure to push the hoses in as far as possible to prevent leaking.
NOTE: Confirm the orange flow control insert is in the red hose (or elbow, if present) before reattaching the hose/elbow to the new manifold.
3. Once all your hoses are connected, you can now attach your previous filter cartridges (if under 6 months old), or new cartridges to the manifold. Start with the Postfilter, then RO Cartridge/Membrane, then Prefilter.
4. Now, you can turn the cold-water supply back on to the unit. Once it's turned on you'll want to watch for any leaking from the system or hoses.
Reminders
- After emptying the tank, it can take a few hours to fill back up again.
- If you've installed new filters, you'll need to Purge the system. Purging the system allows any loose activated carbon particles to be flushed from the new filters.
