Vicki, as a military wife, spent years completing home projects when her husband was deployed. Many homes have been great teachers.
- When purchasing a home one of the things to look for are good records and instructions. Often this doesn’t happen. Unfortunately, if someone has remodeled and used faucets, shower heads or appliances without any product name displayed, it is hard to maintain and repair.
- When there is problem, and there always will be, the best results will come from watching videos that are for products like what you want to work on. You’ll need basic tools and home repair knowledge.
- When a waterfall facet is not working properly, first identify the problem making sure the water shut-off valves under the sink are closed. In this case, the flow from one tap was slow and the second sink had a faucet where the flow had stopped completely.
- Make sure to turn off the water flow to the facets before begining your work. (Make sure the handles of the shut off valves under the sink are turned completely to the right as tight as you can get them without stripping or breaking them).
- In the case of this facet, the initial removal screw was behind the Hot/Cold (color plastic) indicator which was found through trial and error. Use a flat head screwdriver to pop it out. Be sure to close the drain first to avoiding losing any small parts.
See picture below
Begin the Process
Remove the Hot/Cold Handle
Behind the hot/cold cover you will find a small opening and if you look into the opening, there will be a small screw. It is difficult to see the screw, but if you insert an Allan Wrench, it will fit into the screw. (turn left to loosen). Using the Allan wrench, turn it carefully and extract the screw and carefully lay it to the side.

Disassemble the Faucet
Once the screw is removed, the handle will easily lift off.
- Under the handle you will see a protective collar which will simply pop up when you use a strong knife blade to get into the bottom crevice.
- With a sharp edge, lift the ring up that the handle was resting on.
- Take channel locks and gently screw off the collar. Depending on the assembly, putting a cloth or a thick rubber band on the metal may protect from scratches.
- Then the plastic mechanism is exposed. Grab the control knob to lift the plastic mechanism out. If it is too tight, it can be lifted out with a needle nose plier. Be sure the control arm is in the neutral position. (straight up)
- The interior is exposed and it is made up of two pieces. Once you take these two pieces apart the restrictor will be revealed. You will also find in addition to the restrictor which is plastic, a screen that filters pollutants, and two openings, one for cold water and one for hot water.
Expose Interior Body
- With the Hex head collar removed, lift the plastic control mechanism out of the faucet body. Be sure the control arm on top is kept straight up.
- The interior of the faucet body is not exposed.
- There is what you should see: 2 shallow indentations drilled into the metal body.
- 1 large hole with a plastic plug in it. It may be blue or green with slits all around it. This is the water flow restrictor.
- There is a two-part assembly which will have to be separated to expose the restrictor and the screen. The screen could be a component of the problem.
- Very gently separate the parts. They are joined with plastic clips and caution will have to be taken not to break the clips.

Removing the Restrictor
It seems from research that most, if not all, waterfall faucets have a restrictor. Low water flow, may be resolved from removing this plastic device.
- If you have a hard time removing this, you can take a drill and sheet rock screw and drill through the restrictor and pull it out in that manner.
- Replace the interior handle mechanism. If when you turn the water back on and move the control to hot or cold, you still do not have an adequate flow of water the issue may mean that the filter screen needs to be clean.
- See pictures below.
Removing the Restrictor
Exposing the Screen
- Next step is to clean the screen
- The screen is next to the area where the restrictor was removed. This is where the hot/cold flow areas are also. There is nothing to be done to the hot/cold flow.
- You will see a very small screen. On first view the screen may look fine, but clean with detergent and an old toothbrush and the screen will be transparent.

Now it is time to check and see if you have solved the problem.
- The two-piece plastic assembly should be rejoined.
- Remember to turn the water flow back on under the sink for this test.
- Set the assembly back in its housing. Using the control lever turn the faucet on. Make sure you test the hot side, cold side and middle.
- The flow should be much better than before, although waterfall faucets were designed to limit water consumption. If the flow was not existent or had a very limited flow, the improvement will be instantly noticeable.
- If problem solved, again closed the drain so no parts are lost.
- Now you can complete reassembling the faucet in reverse order.
