Low water flow from spout — BOTH hot and cold water on sink faucets
Typical Cause

Depending on the model, this could be caused by debris in the cartridge, debris in the aerator, a stuck diverter or a malfunctioning wand.

Solution
First, it is essential to identify the model of your faucet. Please view our Find Your Product section to determine your model. Also, it is recommended that the supply lines from the shut-off valves be checked to ensure the faucet is receiving full pressure from both hot and cold supply lines.

For pullout or pulldown kitchen sink faucets:
Remove the hose from the wand and inspect the screen that is in between these items. If there is debris in the screen, rinse it off with water. Then, hold the end of the hose in the sink and turn on the water. If the pressure is good from the hose, reinstall the screen and wand. This should resolve the issue. If there is still low pressure after reinstalling the wand, then the wand would need to be replaced. If there is low water pressure from the hose, the cartridge would need to be replaced and the valve body would need to be flushed and cleaned.

For non-pullout or non-pulldown kitchen sink faucets:
Remove the aerator and rinse off any debris. If this does not resolve the issue, and if the unit also has a side spray, check the pressure from the side spray. If the side spray has good pressure, then try activating the trigger on the side spray several times to see if pressure returns to the spout. If it does not, then the diverter would need replaced. If your model uses a hardware kit with a diverter, then it is recommended that the hardware kit be replaced in addition to the diverter. If this does not resolve the issue (or if your faucet does not have a side sprayer), the cartridge would need to be replaced and the valve body would need to be flushed and cleaned.

For bathroom sink faucets:
Remove the aerator and rinse off any debris. If this does not resolve the issue, then the cartridge (for one-handle faucets) or cartridges (for two-handle faucets) would need to be replaced and the valve body would need to be flushed and cleaned.


Low water flow from spout — ONLY hot or cold water on sink faucets
Typical Cause

This is caused by the shut off valves not being turned on, a lack of pressure through one of the shut off valves or an obstruction in one of the supply lines feeding water to the faucet.

Solution
Make sure both shut-off valves are fully turned on.
Check both the supply lines from the shut-off valves to the faucet. These supply lines need to deliver full pressure to the faucet. If the supply lines do not deliver full pressure, then the faucet will not produce full pressure. The plumbing of the home would need to be investigated for a resolution.
If the issue is still not resolved, then the cartridge (for one-handle faucets) or cartridges (for two-handle faucets) would need to be removed (or replaced) and the valve body would need to be flushed and cleaned.


Spout is difficult to rotate
Typical Cause

This is caused by debris and/or an impaired o-ring inside of the spout.

Solution
For non-pull out or non-pull down faucets:

Remove the spout and lubricate the spout o-rings with silicone-based grease. Do not use plumber's grade faucet grease, silicon sprays or any lubricant that may contain petroleum. Petroleum-based lubricants may react with the rubber seals and cause the spout to become even more difficult to operate. It is also recommended that you clean the inside of the spout and the outside of the valve body when replacing the o-rings.
Replace the o-rings inside of the spout. The number of o-rings inside of your spout will vary depending on the model. It is essential to identify the model of the faucet in order to obtain the proper Rbrohant service kit with the correct spout o-rings for your model; and different models utilize different sizes of o-rings. Remember to clean the inside of the spout and the outside of the valve body when replacing the o-rings, as well as lubricating the o-rings with silicone-based grease.
Inspect the retainer nut on top of the spout (if applicable). Make sure it is not overly tightened.
Note: If the mounting nut underneath the sink is overly tightened to the mounting bracket, this could cause the spout to be difficult to rotate.

For pullout or pulldown faucets:
Remove the spout receptor and clean any debris that is impeding the movement.
If there is corrosion on the valve body of the interior of the spout receptor, the faucet will need to be replaced.
Note: If the mounting nut underneath the sink is overly tightened to the mounting bracket, this could cause the spout receptor to be difficult to rotate.


Handle is difficult to operate
Typical Cause

This is usually caused by (but not limited to) sediment or debris in the cartridge, mineral buildup or a damaged seal within the cartridge. If the handle is loose it may not be installed properly or there may be an issue with the handle mechanism.

Solution
The cartridge will need to be serviced or replaced.
For faucets need to serviced, simply remove the cartridge and lubricate it both inside and out with a silicone-based grease. Do not use plumber's grade faucet grease, silicon sprays or any lubricant that may contain petroleum. Petroleum-based lubricants may react with the rubber seals and could cause the handle to become even more difficult to operate.


Handle will not stay in the on position (one-handle faucets)
Typical Cause

During manufacturing, lubrication (silicone) is used on the cartridge. The combination of lubrication and the weight of the handle can cause the faucet to self-close. For models using a handle connector, a metal washer may be missing or the connector could be broken.

Solution
First, it is essential to identify the model of your faucet.
Try to make sure all the screws are tight, tighten the cartridge nut or replace the cartridge.
If your faucet has a handle connector:
Change the handle connector.
If the cartridge was replaced, check the old cartridge stem for a gray metal washer. This washer must be transferred to the stem of the new cartridge.


Pop-up drain assembly not closing or opening properly
Typical Cause

This is caused by either a broken pivot rod or an issue with the adjustment the pivot rod or lift rod.

Solution
Inspect the pivot rod. This will be a silver rod that should be installed into the rear of the drain. Depending on the model, there will be a metal or gray plastic pivot rod nut securing the rod in place. This nut can be unscrewed to view the pivot rod. If this rod is broken, it will need to be replaced.
If the pivot rod is not broken, then it will need to be adjusted in conjunction with the lift rod. With the lift rod (the rod that you pull up on the close the drain) in position, verify it is inserted into the lift rod strap (this is a metallic piece with a series of holes) and secure it with the lift rod strap screw.
Connect the pivot rod to the lift rod strap using the spring clip that should be on the pivot rod.
Place the drain plug in the full open position, then loosen the lift rod strap screw and adjust the lift rod height so that the knob on top of the lift rod clears the faucet. Then tighten the lift rod strap screw.


Note: The installation instructions for your faucet will illustrate on how to do this. If you no longer have the installation instructions, please view our Find Your Product section to determine your model. This will allow you to view or download the installation instructions.
