Replacement Parts Describe Your Problem

Fixture leaks from the end of the spout

Typical Cause

Leaks are often caused by a scratched o-ring or grommet on the cartridge. On models that use a handle mechanism, a broken part could also be the cause.

Solution

1. Replace the cartridge (on one-handle models) or cartridges (on two-handle models). It is essential that the model of the unit be identified to ensure you are replacing the proper cartridge. Please view our Find Your Product section to determine your model and the cartridge(s) required. After determining the model, you can view step-by-step instructions in our Animated Installation Help section.
2. If the faucet uses a handle mechanism, inspect the parts. If one of these items is broken, the handle mechanism will need to be replaced. Please view our Find Your Product section to determine which handle mechanism your model uses.

Note: Improper installation of the handle mechanism can also cause this to occur. Kitchen faucet leaks at the bottom of the spout Typical Cause

On non-pullout or non-pulldown models, a scratched or torn o-ring or rubber seal not sealing properly inside of the spout can cause a leak. If this is a pullout or pulldown model, the vacuum breaker within the spout receptor may not be sealing properly.

Solution

For non-pullout or non-pulldown faucets:

This issue should be resolved by replacing the o-ring(s) 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 Moen service kit with the correct spout o-rings for your model, different models utilize different sizes of o-rings. Please view our Find Your Product section to determine your model. We recommend lubricating the spout o-rings with silicone-based grease (Moen part number 99915, included with o-ring kits). 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 spout to become difficult to operate. When replacing the o-rings, it is recommended that you clean the inside of the spout and the outside of the valve body.

For pullout or pulldown faucets:

1. Check the connection between the hose and the wand. There should be a screen washer or o-ring (depending on the model) that provides a seal between the two. If this is missing, or if it is compromised, then the screen washer or o-ring will need to be replaced. Please view our Find Your Product section to determine your faucet and the correct part or kit for that model.
2. If your model has a vacuum breaker, it may be leaking. This issue would be resolved by replacing the vacuum breaker or installing a vacuum breaker conversion kit inside of the spout receptor. This part will vary depending on the age and model of your faucet. Please view our Find Your Product section to determine your faucet and the correct part or kit for that model.

Side spray leaks when faucet is turned on Typical Cause Solution

The side sprayer would need to be replaced. It is imperative to identify your model because the side sprays are unique to certain models. To determine your model, please see our Find Your Product section. It is also recommended that you look underneath the sink to view the connection of the side spray hose to the discharge tube of the faucet. It is possible to have either a threaded connection (identified by a metal nut at the end of the hose) or our Hydrolock connection (a black piece with a white clip at the end of the hose) on the side sprayer hose. Make sure the correct connection type is obtained for your faucet.

Kitchen faucet leaks between the spout and the handle

Typical Cause

This type of leak is often caused by scratched or torn o-ring on the cartridge or spout.

Solution

First, it is essential to identify the model of your faucet. Please view our Find Your Product section to determine your model.

For non-pullout or non-pulldown faucets:

This issue should be resolved by replacing the o-ring(s) inside of the spout, as well as the cartridge. 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 Moen service kit with the correct spout o-rings for your model, and different models utilize different sizes of o-rings. When replacing the o-rings, clean the inside of the spout and the outside of the valve body. We also recommend lubricating the spout o-rings with silicone-based grease (Moen part number 99915, included with o-ring kits). 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 spout to become difficult to operate. Also, the correct cartridge will need to be identified and replaced.

For pullout or pulldown faucets:

Replacing the appropriate cartridge for your model of faucet should resolve the issue.

Low water flow from spout &mdash, 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 (Moen part number 100886) 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 &mdash, 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

1. Make sure both shut-off valves are fully turned on.
2. 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.
3. 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.

Low flow from side spray / Water still comes from spout with side spray activated Typical Cause

This is caused by a malfunctioning diverter or debris within the valve/spout.

Solution

Replace the diverter. Please view our Find Your Product section to determine your model and the required diverter. Also, make sure the valve body is cleaned. In some models, the diverter is installed in the valve body, on other models it is installed around the valve body under the spout. If it is one of these models, make sure the spout is cleaned as well.

If the side spray does not shut off completely, it would also need to be replaced.

Pulldown wand "falls" out of spout

Typical Cause

The hose weight is out of position, the docking collar is broken or the hose has yet to be calibrated.

Solution

1. Check the location of the hose weight. Some models will have white indicator mark on the hose. It is recommended the weight be installed between the start of the loop curvature and this mark. If your model does not have a white mark, then install the weight anywhere between 4" to 8" up from the start of the loop curvature. For optimal performance, maintain an 8"x8" clear area for the hose and weight to travel, free of any moveable items (bottles, cleaning supplies, etc.).

Note: The weight might need to be repositioned higher on the hose if non-moveable pipes or other fixtures are interfering with the hose or weight.

Inspect the docking collar. This will typically be a black plastic piece at the end of the spout where the wand should reside. If this is broken, it will need to be replaced. Please view our Find Your Product section to determine your model and the required docking collar.

If this is a new installation, the hose will need to be calibrated. This will occur after the hose has been filled with water and used for 24 hours.

Pullout or pulldown wand will not divert between "stream" and "spray" modes
