No matter how good a shower head is, it can leak or drip at some point. If your Moen shower head is leaking and you are wondering what to do about it, you are at the right place.
General Reasons Your Moen Shower Head may Leak [Solutions Included]
Worn-Out Cartridge
The cartridge inside your Moen shower head is a critical component that controls water flow and temperature. Over time, the cartridge can wear out due to constant use and mineral buildup, leading to leaks. This is particularly true if the shower head has been in use for many years or if the water supply is hard, which accelerates wear and tear.
Solution: Replacing the cartridge is the most effective way to address this issue. Turn off the water supply, remove the shower handle and the trim plate, and replace the old cartridge with a new one. Ensure that the replacement cartridge is the correct model for your shower head.
Loose Connections
Another common cause of leaks in Moen shower heads is loose connections. These can occur at various points in the shower assembly, such as where the shower head connects to the arm or where the arm connects to the wall. Loose connections can result from improper installation, regular wear, or slight shifts in the plumbing over time.
Solution: Tighten any loose connections. This usually requires an adjustable wrench or pliers. Remember to be gentle to avoid damaging the connections. If the leak persists, applying the plumber’s tape to the threads before re-tightening can help create a watertight seal.
Damaged Seals or O-Rings
Seals and O-rings are small but crucial components that help prevent leaks by creating tight seals at connection points. Over time, these can become brittle, crack, or degrade, especially in areas with hard water. When these components fail, water can escape, leading to leaks.
Solution: Replace the damaged seals or O-rings. This often involves disassembling part of the shower head to access and replace these small parts. It’s important to use seals or O-rings designed for your specific model of Moen shower head to ensure a proper fit.
Mineral Buildup
In areas with hard water, mineral deposits can build up inside the shower head and on other components, like the cartridge or the valves. This buildup can obstruct water flow and force water to escape through small gaps or weak points, resulting in leaks.
Solution: Regular cleaning to remove mineral buildup is key. Detach the shower head and soak it in a vinegar solution, or use a commercial descaling product. For internal components, such as the cartridge, removing and cleaning or replacing them can resolve the issue.
Faulty Valve Body
The valve body is the central part of your shower’s plumbing that controls water flow and temperature. A cracked, corroded, or otherwise damaged valve body can lead to persistent leaks, as it may no longer be able to properly regulate water flow.
Solution: Repairing or replacing a faulty valve body is a more complex and might require professional assistance. If you choose to do it yourself, turn off the water supply, disassemble the shower unit to access the valve body, and replace it with a new one, ensuring compatibility with your shower system.
Moen Shower Head Leaking with a Standard Valve
Continuous Leaking
- Reason: Continuous leaking occurs when the shower system keeps running or dripping with the handle in the off position.
- Solution: Replace the 1225/1200 cartridge. This is a common fix for the standard valve system, which uses a push/pull handle.
Water Leaks from Handle
- Reason: This is typically due to issues with the internal components of the shower system.
- Solution: Replacing the 1225/1200 cartridge should resolve this issue.
Showerhead Leaks When Running the Tub Spout Only
- Reason: This symptom, known as stacking, occurs due to specific flow dynamics in the plumbing.
- Solution: To solve the issue of stacking in a shower system, it typically involves adjusting the plumbing to ensure proper water flow dynamics. This might include modifying how the tub spout and showerhead are connected to the water supply to prevent water from leaking out of the showerhead when the tub spout is in use. For specific instructions or more complex cases, it is recommended to consult a plumbing professional or refer to the manufacturer’s guidelines.
Moen Shower Head Leaking with an M-Core Valve
Continuous Leaking with the Handle in the Off Position or Water Leaks from Handle
- Reason: This is usually due to issues with the flow cartridge.
- Solution: The flow cartridge should be replaced. The specific cartridge number depends on the M-Core Valve series.
Water Leaks Around the Escutcheon/Back Plate
- Reason: This can occur in new installations if the cartridge nut is not tight enough or the cartridge parts are not correctly assembled.
- Solution: Tighten the cartridge nut and confirm the correct assembly of the cartridge parts. Replace the flow cartridge if necessary.
