Causes of Moen Faucet Leaks at the Base

Before we dive into the solutions, let’s first take a look at what causes Moen faucet leaks at the base. Here are some of the most common causes:

Loose Connections

If the connections between the faucet and the sink are loose, water can seep through and leak at the base. This is often caused by wear and tear over time or improper installation.

Worn Out O-Ring

The O-ring is a small rubber ring that helps create a tight seal between the faucet and the sink. If the O-ring becomes worn out or damaged, it can cause leaks at the base.

Corroded Valve Seat

The valve seat is the part of the faucet that connects to the spout. If it becomes corroded, it can cause leaks at the base. This is often caused by hard water or mineral buildup.

Cracked Cartridge

The cartridge is the part of the faucet that controls the flow of water. If it becomes cracked or damaged, it can cause leaks at the base.
