Damaged O-rings

O-rings are not used by all faucet brands these days but still, some brands use them to keep faucet prices low. O-rings are made of plastic and it is used to create a water-tight seal.

When we turn the handle, the valve stem inside the faucet also turns and creates space for water to flow. With every turn, O-rings also move. With time, O-rings in the faucet wear out due to friction, heat, and air.

When O-rings wear out, it becomes difficult to turn the Moen faucet handle. It creates high friction so you need to use more power to turn the handle.

Rust and Corrosion

Every faucet at some point gets rusted. This is a common plumbing issue in many houses. Rust generally occurs in wet area. When metal that contains iron comes into contact with the air, rust formed over there.

When rust occurs inside the handle, the handle doesn’t move freely. It gets stuck due to rust particles and can’t move properly.

Mineral Buildups

Mineral buildups are only found in those areas that have hard water. Normal water doesn’t form any mineral buildup.

Mineral buildup forms slowly on the faucet. You can see buildup on the faucet spout but if it is being formed inside the faucet, you can’t see and with time it increases in the size. It starts blocking the way of the handle. People use water softeners to turn hard water into normal water.
