Water Coming Out of Bathroom Faucet Handle: Causes and Solutions

A bathroom faucet leaking from the handle is a common plumbing issue that can be frustrating and wasteful. The leak can be caused by a variety of factors, from worn-out washers and O-rings to a faulty cartridge. Understanding the source of the leak is crucial to effectively addressing it. This article will guide you through the common causes of water leaking from the faucet handle and provide solutions to fix the problem.

Worn-Out Washers and O-rings

The most frequent cause of a leaking faucet handle is worn-out washers and O-rings. These small rubber components, located within the faucet stem, are responsible for creating a seal that prevents water from flowing when the faucet is turned off. Over time, these washers and O-rings can become worn, cracked, or brittle, leading to leaks. When the handle is turned, the pressure of the water pushes past the worn-out seal, causing water to escape from the handle.

To fix this issue, the worn-out washers and O-rings need to be replaced. This typically involves dismantling the faucet handle and removing the worn-out parts. New washers and O-rings can be easily purchased at most hardware stores. The specific size and type of replacement parts will depend on the model of your faucet.

Faulty Cartridge

For faucets with a cartridge, the culprit behind a leak might be a faulty cartridge. Cartridges are the primary control mechanism in many modern faucets. They contain a ceramic disc that controls the flow of water. When the cartridge wears down or becomes damaged, it can allow water to leak through the handle. This is particularly common in faucets that have been subjected to hard water, which can cause mineral buildup that damages the cartridge.

The solution for a faulty cartridge is to replace it. Replacing the cartridge involves removing the handle and replacing the faulty cartridge with a new one. It is important to select a cartridge compatible with your faucet's model.

Loose or Damaged Stem Nut

Another potential reason for a leaking faucet handle could be a loose or damaged stem nut. The stem nut is located within the faucet body and acts as a locking mechanism for the faucet stem. If the stem nut is loose, it can allow the stem to move, leading to a leak. Moreover, a damaged stem nut might not be able to adequately secure the stem, resulting in water escaping from the handle.

Tightening the stem nut is often the solution for a loose stem nut. However, if the stem nut is damaged, it needs to be replaced. To access the stem nut, the handle must be removed. You may need to use a wrench to tighten or replace the stem nut.

Corrosion or Mineral Buildup

Corrosion or mineral buildup within the faucet can also lead to leaks from the handle. Hard water can leave mineral deposits that obstruct the faucet's internal mechanisms. It can also cause corrosion, leading to wear and tear on the faucet's components, which can create leaks.

Addressing corrosion and mineral buildup requires cleaning the faucet's internal parts. This might involve disassembling the faucet and soaking the parts in vinegar or a commercial descaling solution. You may also need to replace components that are heavily corroded or damaged.

It's crucial to note that repairing a leaking faucet handle can be a complex task, and some situations might necessitate professional assistance. If you lack the necessary experience or feel unsure, seeking help from a qualified plumber is recommended.
