Delta Kitchen Faucet Leaking Under Handle: Causes and Solutions

Delta kitchen faucets are known for their durability and reliability, but sometimes they can develop leaks. One of the most common types of leaks is when water starts to drip under the handle. This can be frustrating and can lead to water damage if left unchecked. In this article, we will discuss the causes of this problem and how to fix it.

Causes of a Delta Kitchen Faucet Leaking Under Handle

Before we dive into the solutions, let’s first explore the possible causes of a Delta kitchen faucet leaking under the handle:

Worn Out O-ring

The O-ring is a small rubber ring that seals the faucet handle to the base. Over time, it can become worn out and cause water to leak out of the faucet. This is a common problem in older faucets that have been in use for several years.

Loose Handle

If the handle of your Delta kitchen faucet is loose, it can cause water to leak out from under it. This is because the handle is not tight enough to create a proper seal with the base.

Corroded Valve Seat

The valve seat is the part of the faucet that connects the spout to the base. If it becomes corroded, it can cause water to leak out from under the handle. This is a common problem in areas with hard water.

Solutions for a Delta Kitchen Faucet Leaking Under Handle

Now that we know the possible causes, let’s explore the solutions for a Delta kitchen faucet leaking under the handle:

Replace the O-ring

If the O-ring is the culprit, you can easily replace it. First, turn off the water supply to the faucet. Then, remove the handle by unscrewing the set screw. Next, remove the cap and unscrew the mounting screws. Finally, remove the old O-ring and replace it with a new one. Reassemble the faucet and turn on the water supply.

Tighten the Handle

If the handle is loose, you can tighten it using a screwdriver. First, remove the handle by unscrewing the set screw. Then, tighten the screw that holds the handle to the faucet base. Reassemble the faucet and turn on the water supply.
