Understanding Your Delta Kitchen Faucet

Delta faucets are renowned for their durability, innovative designs, and advanced features. However, like any mechanical device, they’re susceptible to wear and tear over time.

Knowing the specific model and its internal workings is the first step in diagnosing and fixing any issues.
