Kitchen faucet installation is a manageable home improvement task that can be completed by most homeowners with a moderate level of DIY experience. This guide provides step-by-step instructions for installing a Delta kitchen faucet, drawing from official installation manuals, supplementary installation guides, and general plumbing best practices. The information covers essential tools, installation techniques, and maintenance tips for the 21715LF and 21716LF models, both part of Delta’s Two-Handle Washerless Kitchen Faucet series.
Overview of Delta 21715LF and 21716LF Models
The 21715LF and 21716LF models are part of Delta’s Two-Handle Washerless Kitchen Faucet line. These faucets are designed for durability and ease of use, featuring a washerless mechanism that reduces the need for frequent repairs and maintenance. According to the manufacturer’s documentation, the installation process involves securing the faucet to the sink, connecting the water supply, and ensuring a watertight seal using appropriate gaskets or seals.
Delta’s official documentation emphasizes the importance of reading and following installation instructions carefully to avoid damage to the product or potential injury. The installation process includes several key steps: shutting off water supplies, removing the old faucet, installing the new faucet with its gasket, and securing the handle and spray support components. The user is also advised to use a silicone seal if the sink is uneven to ensure a secure and leak-free installation.
Essential Tools for Installation
Installing a Delta kitchen faucet requires a set of basic tools that are commonly available in most households or can be easily obtained from hardware stores. The following tools are essential for the installation process:
- Adjustable wrench: Used to tighten or loosen nuts and bolts during installation. This is a versatile and necessary tool for securing the faucet and connecting water lines.
- Basin wrench: A specialized tool designed to reach into tight spaces under the sink, allowing for the adjustment of mounting nuts. This is particularly useful in areas where a standard wrench may not fit.
- Screwdrivers (Phillips or flathead): Depending on the faucet model, you will need one or both types of screwdrivers to remove or secure screws.
- Plumber’s tape (Teflon tape): Used to create a watertight seal on threaded pipe connections. It is essential to wrap Teflon tape around the threads to prevent leaks.
- Plumber’s putty or silicone: These materials are used to create a watertight seal around the base of the faucet. The choice between putty and silicone depends on the faucet design and the manufacturer’s recommendations.
- Bucket or towel: Placed under the sink to collect any water that may drip during the installation process.
- Flashlight: Helps illuminate the installation area under the sink, which can often be dark and difficult to see.
Additional tools such as a utility knife may also be useful for removing old caulk or putty from around the base of the existing faucet before installation. Having these tools on hand ensures a smoother installation process and reduces the likelihood of interruptions or delays.
Step-by-Step Installation Process
The installation of a Delta kitchen faucet involves a series of well-defined steps. These steps should be followed carefully to ensure a successful and leak-free installation. Below is a detailed breakdown of the installation process:
Shut Off Water Supplies: Before beginning the installation, turn off the water supply to the kitchen. This is typically done by closing the shut-off valves located under the sink. If these valves are not accessible, it may be necessary to shut off the main water supply to the home.
Remove the Old Faucet: Using an adjustable wrench, loosen and remove the nuts that secure the old faucet to the sink. Carefully lift the old faucet out of the sink and set it aside. If the old faucet is sealed with caulk or putty, use a utility knife to carefully remove the seal before lifting the faucet.
Prepare the New Faucet: Place the gasket (included with the new faucet) at the bottom of the faucet. If the sink is uneven, apply a small amount of silicone under the gasket to ensure a secure fit. Insert the faucet through the mounting holes in the sink.
Secure the Faucet: Use the locknuts provided to secure the faucet to the sink. Tighten the nuts using an adjustable wrench, but be careful not to overtighten, as this can damage the gasket or the sink.
Install the Handles: Carefully install the handles on the faucet. The handle with the “H” mark should be placed on the left, and the handle with the “C” mark should be placed on the right. Before installing the handles, ensure that the glide ring is properly seated at the bottom of each handle.
Mount the Spray Support: If the faucet includes a spray feature, mount the spray support in the far-right hole of the sink. Insert the spray hose through the support and up through the center hole of the sink.
Connect the Water Supply: Attach the water supply lines to the faucet using Teflon tape on the threaded connections. Tighten the connections using an adjustable wrench.
Test for Leaks: Once the faucet is installed and all connections are secure, turn the water supply back on. Turn on the faucet and check for any leaks. If leaks are detected, turn off the water supply and reseal any connections as needed.
Final Adjustments: Make any necessary adjustments to the faucet handles or spray feature to ensure proper function and comfort.
Cleaning and Maintenance
Proper cleaning and maintenance are essential for ensuring the longevity and performance of the Delta kitchen faucet. The finish on the faucet is durable but can be damaged by harsh abrasives or polish. To clean the faucet, use a damp cloth to gently wipe the surface, then blot dry with a soft towel. Avoid using abrasive cleaners or scrubbing pads, as these can scratch the finish and reduce the faucet’s aesthetic appeal.
In addition to regular cleaning, it is important to inspect the faucet periodically for signs of wear or damage. If the faucet exhibits very low flow, it may be necessary to clean the aerator or remove and clean the seats and springs of any debris. Delta provides repair kits such as RP41850 and RP41702 for these types of maintenance tasks.
When to Seek Professional Help
While most homeowners can successfully install a Delta kitchen faucet on their own, there are situations in which it may be necessary to seek the assistance of a professional plumber. If the existing plumbing is outdated or damaged, or if the homeowner is unfamiliar with plumbing tools and techniques, it may be best to hire a licensed plumber to perform the installation. A professional plumber can also help identify and address any underlying plumbing issues that may affect the performance of the new faucet.
Conclusion
Delta kitchen faucet installation is a feasible project for most homeowners, provided they have the necessary tools and follow the manufacturer’s instructions carefully. The 21715LF and 21716LF models are designed for durability and ease of use, making them excellent choices for kitchen upgrades. By gathering the appropriate tools, preparing the installation area, and following the step-by-step process outlined in this guide, homeowners can successfully install a new Delta kitchen faucet and enjoy improved functionality and style in their kitchen.
As with any home improvement project, it is important to take necessary safety precautions and ensure that all connections are secure and leak-free. Regular maintenance and cleaning will also help prolong the life of the faucet and maintain its appearance. For those who prefer a hands-off approach or encounter complications during installation, hiring a licensed plumber is a viable option that can provide peace of mind and ensure a successful outcome.
