ToggleWhat is Plumber’s Putty?
Plumber’s putty is a soft, pliable sealing compound typically made from a blend of powdered clay and linseed oil or other types of oils. This combination gives the putty its unique properties: it’s flexible, easy to mold, and non-hardening, allowing for long-term use in sealing applications. Unlike other sealants such as silicone caulk, plumber’s putty remains soft and pliable, which makes it ideal for situations where a temporary or semi-permanent seal is required.
This compound is particularly well-suited for use in areas that are not exposed to pressurized water or where a waterproof seal is needed around non-porous materials like metal, ceramic, and plastic.
Common Uses of Plumber’s Putty
Plumber’s putty is primarily used in plumbing applications to create a watertight seal. Here are some of its most common uses:
1. Sealing Sink Drains and Fixtures
One of the most frequent uses of plumber’s putty is to seal sink drains and fixtures. When installing a new sink drain, plumber’s putty is applied around the lip of the drain flange before it is inserted into the sink. The putty creates a waterproof barrier that prevents leaks around the drain opening, ensuring that water flows smoothly down the pipes.
2. Installing Faucets
Plumber’s putty is often used when installing faucets to create a watertight seal between the base of the faucet and the sink surface. This prevents water from seeping under the faucet and causing damage to the countertop or cabinetry.
3. Sealing Basket Strainers
A basket strainer, commonly found in kitchen sinks, can be effectively sealed with plumber’s putty. The putty is applied to the underside of the strainer flange, providing a leak-proof seal between the strainer and the sink surface. This is essential to prevent water from leaking into the cabinet space below the sink.
4. Installing Shower Drains and Tub Drains
Shower and tub drains also benefit from plumber’s putty, which helps create a waterproof seal between the drain and the shower or tub surface. This ensures that water drains correctly and does not seep into the surrounding structure, potentially causing water damage over time.
5. Securing Plumbing Components
Plumber’s putty can be used to secure various plumbing components, such as sink sprayers and soap dispensers. It ensures a tight fit, preventing leaks and keeping the fixtures securely in place.
Advantages of Using Plumber’s Putty
There are several reasons why plumber’s putty is a preferred choice for many plumbing applications:
1. Easy to Use
One of the main advantages of plumber’s putty is its ease of use. It requires no special tools or equipment to apply, and its soft, pliable texture makes it easy to mold and shape to fit any application. This makes it an ideal choice for both professionals and DIYers alike.
2. Creates a Reliable Seal
Plumber’s putty is specifically designed to create a reliable, watertight seal around plumbing fixtures. Its non-hardening formula allows it to maintain its flexibility and conform to the surfaces it is applied to, ensuring a tight and effective seal.
3. Non-Hardening Properties
Unlike other sealants, plumber’s putty does not harden over time. This means that it can be easily removed if needed, making it an excellent choice for applications where adjustments or replacements may be required in the future.
4. Cost-Effective
Plumber’s putty is an affordable sealing solution compared to other products like silicone sealants. Its cost-effectiveness, combined with its reliability and ease of use, makes it a popular choice for a wide range of plumbing applications.
5. Versatility
Plumber’s putty can be used on a variety of materials, including metal, plastic, ceramic, and granite. This versatility allows it to be applied in numerous plumbing situations, from sealing sinks and drains to installing faucets and other fixtures.
How to Properly Apply Plumber’s Putty
To achieve the best results with plumber’s putty, it’s essential to apply it correctly. Here’s a step-by-step guide to help you:
Step 1: Clean the Surface
Before applying plumber’s putty, ensure that the surface where it will be applied is clean, dry, and free from any debris or old sealant. A clean surface is crucial for the putty to adhere properly and create a watertight seal.
Step 2: Prepare the Putty
Take a small amount of plumber’s putty from the container and roll it between your hands to form a long, thin rope. The thickness of the rope should be appropriate for the size of the fixture or drain you are sealing.
Step 3: Apply the Putty
Place the putty rope around the edge of the fixture, such as a drain or faucet base, where it will come into contact with the sink or countertop. Press the fixture firmly into place, allowing the putty to spread and create a tight seal.
Step 4: Remove Excess Putty
Once the fixture is in place, use a clean cloth or your fingers to remove any excess putty that may have squeezed out from the edges. Plumber’s putty does not harden, so this excess can be easily removed without damaging the seal.
Step 5: Tighten the Fixture
Tighten the fixture according to the manufacturer’s instructions. The plumber’s putty will compress and form a watertight seal between the fixture and the surface.
Step 6: Test for Leaks
After installation, test the fixture for leaks by running water through it. If you notice any leaks, you may need to reapply the putty or adjust the fixture to ensure a proper seal.
When Not to Use Plumber’s Putty
While plumber’s putty is a versatile sealing solution, there are certain situations where it may not be the best choice:
- Not Suitable for Porous Materials: Plumber’s putty is oil-based and can stain porous materials like granite or marble. In such cases, a silicone sealant or other non-staining sealant is recommended.
- Not Ideal for Pressurized Water Lines: Plumber’s putty is not designed for use in areas exposed to constant water pressure, such as pipe joints. For these applications, a pipe thread sealant or Teflon tape is a better choice.
- Avoid High-Temperature Applications: The oils in plumber’s putty can break down under high temperatures, so it’s not recommended for use in areas that will be exposed to high heat, such as certain parts of a kitchen or near hot water connections.
Conclusion
Plumber’s putty is an invaluable tool in the world of plumbing, offering a reliable, easy-to-use solution for creating watertight seals around fixtures and drains. Its versatility, affordability, and ease of use make it a popular choice for both professional plumbers and DIYers. However, it is crucial to understand its proper applications and limitations to ensure the best results. Whether you are installing a new sink, replacing a drain, or sealing a faucet, plumber’s putty is a must-have material that provides peace of mind and long-lasting performance.
