If you're wondering whether or not you should put plumbers putty under your faucet, the answer is generally yes. Plumbers putty is a type of sealant that helps to create a watertight seal between your faucet and the sink. This is especially important if there is any gap or opening between the two surfaces.
Plumbers putty is made from a variety of different materials, but it is typically a soft, pliable substance that can be easily molded into place. Once it dries, it forms a strong, durable seal that will keep water from leaking through. It's important to note that plumbers putty should not be used on plastic or ceramic surfaces as it can damage these materials.
Applying plumbers putty is generally a pretty straightforward process. Start by cleaning both the faucet and the sink so that there is no dirt or debris present. Then, apply a small amount of putty to the underside of the faucet base and press it into place. Make sure to smooth out any air bubbles so that the sealant will lay flat against both surfaces.
Allow the plumbers putty to dry for at least 24 hours before using the faucet so that it has time to set properly. Once dry, your faucet should have a tight, watertight seal that will prevent leaks for years to come!
