Putting Plumbers Putty In Bathroom Sink Drain

Essential Aspects of Putting Plumbers Putty In Bathroom Sink Drain

Plumbers putty is a pliable, non-hardening sealant used to seal joints and connections in plumbing systems. When used properly, it can effectively prevent leaks and ensure a watertight seal. However, applying plumbers putty correctly requires careful attention to several essential aspects.

This comprehensive guide will delve into the key aspects of putting plumbers putty in bathroom sink drains, ensuring a successful and leak-free installation. We'll cover everything from choosing the right type of plumbers putty, preparing the drain surface, and applying the putty to prevent common mistakes and achieve a durable seal.

Choosing the Right Type of Plumbers Putty

The first step in putting plumbers putty in a bathroom sink drain is to choose the right type of putty. Different types of plumbers putty are available, each with varying composition and properties. The most common types include:

Oil-based: Oil-based plumbers putty is the most widely used type, known for its ease of application and flexibility. It is suitable for most sealing applications in sinks and drains.
Water-based: Water-based plumbers putty is a more environmentally friendly option, but it may not be as durable as oil-based putty. It is best suited for temporary seals or applications with limited water exposure.
Silicone-based: Silicone-based plumbers putty is a high-performance sealant that offers excellent adhesion and durability. It is primarily used for demanding applications, such as sealing gaps around shower drains or preventing leaks in high-pressure systems.

Preparing the Drain Surface

Before applying plumbers putty, it is crucial to prepare the drain surface to ensure a strong and lasting seal. Here are the steps to follow:

Clean the surface: Thoroughly clean the drain flange and the surrounding area with a degreaser or rubbing alcohol to remove any dirt, debris, or grease that may interfere with the adhesion of the putty.
Dry the surface: Allow the cleaned surface to dry completely before applying the putty. Any remaining moisture can weaken the seal and cause leaks.
Use a primer (optional): For added adhesion, consider applying a plumbing primer to the clean and dry drain surface. Primers help promote a stronger bond between the putty and the drain.

Applying Plumbers Putty

Once the drain surface is prepared, you can proceed with applying the plumbers putty. Follow these steps carefully:

Roll the putty: Create a rope-like roll of plumbers putty by rolling it between your fingers or a pair of pliers. The length and thickness of the roll should be sufficient to create a complete seal around the drain flange.
Position the putty: Place the rolled putty around the base of the drain flange, ensuring that it completely covers the flange's edge and extends slightly over the flange itself.
Press down the putty: Use your fingers or a putty knife to firmly press down on the putty, ensuring that it fills any gaps or unevenness around the drain flange. Avoid over-tightening or pushing the putty too deeply.
Smooth the putty: Use a damp cloth or sponge to smooth out the putty's surface, creating a clean and even seal.
Install the drain assembly: Carefully install the drain assembly over the sealed drain flange, being mindful not to disturb the putty. Tighten the drain assembly securely, but avoid over-tightening.
