From traditional techniques to innovative new products, homeowners have various options to clear clogged sinks and keep their drains flowing smoothly. In this guide, we’ll walk you through eight time-tested and cutting-edge solutions for unclogging sinks so you can confidently tackle this pesky problem. This Old House plumbing and heating expert Richard Trethewey demonstrates several of these techniques and products in the video above.
Traditional Methods for Unclogging Sinks
These techniques have stood the test of time and can often resolve minor blockages quickly and easily.
Using a Plunger
A plunger is often the first line of defense against a clogged sink. This simple tool can be highly effective for dislodging minor blockages. Here’s how to use a plunger properly:
- Fill the sink with enough water to cover the plunger’s rubber cup.
- Place the plunger over the drain opening, ensuring a tight seal.
- Block the sink’s overflow opening with a wet rag to prevent air from escaping.
- Plunge vigorously up and down several times.
- Remove the plunger and check if the water drains.
Don’t forget to block the overflow opening. As Trethewey points out in the video, skipping this key step can result in water spraying back at you and making a mess.
Employing a Drain Snake
You can use a drain snake, or auger, to tackle more stubborn clogs. Follow these steps to use a drain snake:
- Insert the snake into the drain opening.
- Push it down as far as possible, then begin turning the handle.
- Continue feeding the snake while turning until you feel resistance.
- Rotate the snake to catch the clog, then slowly pull it back out.
- Clean off any debris and dispose of it properly.
While traditional drain snakes can be effective, you often have to remove the pop-up drain assembly to use them, which can be challenging for some homeowners. Many newer drain snakes are designed to fit underneath the pop-up, making them easier to use without disassembling the drain.
Innovative Solutions for Sink Clogs
As plumbing technology advances, new products and techniques have emerged to make unclogging sinks easier and more efficient.
Magnetic Pop-Up Drain Assemblies
One of the most innovative solutions Trethewey demonstrates in the video is a magnetic pop-up drain assembly. This clever design addresses several common issues with traditional pop-ups by doing the following:
- It allows for easy removal of the pop-up for cleaning or unclogging.
- It eliminates the rod that passes through the drain pipe, reducing a common clog point.
- It provides a clear pathway for water and debris to flow through.
The magnetic mechanism secures the pop-up in place when in use but enables quick removal when needed. This design reduces the likelihood of clogs while simplifying maintenance and cleaning.
Specialized Drain Cleaning Tools
Manufacturers have developed new tools to clear clogs without removing the pop-up assembly. These specialized tools—which are designed to navigate around the pop-up and reach deep into the drain—offer many advantageous features, including the following:
- An especially long reach to access clogs further down the pipe
- Barbed or hooked ends to catch and remove hair and debris
- Flexible, narrow designs that easily fit through drain openings
These tools are particularly effective for removing hair clogs, a common issue in bathroom sinks.
P-Traps With Integrated Cleanouts
Another innovative solution is the redesigned P-trap with an integrated cleanout. This updated version of the standard P-trap offers several benefits, including the following:
- It allows for easy snake insertion without disassembling the entire trap.
- It includes an additional access point for cleaning and unclogging.
- Some models feature a removable filter to catch debris before it causes a clog.
This design simplifies routine maintenance and clog removal, potentially reducing the need for professional plumbing services.
Advanced Techniques for Persistent Clogs
Traditional methods and newer tools might not completely clear stubborn clogs, especially if you have an older plumbing system. Advanced techniques such as the following can provide an extra push to restore your sink’s functionality.
Hydro-Jetting
Hydro-jetting uses high-pressure water streams to blast away persistent blockages within your plumbing system. This method is ideal if you need to remove grease, scale, and other stubborn debris that can cling to pipe walls. This technique typically requires professional equipment and expertise but can be highly effective for deep or extensive clogs.
Enzymatic Drain Cleaners
Unlike chemical drain cleaners that can be harsh on your pipes and the environment, enzymatic drain cleaners use natural enzymes to break down organic matter. These cleaners work more gradually to maintain clear drains and prevent future clogs. Regularly using enzymatic cleaners can keep your pipes in better condition over time.
Air-Burst Drain Cleaners
Air-burst drain cleaners use compressed air to create shock waves that dislodge clogs from pipes. These devices are useful for clogs caused by sand, food particles, or other solid materials. Available in multiple brands, air-burst cleaners are a powerful alternative to liquid or manual unclogging tools.
Preventive Measures for Sink Clogs
There are many effective tools and techniques for removing sink blockages, but preventing clogs is even better. Here are some preventive measures you can take to keep your drains flowing freely:
- Avoid pouring grease or oil down the drain, as these can solidify and cause blockages.
- Clean pop-up stoppers and drain openings regularly to remove accumulated debris.
- Install drain screens or strainers to catch hair and debris before they enter the pipe.
- Run hot water through the drain regularly to help dissolve and flush away soap scum and other buildup.
- Use enzymatic drain cleaners periodically to break down organic matter in the pipes.
