Improve Your Kitchen Sink with a Drain Replacement You Can Do
Is your kitchen sink drain looking worse for wear? Does it seem clogged no matter how often you plunge it? Replacing an old and worn out drain is easier than you may think, and can quickly upgrade your kitchen's functionality.
With some basic tools and a few hours of time, even novice DIYers can install a new sink drain assembly. The result is a sink that drains smoothly, with less risk of leaks or backups. Read on to learn the steps for replacing your sink drain yourself.
Signs It's Time for a New Drain
There are a few clear indicators that your kitchen sink drain needs to be replaced:
- Visible corrosion around the drain basket or tailpiece
- Water pooling in the sink or leaking underneath
- Frequent clogs that are difficult to clear
- Strange gurgling noises coming from the drain
If you notice any of these issues, it likely means the inner seal is compromised and parts are wearing out. Replacing the entire assembly is the best solution.
Gathering Necessary Replacement Parts
Before starting the drain replacement process, you'll need to purchase the correct parts. Most kits come with a strainer basket, mounting ring, P-trap, and discharge tube. Here's how to find the right components:
First, measure from the sink drain outlet to the downward bend in the trap arm. Note the length and diameter. Then check your existing setup to see if it's a P-trap or S-trap design. With these details, you can find a kit with matching measurements and configuration.
Stainless steel, plastic, and cast iron are common drain material options. Plastic is affordable and easy to install. Cast iron and stainless steel are more durable choices that can reduce noise.
Tools for the Task
Changing out a sink drain requires just a few tools:
- Pipe wrench
- Hacksaw or pipe cutter
- Adjustable wrench
- Plumber's putty
- Bucket
- Rag
Having these basic items on hand will make the project go smoothly.
Removing the Old Drain
Once you have the new drain parts, it's time to take out the old assembly. Start by clearing under the sink and laying down some towels in case of drips.
Turn off the water supply lines and disconnect them from the faucet. Place a bucket under the sink to catch water still in the pipes. Unscrew the slip nuts holding the curved trap arm and horizontal tailpiece using a wrench or pliers.
Twist the mounting ring counterclockwise to release the drain basket. You may need to break the plumber's putty seal with a flathead screwdriver. Remove all the old pieces from underneath.
Adjusting the Drain Outlet Height
Check if your new sink depth requires lowering the drain outlet pipe in the wall. Deeper sinks may need this adjustment for proper fit and water flow. Cutting into the wall to alter the drain line is best left to a professional plumber.
Connecting the New Drain Assembly
Installation of the new drain is the reverse of removal. First, dry fit all the pipes to confirm they align correctly. Then apply plumber's putty around the drain basket flange and insert it into the sink opening.
Hand tighten the mounting ring over the putty seal. Attach the trap arm piece, followed by the tailpiece and P-trap with slip nuts. Make sure joints are tightened snugly but not overtightened.
Once assembled without leaks, reconnect the water lines to the faucet. Turn on the water and check underneath for any dripping. Finally, remove any excess plumber's putty and clean the sink area.
Added Improvements
While replacing the drain assembly, consider these additional upgrades for an improved kitchen sink:
- Installing a pop-up drain mechanism for easier cleaning
- Switching to a hands-free faucet for added convenience
- Using sound-absorbing drain parts to reduce noise
With the right materials and proper planning, you can tackle this DIY project and revitalize your kitchen setup in just an afternoon.
Know When to Call a Professional
Replacing a sink drain is very doable for a novice DIYer. However, if you encounter any of these issues, it may be best to call a professional plumber:
- Drain outlet pipe needs to be lowered or moved
- Rusty galvanized drain pipes that must be replaced
- No existing cleanout to access drain pipes
- Pipes that are misaligned or incorrectly sized
An experienced plumber has the proper tools and skills to adapt or modify more complex drain configurations.
Taking the time to replace an old and worn out sink drain has big benefits. You'll notice faster water drainage, fewer clogs, and less leakage under the sink. Your kitchen will look and work much better.
With a small investment of time and energy, you can make your kitchen shine again.
