How to Unscrew a Drain Cover: The Ultimate Guide for Homeowners
As a home improvement expert with over 15 years of experience renovating bathrooms and upgrading drains, I‘m often asked how to properly unscrew and remove a drain cover. It may seem like a simple task, but doing it correctly ensures your drains stay clear and prevent costly plumbing issues down the road.
In this comprehensive guide, I‘ll walk you through the entire process step-by-step, from the right tools to use to cleaning and reinstalling covers. You‘ll learn insider tips and tricks for dealing with stuck covers and avoiding beginner mistakes.
Knowing how to maintain your drains is an invaluable DIY skill for any homeowner. After reading this, you‘ll be able to quickly tackle removing drain covers with confidence. So let‘s get started!
Why Learn This Skill?
Before we dive in, let me quickly explain why learning how to unscrew and remove drain covers is so useful:
-
Prevent clogs – Removing the cover allows you to thoroughly clean the drain pipes and stop debris from accumulating. A clean drain equals better water flow.
-
Inspect for damage – Taking the cover off lets you check the drain pipes and connections for any cracks or issues needing repair. Catching problems early is key!
-
Improved hygiene – Taking drain covers off helps remove mold, mildew and bacteria that can build up out of sight. This improves sanitation.
-
Save money – Doing this simple maintenance yourself avoids the high hourly cost of a plumber. My hourly rate is $75 – that adds up quickly!
-
Enhances safety – Loose, damaged or missing covers can cut feet and allow objects to fall into the drain – removing them allows you to fix any issues.
-
Increase home value – Properly functioning drains keep your home working properly and in good shape if you ever want to sell.
Now that you know why this is an important skill, let‘s look at the basic tools you‘ll need.
Must-Have Tools
One of the first questions I always get from homeowners is "What tools will I need to remove my drain cover?"
While you likely have these basic tools already, here are the essentials I recommend having on hand before starting:
| Tool | Purpose |
|---|---|
| Screwdrivers | A Phillips head and standard flathead screwdriver in various sizes to loosen cover screws |
| Pliers | Preferably needle-nose and channel-lock pliers to grip covers and screws |
| Putty knife | For prying up stubborn covers sealed with putty |
| Penetrating oil | Such as WD-40 to loosen stuck screws and bolts |
| Gloves | Protect hands and improve grip when removing dirty covers |
| Safety goggles | Shield eyes from debris and grime while working |
I also suggest having spare screws, a wire scrub brush, and silicone caulk or plumber‘s putty on hand for reinstalling the cleaned cover.
Optional extras like a drain snake, hammer, and rag are handy too. Equipped with these supplies, you‘ll be fully prepped for the task!
Types of Drain Covers
Now that you‘ve gathered your toolkit, let‘s go over the main types of drain covers you might encounter so you know what to expect:
Grate Covers
The most common, grate covers (also called drain grates or drain grilles) allow water to pass through small slots or openings while capturing larger debris.
Grate covers are usually made from materials like:
- Plastic
- Galvanized steel
- Cast iron
- Bronze
They can be found on sink, tub, floor, and outdoor drains. Most grate covers are removable by unscrewing.
Dome Covers
Dome covers feature a rounded, shallow bowl shape that sits over floor drains. Their smooth, sloped design prevents debris from getting lodged while allowing water to easily drain off.
Dome covers are common in basements, garages, patios, and commercial settings. The dome‘s low profile makes it safer for foot traffic.
Trench Drain Covers
Trench drains contain long, narrow openings that are designed to rapidly channel away water. Their linear covers come in different lengths and particulate-blocking capacities.
These covers are essential components of trench drains, which are often installed on slopes or next to foundations to prevent flooding and erosion issues.
Recessed/Square Covers
As the name implies, recessed or square covers sit flush within the floor or shower base. Once secured, they are mostly invisible.
Recessed covers are used when an inconspicuous, seamless look is desirable such as in modern bathrooms and showers.
Decorative Covers
For certain aesthetic sensibilities, decorative drain covers crafted from materials like marble, stone, or cast iron can provide an upscale, stylish look.
However, these artistic covers should not be subject to heavy loads or traffic. Use them only in appropriate lower impact areas to prevent cracking.
Now that you know the main drain cover categories, let‘s get down to actually removing them.
Step-by-Step Removal Process
While drain covers vary, the method for taking them off is generally straightforward. Just follow these steps:
1. Clear Debris
Before attempting to unscrew the cover, wipe away any dirt, hair, leaves or other debris that has collected around it using a paper towel or small brush. This allows you to access the cover and hardware.
2. Locate Screws
Most drain covers will have visible screws that hold them in place. For square or recessed covers, you may need to peek over the edges to find the screws.
Covers that don‘t have screws likely have a pressure fit rim or snap into special slots. We‘ll go over removing those types later.
3. Loosen Screws
Using your screwdriver, turn each screw 2-3 rotations counterclockwise to loosen it. Take care not to strip the screws by applying too much torque.
If they won‘t budge, try applying some penetrating oil and letting it sit for 15 minutes before attempting to loosen them again.
4. Lift Off Cover
Once all the screws are loose, you can gently lift the cover straight up to remove it, being cautious not to let any screws drop down into the drain.
Pry up covers that remain stuck with a flathead screwdriver or putty knife. Wiggle it from side to side to break the seal.
5. Clean Cover and Drain
Give the cover a thorough scrubbing with a stainless steel cleaner or scrubbing pad to remove all grease and grime before putting it back on.
Use a wire brush, drain snake or chemical cleaner to clear any debris or buildup from the exposed drain pipes as well.
6. Inspect and Replace
Check the removed cover for any cracks, rust or other damage. If it‘s intact, you can reinstall it. If not, measure the drain dimensions and purchase an identical replacement.
7. Reattach Cover
Place the cleaned cover back over the drain opening. Hand tighten the screws evenly until snug. Avoid overtightening. Ensure the cover sits flat without rocking. Add plumber‘s putty if needed.
And that‘s it – following those 7 steps will allow you to successfully remove and replace most screw-mounted drain covers. Next I‘ll go over some pro tips for extra stubborn covers.
Pro Tips for Stubborn Covers
Over years of tackling home drain issues, I‘ve encountered some very stubborn covers that refused to budge when unscrewing.
Here are my best pro tips for freeing stuck-on drain covers:
Soak with Penetrating Oil
Spray penetrating oils like WD-40 or PB Blaster liberally around the edges and screw heads. Allow it to soak 15-20 minutes before trying again. This can help loosen rust and mineral deposits.
Apply Targeted Heat
A quick spritz of heat from a hairdryer or heat gun around the stuck areas helps expand and break down any grime or corrosion. Just don‘t overdo it and melt plastic components.
Slice Caulk Seal
Covers with a thick caulk seal can be freed by first running a utility knife around the perimeter to break the grip of the caulk. Go slowly and keep the blade flat when slicing.
Give It a Few Whacks
Place a small block of scrap wood on top of the cover and firmly tap it with a hammer. The vibration can help shake loose a stubborn cover.
Replace Stripped Screws
If screws just endlessly spin in place, use pliers or a Dremel to cut them out. Replace with slightly larger screws for a fresh grip.
With a little perseverance and these tips, you can conquer even the most unwilling drain covers!
Safety Precautions
When dealing with drains, especially cleaning products, be sure to take these basic safety precautions:
-
Wear closed-toe shoes and gloves to protect skin from gunk and chemicals.
-
Put on safety goggles to keep debris from getting in your eyes while scrubbing.
-
Avoid using harsh chemical drain cleaners. Opt for natural cleaners when possible.
-
Keep tools away from the drain opening so screws or other items don‘t disappear down the drain!
-
Never blindly stick your fingers down the drain – there could be sharp debris or you could get stuck.
-
Clear trip hazards and work carefully to avoid falls around slippery, wet drains.
Staying safe takes just a little common sense. Now let‘s look at reinstalling drain covers.
Reattaching the Drain Cover
Once you‘ve cleaned the cover and drain, putting everything back together is a cinch. Just follow these steps:
1. Apply New Plumber‘s Putty
If your drain requires a sealant, apply fresh plumber‘s putty or silicone caulk around the lip before replacing the cover.
2. Align and Lower Cover
Carefully lower the cleaned cover back into place, aligning any screw holes or notches. Ensure it sits flat.
3. Tighten Screws
Evenly tighten down the screws to secure the cover back in place, being careful not to overtighten. Snug is sufficient.
4. Remove Excess Putty
Wipe away any excess plumber‘s putty or caulk to leave a clean, watertight seal around the edges once dry.
And that‘s all there is to it – just reverting the steps you took to remove the drain cover will allow you to safely reinstall it.
Answering Common Questions
Over the years, I‘ve been asked just about every question imaginable about dealing with drain covers. Here are some of the most frequent ones:
How can I get my shower drain cover off without tools?
Many shower drain covers have small slots you can insert fingers into and grip to pry up and remove them. Just be very careful not to bend or crack the cover.
What should I do if the screws are so rusty they break?
First, try penetrating oil and heat to loosen them before unscrewing. If screws still snap, you‘ll need to use a Dremel or pliers to grind down and remove the broken stub, then replace with fresh screws.
Why is my decorative drain cover cracked? Can I fix it?
Artistic covers crack easily under too much weight or pressure. They really can‘t be repaired, so the only option is to replace it. Pick a tougher option or use it somewhere without foot traffic.
How can I get my hair-clogged drain cover off?
Remove what you can with fingers, then use needle-nose pliers to gently pull out remaining hairs caught in the grate before fully removing the cover. Avoid just ripping it out quickly.
Is there a trick to getting bathtub drain covers off?
Bathtub drains get especially grimy. Be patient and use penetrating oil and heat to loosen the screws before trying to unscrew covers. The oil helps cut through soap scum buildup.
Help – I dropped the cover down the drain! What now?
First, turn off the water supply and drain all water left in the pipes. Then use needle-nose pliers or a small grabber claw tool to try fishing it back out. If that fails, you‘ll need to disassemble the piping underneath to retrieve it.
I hope this selection of FAQs helps prepare you to handle whatever comes up when removing drain covers!
