What Will You Need?

Before you get started, make sure you have the following tools and materials on hand:

  • Cap or plug suitable for your drain size and type

10 Easy Steps on How to Cap a Basement Floor Drain

Step 1: Prepare the Area

First, it’s important to make sure the area around the floor drain is clear. Remove any debris or objects that may obstruct your work. If the drain has water in it, use a small bucket or towels to remove it.

Step 2: Choose the Right Cap

Ensure the Cap You Choose is Designed for Floor Drains

Now, you must choose the right drain cap or plug. The size and type of your drain will determine what kind of cap you need. This could be a twist-in, push-in, or screw-in cap. You can find these at your local hardware store or online. Ensure the cap you choose is designed for floor drains and fits your particular drain snugly to prevent leaks.

Step 3: Remove the Old Drain Cover

Using your screwdriver or drill, carefully unscrew any fasteners holding the old drain cover in place. Lift the cover off and set it aside. Be sure to handle this part of the procedure carefully, as the drain cover may be rusted and brittle. If it’s difficult to remove, you may need some lubricant or WD-40 to ease the process.

Step 4: Clean the Drain Opening

Before installing the cap, cleaning the drain opening thoroughly is important. This will ensure a tight seal and prevent any future leaks. Use an old toothbrush or a small wire brush to remove dirt or grime. After scrubbing, rinse the area with warm water and allow it to dry completely.

Step 5: Fit the Cap

It’s time to fit the cap once the drain is clean and dry. The installation process will differ depending on the type of cap you’ve chosen. For a twist-in cap, simply insert it into the opening and twist until it’s tight. For a push-in cap, align it with the opening and push until it’s secure. If you’re using a screw-in cap, you’ll need to screw it into place using your screwdriver or drill.

Step 6: Check for Leaks

Watch Closely for Any Signs of Leaking

Now that your cap is securely in place, it’s time to check for potential leaks. Pour some water around the drain cap and watch closely for any signs of leaking. If you notice any water seeping out from underneath the cap, it’s a sign that the cap is not fitted properly or is not the correct size. If this happens, you must adjust the cap or consider getting a different size.

Step 7: Secure the Cap

To further secure the cap and ensure a watertight seal, consider applying a waterproof sealant around the edges of the cap. This will help to prevent any future leaks and keep your basement dry. Allow the sealant to dry according to the manufacturer’s instructions before proceeding to the next step.

Step 8: Test the Drain

After completely dries the sealant, it’s time to test your new cap. Pour a generous amount of water over the cap and watch to see if any leaks occur. If the water drains away without any leakage, then your cap is properly sealed.

Step 9: Clean the Area

Now that your basement floor drain is successfully capped, it’s time to clean up. Wipe down the area surrounding the drain to remove any dirt or debris that may have fallen during the process. This is also the perfect time to dispose of the old drain cover properly, as it is no longer needed.

Step 10: Regular Maintenance

Now that the capping process is complete, regular inspection and maintenance of your capped drain is key to ensure a long-lasting, trouble-free seal. Check the drain periodically for any signs of leaks, and reapply the waterproof sealant as needed. Remember, maintaining your capped drain can prevent potential flooding and save you from costly water damage in the future.

By following these simple steps, you can easily cap a basement floor drain and ensure a watertight seal. It’s an important task that will help keep your basement dry and prevent potential problems.

How Do You Stop Water Coming Up Your Floor Drain?

If water is unexpectedly coming up through your floor drain, it could be a sign of a clogged or damaged pipe. You may need to unclog the drain using a plunger or call a professional for help.

Regular maintenance and cleaning are key to preventing water from coming up your floor drain in the future. This includes ensuring the drain cover is securely in place and regularly checking for any signs of clogging or damage.
