How to Replace a Tub Waste and Overflow: A Simple DIY Guide

Replacing your tub waste and overflow isn't as daunting as it sounds! If you're dealing with a leaky stopper, a corroded drain, or simply want to upgrade your bathroom fixtures, this DIY guide will walk you through the process step-by-step. We'll cover everything from gathering the right tools to ensuring a watertight seal, so you can confidently tackle this plumbing project and enjoy a relaxing, leak-free bath.

Before we dive into the "how," let's quickly cover the "why." A properly functioning tub waste and overflow system is crucial for several reasons:

  • Prevents Leaks: The most obvious reason! A damaged or worn-out overflow or drain can lead to water leaking behind walls, causing mold, mildew, and costly structural damage.
  • Maintains Water Level: A working overflow ensures that your tub doesn't overflow (duh!), preventing water from spilling onto your bathroom floor.
  • Proper Drainage: A clear and efficient drain allows water to empty quickly, preventing buildup and potential clogs.

Replacing your tub waste and overflow is a relatively inexpensive and straightforward project that can save you a lot of headaches (and water damage) in the long run.

Ready to get started? Follow these steps carefully for a successful installation.

Step 1: Gather Your Tools and Materials

Before you even think about turning off the water, make sure you have everything you need. This will prevent frustrating mid-project trips to the hardware store. Here's a list of essential tools and materials:

  • New Tub Waste and Overflow Kit: Choose a kit that matches your tub's existing configuration (more on this in the buying guide section).
  • Plumber's Putty: This is essential for creating a watertight seal around the drain flange.
  • Pliers (Channel-Lock Type): For loosening and tightening connections.
  • Adjustable Wrench: Another tool for tightening and loosening connections.
  • Screwdrivers (Flathead and Phillips): For removing screws and tightening new ones.
  • Hacksaw or PVC Cutter: You may need to cut the overflow or drain pipes to length.
  • Rag or Sponge: For cleaning up any spills.
  • Bucket: To catch any water that may be trapped in the drain pipes.
  • Penetrating Oil (Optional): For loosening stubborn connections.
  • Gloves: To protect your hands.
  • Safety Glasses: To protect your eyes.

Step 2: Turn Off the Water Supply

This is a crucial step! Locate the shut-off valves for the hot and cold water lines that feed your bathtub faucet. Turn them both off completely. If you can't find individual shut-off valves, you may need to turn off the main water supply to your house.

Step 3: Remove the Old Overflow Plate and Stopper

Start by removing the overflow plate, which is the plate located below the faucet. Use a screwdriver to remove the screws holding it in place. Then, carefully remove the plate and its linkage (the rod that connects the plate to the drain stopper).

Next, remove the drain stopper. Depending on the type of stopper you have (lift-and-turn, pop-up, etc.), the removal method will vary. Some stoppers simply lift out, while others require you to unscrew a small screw from the center.

Step 4: Loosen the Drain Flange

Now comes the tricky part: loosening the drain flange (the metal ring around the drain opening). The flange is usually held in place by a large nut underneath the tub.

This is where the penetrating oil can come in handy. Spray some penetrating oil around the nut and let it soak for a few minutes to help loosen it.

Using a pair of pliers or an adjustable wrench, carefully try to loosen the nut. If it's really stuck, you may need to use a basin wrench, which is a specialized tool designed for reaching nuts in tight spaces.

Once you've loosened the nut, you should be able to unscrew it by hand. Have a bucket ready to catch any water that may be trapped in the drain pipes.

Step 5: Remove the Old Drain Assembly

With the nut removed, you should be able to pull the old drain assembly out from the top of the tub. It may be a bit stubborn, so try twisting and wiggling it gently.

Once the old assembly is out, clean the drain opening thoroughly with a rag or sponge. Remove any old plumber's putty or debris.

Step 6: Prepare the New Drain Assembly

Now it's time to install the new tub waste and overflow. Start by applying a generous amount of plumber's putty to the underside of the new drain flange. Roll the putty into a rope shape and press it firmly against the flange.

Step 7: Install the New Drain Assembly

Insert the new drain flange into the drain opening from the top of the tub. Make sure it's centered and flush with the tub surface.

From underneath the tub, slide the rubber washer and then the metal washer onto the drainpipe. Then, screw the nut onto the drainpipe and tighten it by hand.

Use a pair of pliers or an adjustable wrench to tighten the nut further. Be careful not to overtighten it, as this could crack the tub. You want a snug, watertight seal, but not so tight that you risk damaging anything.

Step 8: Install the Overflow Pipe and Plate

Next, install the new overflow pipe. Insert the pipe into the overflow opening from behind the tub.

Attach the overflow plate to the pipe from the front of the tub, using the screws provided in the kit. Tighten the screws until the plate is snug against the tub surface.

Step 9: Connect the Drain and Overflow Pipes

Connect the drain and overflow pipes to the tee fitting (the Y-shaped fitting that connects the drain and overflow pipes to the main drainpipe). You may need to cut the drain and overflow pipes to length using a hacksaw or PVC cutter.

Make sure all connections are tight and secure. Use PVC cement if necessary (depending on the type of pipes you're using).

Step 10: Test for Leaks

This is a crucial step! Turn the water supply back on and fill the tub with a few inches of water. Check for leaks around the drain flange, overflow plate, and pipe connections.

If you see any leaks, tighten the connections further or reapply plumber's putty as needed.

Once you're satisfied that there are no leaks, fill the tub to the overflow level and check again.

Step 11: Finishing Touches

If everything looks good, congratulations! You've successfully replaced your tub waste and overflow.

Clean up any mess and dispose of the old parts properly.

Having the right tools can make this whole process much smoother. Here are a couple of recommendations specifically for dealing with those stubborn drain nuts:

  • RIDGID 31375 Model 5 Basin Wrench: This wrench is a lifesaver when it comes to reaching those hard-to-access nuts behind the tub. Its spring-loaded jaws provide a secure grip, and its telescoping handle gives you extra leverage. This will save you time and frustration.
  • WD-40 Specialist Penetrant: As mentioned earlier, penetrating oil is your best friend when dealing with corroded or stuck nuts. WD-40 Specialist Penetrant is specifically designed to break down rust and corrosion, allowing you to loosen even the most stubborn connections without damaging the pipes. The fast acting formula with Blu Torch Technology penetrates rust, scale, and corrosion to free stuck or seized parts. Plus, it has a Smart Straw, so it can be used as a spray or stream.

Using a quality basin wrench and penetrating oil can significantly reduce the time and effort required to remove the old drain assembly, making the entire replacement process much easier.

  • Choose the Right Kit: Tub waste and overflow kits come in different configurations to match different types of tubs (standard, soaking, etc.). Make sure you choose a kit that's compatible with your tub.
  • Measure Twice, Cut Once: When cutting the drain and overflow pipes to length, be sure to measure accurately to avoid making mistakes. It's always better to cut a little too long than too short. Make sure you have the right kind of tools for these kinds of cuts.
  • Don't Over-Tighten: Overtightening the connections can damage the pipes or the tub. Snug is good; crushed is not.
  • Use Plumber's Putty Generously: Plumber's putty is your friend! Don't be afraid to use plenty of it to create a watertight seal.

FAQ:

  • Q: How do I know what kind of tub waste and overflow kit I need?
    • A: Take a picture of your existing waste and overflow system and bring it to your local hardware store. The staff there can help you identify the type of kit you need. Also, it helps to measure the diameter of the drain pipe.
  • Q: Can I use Teflon tape instead of plumber's putty?
    • A: Teflon tape is generally used for threaded connections, while plumber's putty is used for creating a seal between surfaces. For the drain flange, plumber's putty is the preferred choice.
  • Q: What if I can't loosen the nut on the old drain assembly?
    • A: Try using more penetrating oil and a basin wrench. If that doesn't work, you may need to call a plumber.
  • Q: My new stopper doesn't seal properly. What should I do?
    • A: Make sure the stopper is properly adjusted. Some stoppers have an adjustment screw that allows you to fine-tune the seal. If that doesn't work, you may need to replace the stopper with a different one.
