Measuring a drain stopper typically involves measuring the stopper itself or the drain opening it fits into.
To accurately measure a drain stopper, you can measure the length of the plunger on the drain stopper or, if the stopper is removed, measure the size of the hole in the tub that the stopper fits into.
Understanding the correct measurements is crucial, especially when you need to replace a old or broken drain stopper. Drain stoppers come in various types and sizes, so getting the right fit ensures proper drainage control and prevents leaks.
Methods for Measuring Your Drain Stopper
There are two primary methods you can use, as highlighted in the reference:
Method 1: Measuring the Stopper's Plunger
This method is useful if you still have the old stopper.
- Locate the Plunger: Identify the part of the stopper that goes down into the drain. This is often a shaft or post.
- Use a Measuring Tool: Use a measuring tape or ruler to carefully measure the length of the plunger from the point where it enters the drain up to a relevant stopping point (often the base of the stopper head or mechanism).
- Consider Width/Diameter: While the reference focuses on length, you might also need to measure the diameter of the part of the stopper that seals the drain or the width of any clips or mechanisms that secure it.
Method 2: Measuring the Drain Opening
If your stopper is missing, or you want to be sure the stopper fits the drain itself, measure the opening.
- Remove Obstructions: If possible, remove the drain cover or stopper by unscrewing it or detaching it according to its design.
- Measure the Diameter: Measure the size of the hole in the tub. Use a ruler or measuring tape to find the diameter (width) of the drain opening. Measure straight across the widest part of the circle.
- Consider Depth (Less Common): For some stopper types, you might also need a rough idea of the drain pipe depth, but diameter is usually the most critical measurement for fit.
Why Measure?
Knowing the dimensions of your drain stopper or drain opening is essential for:
- Replacement: Buying the correct size replacement stopper.
- Functionality: Ensuring the new stopper creates a proper seal to hold water in the tub or sink.
- Compatibility: Matching the stopper type (e.g., pop-up, lift-and-turn, push-and-pull) with the existing drain assembly.
Summary of Measurement Techniques
Here's a quick overview of the two main methods:
| Measurement Target | Tool Used | Key Dimension(s) to Measure | Notes |
|---|---|---|---|
| Existing Stopper | Measuring tape or ruler | Length of the plunger | Also consider diameter/width of sealing part |
| Drain Opening (Hole) | Measuring tape or ruler | Diameter of the hole | Requires removing old stopper/cover |
By following these simple steps using a standard measuring tool, you can accurately determine the size needed for your drain stopper.
