If you’re looking to replace your bathroom faucet, you’ll need to identify the brand or model number.
Here are some helpful methods to identify your bathroom faucet’s brand or manufacturer.
Checking Your Faucet’s Brand Logo
Step 1: Clean the faucet handles
Spray the faucet and handles with a good-quality glass cleaner to clean the dirt and grime covering the faucet’s brand name or logo.
Step 2: Wipe the dirt off with a cloth or rag
Look at the faucet and handles and find words or shapes that may help you identify a particular brand.
Step 3: Look for the faucet parts using a flashlight
Some faucet brand names and logos can be really tiny.
Other faucet brand names or logos are also located at unnoticeable parts of the product.
To get a better search of the faucet, use a flashlight to closely find the logo, name, or any identification.
It could be located at the curves of the faucet or the handles.
Step 4: Look for the model number, too
Not all faucet brands indicate model numbers on the product.
But should there be any, it can help you massively, especially if you’re looking for a replacement.
If you find a number on the surface of your faucet, try searching the model number online. It may direct you to the brand or manufacturer’s webpage.
Step 5: Look for the user manual
If you recently bought the faucet, look for the user manual, instruction booklet, or a small informational packet for more data.
Other Ways to Find Your Faucet’s Manufacturer
#1: Check beneath the sink
You may find a label attached to the supply line below your sink, which contains basic information like manufacturer name, model number, size, type, color, and other product specifications.
#2. Disassemble your faucet handle
Method 1: Look for the model number on the faucet
Step 1: Turn off the water supply
Step 2: Pull the cap off from the top of the handle
Step 3: Unscrew
Step 4: Lift the handle straight up once the screw loosens
Step 5: Look for the model number beneath the handle
Method 2: Counting the Splines
While your faucet handle is disassembled, look for the broach on the stem.
The broach is located at the top of the stem and fits into the bottom of the faucet handle.
Faucet manufacturers use different numbers of spines on the broach for identification or branding purposes.
Step 1: Count the number of splines (gear notches or pointed ridges) on the broach
Step 2: Mark a spline using a black or red marker to accurately count the splines
Step 3: Look up the number of splines online to see the manufacturer of your faucet
Method 3: Measuring the Stem
Using a measuring tool, identify the length of the stem.
This method will also help you identify the brand or manufacturer of your faucet.
Here are some common spline and broach combinations with their corresponding manufacturers:
