Delta has been around for decades and is a well-established brand.
However, this also means property owners have aging shower faucets that are difficult to identify. For example, many are looking at a 25 year old delta shower faucet with no idea what model it is!
To identify a 25 year old delta shower faucet, it’s recommended to find the model number on the underside of the faucet. If no model number, find the instruction manual to locate it. If you have neither, type “Delta Faucet Catalog 1999” in Google to find your model.
The good part about having an old Delta shower faucet is how repairable it can be. The parts are readily available at local home hardware stores.
Just find the model number and you will be good to go.
Plus, if nothing else works, it’s never a bad idea to call customer service and speak to a trusted specialist. They have all of the model numbers on hand and will let you know which model is in front of you immediately.
Here is more on what to do when identifying a 25 year old Delta shower faucet.

Whether it’s a 20 year old Delta shower faucet or 30 year old Delta shower faucet, the same steps apply.
You will want to begin with the basics.
This includes locating the model number to identify the old faucet. In general, there are three places where the model number can be on an old Delta shower faucet.
- Underside of the Faucet

After this, just type in the model number online and find the parts you’re looking for.

2. Locate the Instruction Manual
Let’s assume the model number is not on the underside of the Delta shower faucet.
What are you going to do then? Do you just give up?
No, the next step is to locate the instruction manual at home. It is normal for people to not have the manual but it is something you should consider if the faucet was installed by you.
The manual might be lying around somewhere inside the property. The reason to go through the manual comes down to it having the model number written on it. You will also get a gist of what the Delta shower faucet is all about through the troubleshooting content.
3. Type “Delta Faucet Catalog 1999” To Find Your Model
If it is impossible to find the model number on the faucet or instruction manual, you will have to move on to the next step.
This step involves Google.
You are going to head online and type “Delta faucet catalog 1999.” The reason for doing this is to uncover all of the models that were released before 1999.
It is important to note, those models might be under the name “Brizo,” which was the name Delta was under at the time.

Are Old Delta Valves Universal?

If you are worried about an aging Delta valve, you don’t have to be.
Feel free to take it out and replace the valve with a brand-new one. It’s still going to work the way you want it to.
