Decoding Old Delta Shower Valves: The Ultimate Identification!
This guide provides a comprehensive overview of identifying old Delta shower valve types. Understanding the different types is crucial for repairs, replacements, and general maintenance. Since Delta has been manufacturing shower valves for many decades, identifying the specific model can be challenging. This article aims to simplify the process.
Why Identifying Your Old Delta Shower Valve Matters
Before diving into the specifics of identification, let’s understand why knowing the type of your old Delta shower valve is so important:
- Repair Compatibility: Parts are not universally interchangeable. Knowing the specific valve type ensures you purchase the correct replacement parts, preventing further damage and saving time and money.
- Replacement Options: If repairing isn’t feasible, knowing the valve type will help you find a compatible replacement, whether you want a like-for-like swap or an updated system.
- Troubleshooting Accuracy: When diagnosing issues like leaks or temperature fluctuations, understanding the valve’s mechanics can significantly improve your troubleshooting accuracy.
- Historical Knowledge: For those interested in vintage fixtures, identifying the valve can provide insight into the age and features of your plumbing system.
Key Characteristics for Identifying Old Delta Shower Valve Types
Identifying old Delta shower valves relies on a combination of visual cues and operational characteristics. Here’s what to look for:
Handle Type and Design
The handle is often the easiest starting point. Delta has used several handle designs over the years.
-
Single Handle: Controls both temperature and flow with one lever.
- Ball Type: Known for their simplicity and use of a ball-shaped component within the valve body. (Often metal handle).
- Cartridge Type: Uses a cartridge to control water flow and temperature. (Often plastic handle).
-
Dual Handle: Separate handles for hot and cold water.
- Compression Valves: Feature washers that compress against a valve seat to stop water flow. (Visible packing nut).
- Ceramic Disc Valves: Use two ceramic discs that slide against each other to control water flow. (Smoother turning action).
Valve Body and Stem Configuration
The shape of the valve body and the configuration of the stem (the part that the handle attaches to) are important clues.
- Examine the Valve Body: Look for any markings, numbers, or logos. Even faded markings can provide valuable clues. Are the inlets and outlets aligned in a specific way?
- Observe the Stem: Is the stem threaded? Does it have a unique shape? Is it brass, plastic, or another material?
Cartridge/Ball Type and Features
The internal components, such as the cartridge or ball, are critical for identification.
-
Ball Valves: If you suspect a ball valve, try to identify the ball’s features:
- Material: Brass or plastic?
- Openings: How many openings are there, and where are they located?
-
Cartridge Valves: Cartridges are often color-coded or have specific markings:
- Color: What color is the cartridge body (e.g., blue, white, gray, red)?
- Markings: Look for any part numbers or manufacturer logos on the cartridge.
Location of Diverter (If Applicable)
If your shower has a diverter to switch between the tub spout and showerhead, note its location and operation:
- Tub Spout Diverter: A lever on the tub spout itself.
- Separate Diverter Handle: A dedicated handle above or below the main shower valve handle.
- Integrated Diverter: The diverter function is incorporated into the main shower valve handle (pull up or push down).

How can I tell which Delta shower valve I have if it’s very old and unmarked?
Start by visually inspecting the valve handle, escutcheon plate, and any exposed parts. Note the handle shape, number of handles, and the overall appearance. Compare these details with images and descriptions of different old delta shower valve types online. Knowing the era of your house can also provide clues.
What’s the most common issue that requires identifying an old Delta shower valve?
The most frequent reason is finding compatible replacement cartridges or stems. These parts wear out over time, causing drips, leaks, or difficulty controlling the water temperature. Accurately identifying your old delta shower valve types ensures you get the correct replacement.
Where can I find information about discontinued or very rare old Delta shower valve models?
While Delta’s website is a good start, online plumbing forums and communities dedicated to vintage plumbing fixtures can be invaluable resources. Sharing pictures and descriptions in these communities can often lead to identification by experienced users familiar with less common old delta shower valve types.
Are there specific features that commonly differentiate between different old Delta shower valve types?
Yes, the number of handles (single, double, or triple), the handle style (ball, lever, or knob), and the valve body material (brass or plastic) are key differentiators. Also, consider the stem type – some old delta shower valve types used specific stem designs unique to their era.
So, there you have it – a deeper dive into decoding those old delta shower valve types. Hopefully, this guide helps you navigate the world of Delta showers with a little more confidence! Happy plumbing!
