In the following sections, we’ll explore practical tips and straightforward methods to help you accurately identify your Delta shower faucet model. Whether you’re a DIY enthusiast or simply want to communicate effectively with a professional plumber, this guide will equip you with the knowledge you need to move forward confidently.

Examining the Faucet for Model Identification Clues

A practical first step when identifying a Delta shower faucet model is to closely inspect the faucet itself for any markings or labels. Many Delta faucets feature the model number or a series code stamped or printed on accessible parts. Common locations include:

  • The back or underside of the faucet handle
  • The escutcheon plate (the decorative plate behind the handle)
  • The valve body, accessible by removing the handle or trim
  • The cartridge inside the valve assembly

Removing the handle carefully often reveals a cartridge with a model number or manufacturer code. This code can be cross-referenced with Delta’s official documentation or online resources to pinpoint the exact model.

Be sure to use proper tools to avoid damage when disassembling parts. Keep an eye out for:

  • Stamped numbers or letters on metal parts
  • Printed stickers or labels on plastic components
  • Engraved or embossed logos that might indicate the series or style

If the faucet is older or heavily used, markings may be faded. In such cases, photographic documentation can help when consulting with Delta customer service or plumbing forums.

Using Delta’s Official Resources and Tools

Delta offers several resources that assist homeowners and professionals in identifying faucet models. Utilizing these tools can save time and ensure accuracy:

  • Delta Faucet Website: The official site provides product catalogs, manuals, and identification guides sorted by series and style.
  • Model Finder Tool: An interactive feature where you input visible markings or faucet characteristics to narrow down possible models.
  • Customer Support: Delta’s customer service can assist if you provide photos, cartridge numbers, or other identifying details.
  • Installation and Repair Manuals: These often contain detailed diagrams and part numbers that help correlate physical components to model numbers.

When using these resources, having the following information ready will improve the identification process:

  • Cartridge number (if accessible)
  • Finish type (chrome, brushed nickel, oil-rubbed bronze, etc.)
  • Handle style (lever, knob, cross handle)
  • Number of handles (single, dual, triple)
  • Any visible serial or model numbers

Identifying Models by Cartridge and Valve Type

Since the cartridge is a core functional component, identifying its type often leads directly to the faucet model or series. Delta uses a variety of cartridges across their product lines, and each has a specific shape, size, and number.

Common Delta cartridge types include:

  • RP19804: Classic single-handle cartridge used in many earlier models.
  • RP19804-UNBX: Universal cartridge compatible with various models.
  • RP19804-SS: Stainless steel variant for durability.
  • RP19804-HEX: Cartridge with a hex-shaped stem for specific series.

The cartridge number is usually printed on the cartridge itself or the packaging if you have replacement parts. Matching this number with Delta’s cartridge chart helps confirm the faucet’s model family.

Cartridge Number Description Common Faucet Series
RP19804 Standard single-handle cartridge Classic, Victorian, and many older models
RP19804-UNBX Universal cartridge for multiple series Monitor, Lahara, and related models
RP19804-SS Stainless steel cartridge for durability Brizo, Delta’s premium line
RP19804-HEX Hex-shaped stem cartridge Classic and some transitional models

Visual Style and Finish as Identification Aids

Delta produces numerous faucet models with distinct stylistic elements and finishes. Noting these characteristics can narrow down the possibilities significantly.

Key visual cues include:

  • Handle Shape: Lever handles, cross handles, knob handles, and paddle handles are often unique to particular series.
  • Spout Design: The shape and length of the spout, whether curved, straight, or angular, help differentiate models.
  • Finish Type: While many models come in chrome, others may feature brushed nickel, bronze, matte black, or polished brass finishes.
  • Trim and Escutcheon Shape: The size and contour of the escutcheon plate can indicate a specific style or line.

Taking clear photographs from multiple angles and noting these features can be extremely helpful when consulting identification guides or customer service.

Consulting Part Numbers and Replacement Components

Sometimes, the easiest way to identify a Delta shower faucet model is by examining replacement parts you have or can access. Parts such as cartridge kits, handle assemblies, or trim kits often come with part numbers that correspond to specific models or series.

Steps to leverage part numbers:

  • Locate any visible part numbers on screws, handles, or cartridge assemblies.
  • Use these numbers to search Delta’s parts database online.
  • Cross-reference the part number with available manuals or installation instructions, which typically include model information.
  • Contact Delta or authorized dealers with part numbers to confirm model identity.

This approach is especially useful when the faucet itself lacks clear model markings or when dealing with older, discontinued products.

Documenting and Recording Your Findings

Once you gather information from the faucet’s physical characteristics, cartridge numbers, and available documentation, it is helpful to compile these details systematically. A well-organized record will assist in future maintenance, repairs, or replacement.

Consider recording:

  • Model or series name (if identified)
  • Cartridge type and part number
  • Handle style and finish
  • Photographs of the faucet and key components
  • Date of installation or identification

Maintaining this information can save time and expense

Locating Model Information on Your Delta Shower Faucet

Identifying the exact model of a Delta shower faucet begins with locating key identifying information on the fixture or related documentation. Delta faucets typically include model numbers or series names that can be found in several common locations:

  • Under the Escutcheon Plate: Remove the decorative escutcheon (the visible plate around the faucet handle) by unscrewing or gently prying it off. The model number or style name is often stamped on the backside or inside surface.
  • Inside the Valve Body: If accessible, the valve body behind the handle assembly may have a model code engraved or printed. This typically requires removing the handle and possibly the cartridge.
  • On the Cartridge: The internal cartridge, which controls water flow and temperature, often carries a stamped or molded part number. Delta cartridges can be linked back to specific faucet models.
  • Original Packaging or Documentation: If you have the original installation manual, box, or sales receipt, these often list the model number or series name clearly.

Carefully inspecting these areas will provide the most direct route to identifying your specific Delta shower faucet model.

Using Delta’s Online Resources and Model Identification Tools

Delta Faucet offers several online tools and resources designed to assist consumers and professionals in identifying faucet models:

Resource Description How to Use
Delta Faucet Model Finder A web-based search tool to match faucet images and styles to model numbers. Enter faucet style keywords or browse categories; compare your faucet to images and specifications.

These tools streamline the identification process, especially when physical markings are difficult to locate or decipher.

Visual Identification by Design Features and Finish

When model numbers are unavailable, visual clues based on design characteristics and finish can help narrow down the Delta shower faucet model:

  • Handle Style: Note whether the faucet has lever handles, cross handles, knob handles, or a single-handle lever. Certain models are associated with distinctive handle shapes.
  • Spout Shape and Configuration: Observe the spout design—curved, angular, or with a waterfall effect. Some series have unique spout profiles.
  • Trim Plate Size and Shape: The escutcheon plate shape (round, square, or rectangular) and size can differentiate models within similar style families.
  • Finish Type: Chrome, brushed nickel, oil-rubbed bronze, and matte black are common finishes. Matching the finish to Delta’s catalog can assist identification.

Comparing these features to images and descriptions in Delta’s catalogs or online galleries will help pinpoint the exact model or at least the series.

Checking Cartridge Part Numbers to Trace Model Information

The cartridge inside a Delta shower faucet is often the key to identifying the model because each cartridge corresponds to specific faucet lines. To check cartridge information:

  1. Turn off the water supply to the faucet.
  2. Remove the handle and any visible trim to access the cartridge.
  3. Extract the cartridge carefully using pliers or a cartridge puller.
  4. Locate the part number stamped or molded on the cartridge body.

Once the cartridge number is found, consult Delta’s cartridge identification charts or online lookup tools to determine which faucet models use that cartridge. This method is highly reliable for identification, especially when other markings are missing or worn.

Consulting Professional Plumbers or Delta Authorized Dealers

If self-identification proves difficult, reaching out to professionals can expedite the process:

  • Licensed Plumbers: Experienced plumbers often recognize Delta faucet models by sight or have access to parts catalogs.
  • Authorized Delta Dealers and Service Centers: These outlets have comprehensive resources and can provide identification services, including ordering the correct parts.
  • Online Plumbing Forums and Communities: Sharing photos and details on specialized forums may yield identification assistance from knowledgeable users.

Engaging professionals ensures accurate model identification, which is critical for repairs, replacements, or upgrades.
