01
Pumps & Motors
Look on the pump housing, strainer body, or motor label. Check both if possible, since motor and complete-pump model numbers serve different purposes.
Look first: pump body and motor nameplate.
Finding identification information
Where to Look First
Most pool equipment has identifying information somewhere on the unit. Knowing where manufacturers typically place labels can save time and help prevent ordering a part for the wrong model.
First stop
Look for the Manufacturer's Data Label
Search the accessible exterior of the equipment for a printed sticker, metal nameplate, or molded identification marking. Record the full model number exactly as shown, including letters, numbers, and suffixes.
Brand: identifies the manufacturer.
Model: identifies the equipment configuration or model family.
Serial: identifies the individual unit and may help with age or warranty questions.
Second stop
Check the Whole Unit, Not Just One Component
Some equipment has multiple labels. For example, a pool pump motor may have its own motor model number, while the complete pump has a different model number on the wet end or housing.
Complete equipment: use the whole-unit model when selecting assemblies.
Individual parts: a separate component number may be needed.
Replacement history: an installed motor or control may not be original.
Common Label Locations by Equipment Type
02
Pool Filters
Inspect the outside of the filter tank, upper housing, or manufacturer label. Note the exact model and filter size before selecting cartridges, grids, or tank parts.
Look first: tank-side label or model plate.
03
Heaters & Heat Pumps
Check the exterior cabinet or accessible rating plate. Record the model, serial number, fuel type where applicable, and electrical or input ratings.
Look first: exterior rating label; never remove hazardous covers just to locate it.
04
Salt Chlorinators
Inspect both the cell and its control or power unit. Cell and controller numbers may differ, and replacement compatibility can depend on both.
Look first: cell label and control-panel identification.
05
Automation Systems
Look for a system name on the controller, display, or load center. Older and newer generations may share a brand while using different parts.
Look first: controller exterior, display, and accessible system information screens.
06
Pool & Spa Lighting
Look for fixture or transformer information in safe, accessible locations. Voltage, fixture type, niche compatibility, and cord length matter for replacements.
Look first: documentation, transformer label, or accessible fixture records—not submerged electrical components.
07
Valves & Actuators
Brand and model markings may be molded into the valve body or printed on an actuator housing. Valve and actuator numbers may be separate.
Look first: valve body, lid, handle, and actuator label.
08
Other Treatment Equipment
UV units, ozone generators, chemical feeders, and mineral systems may carry identification on the housing, control module, or replaceable cartridge.
Look first: exterior housing and accessible product label.
If the label is faded or missing
Use More Than Appearance
Equipment shape and color can help narrow the possibilities, but they are rarely enough to confirm compatibility. Compare molded part numbers, dimensions, connection locations, control-panel markings, and available manuals or purchase records.
Photograph all sides of the unit that can be accessed safely.
Look for molded numbers on housings or components.
Check old invoices, installation documents, or equipment manuals.
A useful photo checklist
Capture These Four Views
A few clear photos can be more useful than a close-up of a single unknown component.
1. Full equipment pad and surrounding plumbing.
2. Complete equipment from the front or side.
3. All visible labels, markings, and model numbers.
4. Connections, controls, and any part being replaced.
The identification rule
Identify the Complete Unit Before Matching a Part
A model number on a motor, valve actuator, or control board may describe only that component. Whenever possible, confirm the complete equipment model first.
Safety comes firstDo not open energized electrical enclosures, disturb gas connections, or disassemble pressurized equipment to find a label. Use accessible markings and documentation, or have a qualified technician identify the unit.
Reading equipment identification labels
Understanding the Numbers
A pool equipment label can contain several different numbers. Knowing which one identifies the complete product—and which numbers describe individual parts or specifications—helps prevent costly replacement mistakes.

The three numbers to distinguish
Model, Part, and Serial Numbers
These numbers answer different questions. They may appear together on the same label or in separate locations.
Model number: identifies the product model or configuration.
Part number: identifies a specific component, kit, or assembly.
Serial number: identifies the individual manufactured unit.
Additional ratings: describe electrical, hydraulic, fuel, or capacity requirements.
What Each Number Actually Tells You
01
Model Number
Usually the starting point for identifying complete equipment. Manufacturers may use suffixes to distinguish revisions, configurations, or variants.
Use it for: identifying the correct product family and documentation.
02
Part Number / SKU
May refer to a motor, circuit board, seal, cartridge, complete assembly, or another individual component.
Use it for: matching replacement parts once the parent equipment is confirmed.
03
Serial Number
A unique identifier for the specific unit. It may help manufacturers determine production details, revisions, and warranty eligibility.
Use it for: service records and manufacturer support.
04
Electrical Ratings
Voltage, amperage, phase, frequency, and other electrical details describe the requirements of that particular component or unit.
Use it for: checking electrical compatibility—not identifying a whole pump from a motor label alone.
05
Capacity / Performance
Horsepower, BTU input, filter area, flow ratings, and similar specifications describe equipment capabilities, but do not uniquely identify a model.
Use it for: comparing operating requirements after identification.
06
Revision or Date Code
Some manufacturers use letter suffixes, revision identifiers, or production-date codes that can affect replacement compatibility.
Use it for: verifying the exact generation of equipment or parts.
Where people get confused
Two Labels Can Describe Two Different Things
A complete piece of pool equipment may contain separately labeled components. Always identify which part each number belongs to before choosing a replacement.
Pool Pump vs. Motor
The motor nameplate identifies the motor. The complete pump model may be marked on the pump housing, wet end, or original documentation. A replacement motor may also have a different model from the original.
Salt Cell vs. Controller
The cell and its power/control unit can carry separate model numbers. Compatibility depends on the system generation and the specific replacement being considered.
Filter Tank vs. Internal Media
A filter model may identify the tank assembly, while cartridges or D.E. grids have their own part numbers. Similar-looking filter housings can use different internals.
Automation Panel vs. Circuit Board
The outside controller identifies the system family, while an internal board may have a separate assembly or revision number. Board replacements require model-specific verification.
The most important rule
Never Match a Replacement Using One Number Alone
Start with the complete equipment model, then confirm the exact part, revision, and compatibility requirements. Physical appearance and similar ratings are not enough to guarantee a match.
Copy every characterLetters, suffixes, hyphens, and revision codes may be significant. Photograph the full label rather than relying on a partial number or memory.
Equipment identification · Photo checklist
Take a Few Photos
You do not need professional photography to identify pool equipment. A few clear, well-framed pictures can reveal the model, connections, and installation details that a written description may miss.
Why photos help
Show the Equipment and Its Context
A close-up can reveal a part number, but a wider view helps explain how the unit is installed. Both are useful when identifying equipment or checking a replacement.
What matters most
Clarity Beats Quantity
Four useful photos are better than ten blurry ones. Keep labels readable, show the full unit, and include connections without cropping away important details.
01 · Wide View
Photograph the Entire Equipment Pad
Stand far enough back to show the pump, filter, heater, controls, and surrounding plumbing in one frame.
Photo tip: Capture how the equipment connects—not just what one unit looks like.
02 · Identification
Get a Clear Photo of the Label
Move close enough to read every letter, number, and suffix on the accessible manufacturer nameplate or sticker.
Photo tip: Tap the label on your phone screen to focus; avoid glare and blur.
03 · Connections
Show Plumbing and Electrical Connections
Photograph accessible unions, pipe routing, valves, and exterior electrical connection points. These can affect replacement compatibility.
Photo tip: Include enough surrounding context to see which connection belongs to which unit.
04 · Full Equipment
Photograph the Unit From Multiple Angles
Capture the entire piece of equipment from the front and an accessible side, including controls, lids, and visible housing details.
Photo tip: A wide photo plus one close-up is usually more useful than several cropped images.
Useful extras
Additional Photos for Certain Equipment
Some replacements require details beyond the basic four views. Capture these only when relevant and safe to access.
Pumps & Motors
Photograph both the pump housing and motor label. These may identify different components.
Heaters & Heat Pumps
Capture the exterior rating plate and accessible gas or electrical specifications without opening hazardous compartments.
Lights & Automation
Show accessible controller labels, displays, transformers, and system information screens.
For readable images
Small Details Make a Big Difference
Good lighting and a steady camera can make faded or small identification labels easier to read.
Wipe dust from an accessible exterior label gently.
Use daylight or a flashlight without creating glare.
Take an extra close-up if the number is small.
Keep the original-resolution image when possible.
What not to do
Don't Disassemble Equipment for a Photo
Identification should not require opening electrical enclosures, disturbing gas connections, removing underwater light fixtures, or opening pressurized filters.
Use accessible exterior markings and documentation.
Avoid touching moving, hot, or energized components.
Ask a qualified technician if a label cannot be reached safely.
The simplest photo checklist
Wide View + Label + Connections + Full Unit
These four views provide a strong starting point for identifying pool equipment and narrowing down compatible replacement options.
One last detailWhen possible, include the full model number in writing as well. Letters, suffixes, and revision codes can matter just as much as the main number.
