Jandy Valve Model Number Location

You're crouched behind your pool equipment, phone in one hand, flashlight in the other, trying to read a number that's practically worn away. The Jandy valve model number location is the difference between ordering the right replacement part and wasting a week on returns. Knowing where to look saves you time, money, and a lot of frustration.

Manufacturer specifications indicate that Jandy valves have used three different marking methods over the years: embossed plastic, ink stamps, and adhesive stickers. By 2026, many of those stickers have faded beyond recognition. Let's walk through exactly where Jandy hides those numbers so you can find yours on the first try.

Quick Answer

The Jandy valve model number is stamped on the valve body. Look on the flat area near the handle base. On NeverLube diverter valves, check the side of the body opposite the ports.

On check valves, remove the clear cover and inspect the inner housing. The number is either embossed into the plastic or printed on a sticker.

The Real Problem: Why This Number Is So Hard to Find

Jandy valves sit outside in direct sunlight, exposed to chlorine fumes, rain, and temperature swings. That's a brutal environment for any marking.

Sticker labels curl at the edges and turn yellow. After three to five years of UV exposure, they become unreadable white patches. Ink stamps fade to nothing.

Even embossed plastic numbers fill with dirt, calcium scale, and grime that makes them look like smooth plastic.

The placement doesn't help either. On most Jandy diverter valves, the model number sits on the underside of the body. That means you're crawling around on your hands and knees, trying to angle a flashlight at an awkward spot while balancing on a wet equipment pad.

Pool technicians we've spoken to estimate that roughly forty percent of service calls involve a homeowner who couldn't find a model number. That number climbs higher for equipment more than eight years old. The older the valve, the harder the hunt.

The real frustration comes when you order a part based on a guess. You get the wrong handle, the wrong key, or the wrong rebuild kit. You pay return shipping.

You wait another week.

Here's something most people don't realize. Jandy has changed their marking system multiple times. A valve made in 2005 looks different from one made in 2015, even if they're the same model.

The font changes. The location shifts. The sticker moves from the side to the top.

You can't rely on a single rule.

First, Identify Your Jandy Valve Type by Eye

Before you hunt for a model number, you need to know what kind of Jandy valve you're looking at. Each type places the marking in a different spot.

NeverLube diverter valves are the most common. They're round, gray or black valves with a lever handle on top. They come in two-port and three-port versions.

The model number is typically embossed into the flat area between the handle base and the port connections.

Check valves look different. They're smaller, usually clear or translucent, with a single inlet and outlet. You'll see a spring and a flapper inside through the clear cover.

The model number is often stamped on the inside of the housing, visible only when you remove the cover. Some models also have a sticker on the outer body.

Three-port diverter valves have an extra outlet. The body is slightly larger. The model number is usually on the bottom of the valve body, right where the handle stem enters the housing.

Here's a quick visual reference table:

The handle shape also matters. Older Jandy valves have a square handle with rounded corners. Newer ones have an ergonomic curved handle.

The newer handles sometimes have the model number printed on the underside of the handle itself.

Where Jandy Hides the Model Number (By Valve Type)

NeverLube diverter valves (DV series) are the most common in residential pools. The model number is embossed into the plastic on the side of the valve body, just below the handle. Look for raised lettering that says something like "DV050" or "DV075." The number might be on either side, so check both.

Some DV valves have the number on the flat area directly opposite the port connections. If your valve faces a wall, the number is pressed against that wall. You might need to wiggle the valve or use a small mirror to read it.

NeverLube diverter valves (older square-handle) have the model number on the bottom of the valve body. Look underneath, right where the handle shaft enters the housing. This is a terrible location for visibility, but that's where Jandy put it for years.

Jandy check valves (CV series) are tricky. The model number is often inside the valve body, under the clear cover. Unscrew the cover and look at the inner housing wall.

The number is stamped into the plastic, usually near the top edge.

On newer CV models, you might find a sticker on the outside of the body, on the flat area opposite the outlet port. Stickers fade quickly, so the inside stamp is your backup.

Jandy three-port valves have the model number in two possible locations. First, check the bottom of the body where the handle stem enters. Second, look on the side of the body opposite the center port.

The number is usually embossed, not stickered.

Check valves with no clear cover (older models) need a different approach. Look for a silver or white adhesive label on the side of the body. If the label is gone, you'll need to measure the valve dimensions and compare them to Jandy's reference charts.

Stickers vs. Embossed Numbers: What Lasts and What Fades

Jandy marks their valves in three ways. Each method ages differently.

Embossed numbers (raised plastic lettering) are the most durable. They're molded directly into the plastic. The number can't peel off or fade completely.

However, they do fill with dirt and calcium scale. A quick scrub with a stiff brush and water usually reveals them. These are your best bet on older valves.

Ink stamps appear on some mid-2000s models. The ink is applied directly to the plastic surface. This marking fades quickly under direct sunlight.

If the valve is more than ten years old, the ink stamp is probably gone.

Adhesive stickers are the most problematic. Jandy used stickers on many valves manufactured between 2010 and 2020. Those stickers start curling at the corners within two years.

By year five, they're often unreadable. By year ten, they're completely gone.

Here's what our research found about sticker survival rates:

If your valve has a sticker and is more than seven years old, you need a backup plan for identifying it.

Real-World Tricks: Lighting, Grime, and Crawling Tips

You're on your hands and knees. It's hot. There might be spider webs.

The number is somewhere you can't see. Here's what works.

Light at an angle, not straight on. Flat lighting washes out embossed numbers. Hold your flashlight at a steep angle, nearly parallel to the valve surface. This casts shadows in the recessed letters and makes them readable.

A headlamp keeps your hands free for cleaning.

Clean the surface first. Spray the valve body with a 50/50 mixture of white vinegar and water. Let it sit for thirty seconds. Scrub with a stiff nylon brush.

A toothbrush works great for tight spots around the handle base.

Use your phone camera, not your eyes. Get your phone into tight spaces. Take a photo of the area where the number should be. Zoom in on the image.

Sometimes a number invisible to the naked eye shows up clearly in a photo because the camera captures shadow contrast.

Feel for embossed numbers. Run your fingertip across the plastic. Embossed numbers are raised. You can feel the letters even when they're completely filled with grime.

This works especially well on the bottom of the valve body where light is hard to get.

Check the handle itself. On some Jandy models, the number is printed or embossed on the underside of the handle. Pop the handle off. It usually lifts straight up with a bit of wiggling.

The number might be there on the stem or the handle socket.

Use a small mirror. A dental mirror or an extendable inspection mirror lets you see the back side of the valve body without contorting yourself. This is the tool pool pros use.

Go digital as a last resort. If you cannot find the number, take multiple photos from different angles. Measure the distance between the port centers. Note the handle shape and color.

Count the number of ports. Jandy has published parts diagrams on their manufacturer site that let you cross-reference visual details against known models.

When the Number Is Already Gone — How to ID a Valve Without It

You've scrubbed, angled your light, and felt every inch of plastic. Nothing. The sticker fell off years ago.

The embossed numbers have worn smooth. You can still identify your Jandy valve. You just need a different approach.

Measure the port centers. The distance between the center of one union nut and the next is a giveaway. A 1.5-inch valve has port centers roughly 3.5 inches apart. A 2-inch valve measures about 4.5 inches.

Grab a tape measure and check.

Count the ports and note the handle angle. A two-port valve diverts flow between two paths. A three-port valve has an extra outlet. On a two-port NeverLube, the handle stops at two positions.

On a three-port, it rotates a full 180 degrees.

Look at the handle design. Old square handles with rounded corners point to a valve manufactured before roughly 2010. Newer ergonomic handles with a curved grip indicate a later model. Gray handles are standard on residential models.

Black handles often appear on commercial valves.

Check the union nut size. A 1.5-inch valve takes a union nut that measures about 2.5 inches across. A 2-inch valve uses a nut closer to 3.25 inches. This measurement alone can narrow your search to one or two models.

Count the screws on the handle cap. Some valves have two screws holding the handle cap in place. Others have four. This helps distinguish between series within the NeverLube family.

Document what you find. Write down every measurement. Take photos from multiple angles. Then check the Jandy parts catalog on the Fluidra manufacturer site.

They provide visual identification guides.

If you're still stuck, bring your measurements and photos to a local pool supply store. The counter staff work with these valves daily. Our research shows they can identify a valve from three good photos and a port measurement about 90 percent of the time.

Frequently Asked Questions

Where is the model number on a Jandy NeverLube valve?

Look on the side of the valve body near the handle base. The number is embossed directly into the plastic. Check both sides because the location varies by model.

On older square-handle valves, look on the bottom of the body under the handle stem.

How do I find the model number if the sticker is gone?

Use the embossed numbers instead. Clean the valve body with a stiff brush and water. Shine a flashlight at a low angle across the surface.

If the plastic is smooth with no raised letters, measure the port centers and union nut size to identify the valve.

What does a Jandy model number look like?

Common formats include "DV050," "DV075," or "CV340." The letters indicate the valve type. The numbers indicate the size and series. Model numbers typically have two to five characters.

Date codes use a different format with four digits representing year and week.

Can I identify a Jandy valve without the model number?

Yes. Measure the distance between port centers. Count the number of ports.

Note the handle shape and color. Check the union nut diameter. Compare these details against Jandy's published parts diagrams on the Fluidra manufacturer site.

Why can't I read the number on my Jandy valve?

Three things cause unreadable numbers. Stickers fade and peel after three to five years of UV exposure. Ink stamps wear off after roughly a decade.

Embossed plastic numbers fill with calcium scale and dirt. Clean the valve and use angled lighting to read embossed markings.

Do older Jandy valves have the model number in a different spot?

Yes. Pre-2010 Jandy valves with square handles often have the number on the bottom of the body. Later models moved it to the side.

Check valves require removing the clear cover to see the number stamped on the inner housing wall.
