Photo identification. For the part with the numbers worn off, the discontinued one, or the one nobody at the counter recognizes. A specialist identifies it and quotes the match, usually within an hour.
- Pull it and snap it. A flat surface next to a ruler works best. Front, side and stem cover nearly every case.
- Tell us where to text the match. No account needed to send it.
- See the part number and your price before you pay anything, then order it shipped to the jobsite or shop.

What changes on every cartridge call
Less chasing parts. More closing jobs.
CartridgeID takes the messy part of a cartridge call, identifying it, finding it, pricing it, and getting it in your hands, and turns it into a simple workflow.
Skip the supply house run
Pull it. Snap it. Send it.
Send us a photo from the jobsite and get back to work. We handle the identification, including the oddball, discontinued, and worn-out cartridges that usually turn into a hunt.
No driving across town. No digging through bins. No texting photos around hoping somebody knows what it is.
Give your customer an answer
Know the part. Know the price.
Once we identify it, you see the part number and your price in one place. Quote the repair, get the customer's approval, and schedule the return trip while the job is still fresh.
No more, "Let me figure out what this is and get back to you."
Come back ready to finish
We ship it. You install it.
Order the part and have it shipped directly to your shop, truck, or jobsite. When you come back, you're coming back to finish the repair, not to keep searching for the part.
One less open ticket. One less parts run. One more job handled.
Turn the cartridge call into an easy call
You know the drill. Pull the cartridge. Drive to the supply house. Dig through bins or wait at the counter hoping someone recognizes it. If they don't, you're back to searching online, texting photos around, or leaving it sitting in your camera roll while you try to figure out what it is.
Meanwhile, your customer is asking the questions you don't have answers to yet:
What does it cost? When can you come back? How long until the part gets here?
CartridgeID takes all of that off your plate.
That is really all CartridgeID is: a cartridge identification tool you run from your phone, backed by a cartridge identification service staffed by people who have been reading these parts for years. Some pros know the common ones by rote. Others hit a discontinued or worn cartridge and need a second set of eyes. Either way, you send the photo and get a confirmed answer back, usually within an hour.
Pull the cartridge. Send us a photo. We identify it, source it, and get you a price. You quote the customer, schedule the return trip, and move on to your next call. If you want the detail, here is exactly how we read a cartridge, and our field guide to identifying a faucet cartridge covers the traits worth checking before you call it in.
Works the same whether you pulled it out of a sink or a wall: faucet cartridges and shower and tub valve cartridges both go through the same desk.
No supply house run. No guessing. No hunting down discontinued parts. No "I'll call you when I figure it out."
We've all got that one cartridge buried in our photos that we never figured out. Not anymore.

Plumber FAQ
Still got questions?
Do I need to remove the cartridge before submitting a photo?+
Removing the cartridge and photographing it on a flat surface next to a ruler gives us the most reliable identification. Three angles (front, side, and stem) cover nearly every ambiguous case.
How fast is the ID during a live service call?+
Photo submission takes about 60 seconds. Specialist identification comes back usually within an hour during business hours (Monday to Friday, 7am to 4pm Pacific).
How fast will the part arrive?+
You choose the shipping option at checkout and pay the actual carrier rate, with no handling fee. Standard ground typically arrives in 3 to 5 business days, and faster options are shown at checkout.
Do I need an account?+
Free signup gets you a plumber account with order history, saved shipping addresses, and reorder capability. Identification is free; you only pay if you order the part.
Is there volume pricing for multi-unit or commercial work?+
Yes. Bulk stocking orders for regular customers get volume-friendly pricing. Contact us with your typical monthly volume and we'll set you up. orders@cartridgeid.com
