Built from inside the plumbing supply industry.

Every plumber has stood at a supply-house counter with a mystery cartridge and lost the afternoon. The counter guesses. You drive back with what they gave you. It doesn't fit. You drive back to the supply house. Or you spend the evening calling supplier after supplier trying to source a cartridge for a discontinued line.

CartridgeID is that specific problem solved: snap a photo, our specialists identify the exact model — including discontinued and worn-stamp cases — and we quote the aftermarket replacement from our trusted suppliers, shipped direct to your jobsite. We work across faucet cartridges and shower and tub valve cartridges alike.

We don't rely on AI-only vision matching. Two visually similar cartridges can have completely different internal geometries — that's exactly the failure mode that gets the wrong part shipped. Our team's only job is cartridge identification, and we do it human-verified before we ever quote a part. You can read the checks a specialist runs on every cartridge, or see how this fits a plumber's day.

CartridgeID is headquartered in San Jose, California. Our specialist team works identification remotely — you submit from anywhere in the United States and we ship the replacement direct to your jobsite through our trusted suppliers.
