Buyer questions

What faucets does the Krowne 21-331L fit?

It fits all Krowne Royal Series faucets. It is the hot-side compression cartridge valve, so use it on the hot valve position.

Is this the hot or cold valve?

This is the hot-side cartridge (21-331L). The matching cold-side compression cartridge valve is the Krowne 21-330L.

What does the built-in check valve do?

The integral check valve helps prevent backflow and cross-contamination, keeping your hot water supply sanitary in a commercial setting.

Is it low lead compliant?

Yes. The 21-331L is low lead compliant and meets NSF/ANSI 372, along with NSF-61 and CSA ASME A112.18.1/B125.1 certifications.

Is it hard to install?

No. It ships fully assembled and drops straight into the Royal Series faucet base, so most repairs take only a few minutes with basic tools.

Can I pick it up or have it shipped?

We ship the Krowne 21-331L fast, nationwide, covered by our best price guarantee.
