Quick choosing guide
- Freeze line & length: pick a freezeless wall hydrant with a stem length that extends past the heated wall.
- Backflow protection: choose anti-siphon/vacuum-breaker models where code requires.
- Connection type: match your plumbing—sweat/PEX/CPVC/FNPT—and confirm rough-in depth.
- Use case: select key-operated or box hydrants for public areas; hot/cold mixing for washdown stations.
Pro tips: Slope wall-hydrant bodies slightly outward so they drain, remove hoses before freezing temps, and keep box hydrants flush for a clean seal. Not sure which PRIER model or stem length you need? Tell us wall thickness, connection type, and location—we’ll recommend the right one.
