Why the bundle

The Master Hub is where the whole system begins.

If you choose the course-only option, Tim shows you how to build the Master Hub yourself.

With the bundle, that part arrives already built. You start with the Hub and use the course to complete the downstream installation on your property.

Course only

Ridge impact sprinkler installation · PreFire Master Hub

“Tim installed the ridge impact sprinklers and a two-zone Master Hub on my house in Williams. Seeing the actual system come together on my own house made the entire concept much easier to understand. Once you see the Hub, the lines and the sprinklers working together, you can understand how the different parts of the system connect.”

Disclosure: Karin’s company, fivehats.ai, is paid by PreFire to build this website and produce the course. Tim installed her system at no charge for labor; she paid for the materials. Full disclosure

Zone finder

How many zones does your house need?

Five quick questions. You'll see which Master Hub Bundle fits your house, what it covers, and how to start smaller if you'd rather build in stages.

Do you want to cover every zone now, or build in stages? 1/5
What does your roofline look like? 2/5

Stand back from the house. Does the roof have one main ridge, or do other ridges stick out from it?

Do you have a deck attached to the house? 3/5
How long is your main roof ridge? 4/5

The long side of the house, end to end. A rough number is fine.

How high is your roof off the ground? 5/5

From the ground to the highest part of the roof. A rough number is fine. Impact sprinklers go about 30 ft apart, closer together on taller roofs.

Not sure? Send us photos and we'll size it for you.

If your roof has a lot going on, or you just want a second opinion, email or call us. A few photos are usually all it takes to tell you exactly which Master Hub you need.

Questions

Frequently asked questions

No. The pre-built Master Hub is currently available as part of the Course + Master Hub Bundle.

Yes. The standalone course teaches the complete installation, including how to build your own Master Hub.

Your Hub configuration depends on the zones in your system design. Detailed ordering guidance will be finalized before launch.

Yes. The Master Hub arrives with its main line and manifold both assembled. Any parts that have to be attached after delivery because of how the Hub is packed will be confirmed before launch.

The Master Hub, with its main line and manifold, is the start of the system, not a complete house kit. Laterals, fittings, sprinkler and nozzle components, controls and installation materials will depend on your property and system design.

Shipping is included in the bundle price. We currently ship to US addresses only.

Master Hubs are built to order. Final production and shipping lead times will be posted before launch.

The course can be refunded in full within 30 days of purchase, for any reason. A Course + Master Hub bundle can be cancelled for a full refund until your Hub goes into production. Because each Hub is built to your configuration, the bundle is final once it is in production, unless the Hub arrives damaged or defective. Full details are in the Refund Policy.

The course is designed to walk homeowners through the installation step by step. Always work within your abilities and use a licensed professional for any work outside your experience or where required by local regulations.

No. No wildfire-protection system can guarantee that a home will survive a wildfire. PreFire is one layer of a broader wildfire-readiness strategy and does not replace defensible space, home hardening, evacuation planning or official evacuation instructions.
