If you've got a Febco backflow preventer from the 825Y or 825YA series (sizes 3/4\ to 1-1/4\), this 905111 rubber repair kit is exactly what you need for maintenance or repairs. This complete 18-piece kit contains all the rubber components to get your reduced pressure zone assembly working like new again. Over time, the rubber parts in backflow preventers can wear out, crack, or deteriorate, leading to leaks or reduced performance.

It's perfect for irrigation professionals, maintenance technicians, or handy homeowners who want to tackle their own repairs. Make sure this kit matches your specific Febco model before ordering. Having this on hand can save you from unexpected downtime and expensive service calls. Keep your backflow preventer in top working condition with this genuine replacement parts kit!
