Seamless pool flow control for reliable filtration and easy maintenance. Key benefits Precise water routing: Divert and control flow paths to optimize filtration, backwash, or cleaning without reconfiguring plumbing. Reduced downtime: Quickly switch flow directions for maintenance or seasonal changes, minimizing service time for public or private pools. Leak-resistant connections: Supplied hose clamps ensure a secure, water-tight fit for the most common filter hose sizes. Professional and DIY friendly: Designed for pool-service technicians and pool owners who want a practical way to improve filtration performance. What it does Acts as a changeover/ diverter valve and hose adapter to manage water flow between pumps, filters, and auxiliary equipment. Simplifies isolating components during service, adjusting flow for cleaning or backwash, and routing water to alternate lines. Key attributes Material: Durable ABS construction — lightweight, impact-resistant, and suitable for pool environments. Included parts: Valve adapters plus hose clamps for secure installation. Compatibility: Fits both 1 1/4 inch and 1 1/2 inch filter hose connections without modification. Performance: Provides a tight seal and reliable control of flow paths when installed with the included clamps. Typical applications 1. Public pools: Rapidly change filtration routes during heavy use periods or when switching between main and backup filters. 2. Residential pools and spas: Redirect water between pool and spa lines, or engage cleaner and return lines without swapping fittings. 3. Maintenance and repair: Isolate the filter or pump for cleaning or component replacement while maintaining circulation through alternate lines. Installation and use Simple hose-clamped installation to existing filter connections sized 1 1/4" or 1 1/2". Suitable for routine service tasks and as a permanent plumbing aid to improve filtration efficiency. Reliable, straightforward control of pool water flow where compatibility, leak resistance, and ease of use matter.
