The drains need periodic emptying or collected water can freeze and break the drain, activate the system and cause water to spill into a facility. A broken drain can be an inconvenience or a catastrophe, so proper freeze protection is vital to keep systems operating correctly and buildings in good condition.  **Stop the Flood with Flood Eliminator**  [AGF manufacturing’s](https://www.supplynet.com/brand/agf-manufacturing/) [COLLECTanDRAIN Model 5900FE Flood Eliminator](https://www.supplynet.com/model-5900-flood-eliminator/) is an economic and simple option for facilities to avoid catastrophic flood damage while solely relying on maintenance for freeze protection. Should a drain freeze and break, the Flood Eliminator will sense the sudden pressurized flow of water and restrict to eliminate the flooding that would have occurred. It does not interfere with normal auxiliary drain function and resets itself when the system is reset.  **Water Detector Alarms Simplify Maintenance**  Many auxiliary drains freeze and break because maintenance personnel either forget about them completely, miss one by accident, or don’t realize they need to be drained of even the smallest amount of accumulated condensation. What if the drum drip could tell staff when it needs draining? AGF’s [Model 5100ALBV](https://www.supplynet.com/ball-vlv-w-water-det/) detects water in the collection assembly and triggers a visual and audio alert. That way, staff know exactly which drain they need to tend to. They can also wire it to a Fire Control Panel or BMS for remote notification.   **Heated Cabinets for the Ultimate Protection**  AGF also offers a COLLECTanDRAIN line of heated cabinets that are designed to protect even the most problematic auxiliary drains by encasing them in a temperature-controlled environment. The energy-efficient heater includes a thermostat, so it will only turn on when needed. The drain can safely accumulate condensation without freezing and notifies maintenance staff (locally and/or remotely) when it needs attention. [Model 5400](https://www.supplynet.com/products/accessories/collectandrain-heated-aux-drain-cabinet-5400/) is the original, while [Model 5450](https://agfmfg.com/heated-auxiliary-drain-cabinets/5450-self-maintaining/) and [5500](https://www.supplynet.com/collectandrain-heated-aux-drain-cabinets-5500/) provide self-maintaining and automatic draining functions.  [Product Innovations](https://blog.vikinggroupinc.com/tag/product-innovations), [Business Partners](https://blog.vikinggroupinc.com/tag/business-partners) ## Related posts [![Viking SupplyNet Products](https://blog.vikinggroupinc.com/hs-fs/hubfs/Blog-Post-Image_AGF-RPs-Mar-02-2023-02-04-27-5369-PM.png?height=200&name=Blog-Post-Image_AGF-RPs-Mar-02-2023-02-04-27-5369-PM.png)](https://blog.vikinggroupinc.com/the-ultimate-solution-for-faster-floor-control-installations-agfs-ultimate-riserpack-kits) [SupplyNet.com](https://blog.vikinggroupinc.com/tag/supplynet-com), [Business Partners](https://blog.vikinggroupinc.com/tag/business-partners) ## [The Ultimate Solution for Faster Floor Control Installations](https://blog.vikinggroupinc.com/the-ultimate-solution-for-faster-floor-control-installations-agfs-ultimate-riserpack-kits) [Ellen Davis](https://blog.vikinggroupinc.com/author/ellen-davis) Mar 2, 2023, 9:04:33 AM Visit SupplyNet.com today to purchase your Ultimate RiserPACK Kits!
