AGF Model 5300 Pre-Assembled Auxiliary Drain/Drum Drip Valve for Dry Sprinkler Systems
This Auxiliary Drain Valve, also known as a Drum Drip or Low-Point Drain, arrives pre-assembled to save time and effort when installing dry-pipe fire sprinkler systems. These valves are installed where water trapped in dry piping can’t get to the main drain. Offers easy identification and a consistent appearance with the red label along the side, reading “Auxiliary Drain” allowing it to act as the sign as required by NFPA 13. With a galvanized steel body, brass valves, and a steel handle, this device is suitable for use in Dry or preaction fire sprinkler systems and/or sections of trapped piping that can hold more than 5 gallons of water. This product allows water and/or condensation to drip out of the pipes above, reducing corrosion and freeze-related damage with regular use.
Made in USA, compliant with Buy American requirements of the American Reconstruction and Reinvestment Act of 2009 (ARRA).
How to Use the AGF Model 5300 Auxiliary Drain/Drum Drip Valve
Don't open both valves at once and re-open the top valve after each use. A fully opened auxiliary drain will release pressurized air trapped in a dry or preaction system causing the system to activate (and fill pipes with water). Forgetting to open the top (inlet) valve after use will prevent water from draining out of the pipes above leaving the system vulnerable to corrosion and ice.
To remove trapped water with this auxiliary drain, simply:
- Close the upper valve.
- Place a drum or bucket beneath the auxiliary drain.
- Open the lower valve.
- Allow water to drip out.
- Close the lower valve and open the upper valve.
- Repeat these steps until little or no fluid is discharged.
For dry-pipe systems, NFPA 25 recommends operating this drain daily after a dry system operates, daily as temperatures approach freezing, and/or according to your facility's maintenance program.
