Model 5300A Basic Auxiliary Drain

Auxiliary drains are installed in dry sprinkler systems in order to collect moisture and provide a method for its removal that will minimize the potential for excessive loss of air pressure and a tripping of the dry valve (NFPA 13: 8.16.2.5.3.5*, A8.16.2.5.3.5).

CollectanDrain Model 5300A

Improve your building's appearance and meet NFPA Code.

Auxiliary Drains become eyesores when they are not maintained properly. Signage falls off, valves break and water stains walls, replacement valves don't match, paint chips, and metal oxidizes. Poorly maintained auxiliary drains make your building look bad and they lower occupants trust in the building's infrastructure.

Give your occupants a sense of security and your building a consistent, appealing appearance by upgrading to a COLLECTanDRAIN® Model 5300A Basic Auxiliary Drain. The Model 5300A is a pre-assembled auxiliary drain designed to meet NFPA 13 and 25 guidelines addressing proper drainage while offering easy identification and a consistent appearance.

What Happens to Auxiliary Drains in Cold Climates

Auxiliary Drains and Cold Weather
  1. Moisture from the air within the dry pipe sprinkler system condensates and collects in the auxiliary drain.
  2. The condensate accumulates in the auxliary drain puddling into water
  3. When the temperature drops below freezing the water in the auxiliary drain freezes and expands up
  4. When the temperature rises above freezing some of the ice thaws and water collects at the bottom of the auxiliary drain while some of the ice remains frozen and floats on top.
  5. When the temperature drops below freezing again the floating ice freezes faster than the water below, and expands to attach to the nearby pipe walls. Then, as the trapped water below the ice plug begins to freeze it is forced downward causing a facture.
  6. When the temperature rises above freezing again, the ice plug begins to melt. If left unattended or if unnoticed when the ice melts system air is released and the dry valve is falsely tripped filling the entire system with water creating a potentially damaging flow from the broken auxiliary drain. In addition to occupant inconvenience a broken dry system can result in thousands of dollars in damage and repair costs and hours of maintenance and service time to restore the system to normal operation.
