WHAT IS A 13D FIRE
SPRINKLER SYSTEM
• The 13D System may be used on one and two
family dwellings and manufactured homes up
to 10,000 sq. ft.
• Requires 2 sprinkler heads @ 13 GPM each =
26 GPM.
5
• 13D is a combined system with RFS Meter
There are ttwo methods
Th
th d off providing
idi a multilti
purpose sprinkler system.
1. Connect fire sprinkler system to toilet for
circulation.
2. Fully integrate fire sprinkler system with
cold water domestic lines.

HIGH ACCURACY
Cover a Broad range of domestic demands
HIGH HEAD LOSS (20PSI @ MAX CAPACITY)
HIGH MAINTENANCE (80+ PARTS)
Separate fire service required
