FAQ
Q: What pressure-sequencing issue arises when an Wholesale DN33 RIA Fire Hose Reel opens on the same floor as a running dry-riser outlet??
A: The RIA's 8 bar supply can back-feed down the dry-riser if the landing valve is cracked; check valves on both systems prevent this, but crews must still verify which system is pressurised before connecting additional lines.
Q: Why must Wholesale DN33 RIA Fire Hose Reels use manual gate valves instead of automatic shut-offs?
A: Manual control lets firefighters tactically conserve riser water and prevent waste if abandoned.
