The facility was a high-rise residential occupancy, designed to NFPA-13. Heads were QR semi-recessed chrome pend, K=5.6, ½" orifice, 155°. We replaced with same, but used 286° for a week or two until remediation was complete. No design change at all, only downside to entire project would have been a short time delay to fuse temperature should a fire occur in the interim. John O'Connor

Speaking of the residential heads before the 0.05 minimum of today? Sounds like a few nightmares having to re-calc and replace piping in some circumstances?

On day one we changed all heads to be subject to 175° heat-up to high temp heads, if I remember correctly, used 286°. They did the heat remediation, and after all the bugs are gone, we went back and replaced all heads with the original. Worked pretty well.

Bedbug exterminator has been hired. The process is to isolate and heat the rooms (2 per day) to about 175 degrees F with special heaters and therefore cook the bugs and their eggs. The property is sprinklered. Sprinkler contractor has been hired to drain the system, remove and plug heads in 2 rooms and refill. End of day, restore the system. Repeat process 17 times. Has anybody dealt with this? Is there a better way. Is there a cheaper way? C.
