An account has had the wet sprinkler system changed to antifreeze. Too bad the alarm guy did not know about the antifreeze. Maybe there is a reason for signs. When I checked the antifreeze solution at the far end, it was at 10°F. We will install an isolation valve so the system can be flow tested w/o loosing the antifreeze solution, and install a test port at the far end. The system is about 50 gallons, so we do not need to test the antifreeze except at both ends.
And isn’t the expansion tank supposed to be listed? The tank does not have any ID as to manufacturer or listing or capacity. Other tanks I have seen were mounted vertically, this one is horizontal. There are at least 2 places where the wet sprinkler piping goes vertically about 15 feet. Do we need to loosen the sprinkler heads to allow air to escape? We now get our antifreeze pre-mixed in 5 gallon buckets. Any leftover antifreeze will be left on site. And signs will be installed. One sign we make by cutting an empty bucket so the label becomes the sign. What did I miss? _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
