Box 69 Waverly, MN 55390 Location: 4439 Hwy 12 SW Waverly, MN 55390 -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Jim Johnston Sent: Monday, December 21, 2009 12:02 PM To: [email protected] Subject: Residential Anti-Freeze Sytems Does anybody on the forum have experience with residential antifreeze? We have a community in Central Washington where sprinklers are required period no exception, the homes are high-end getaway homes. Some of the clients want antifreeze as a backup measure for freeze protection; we install Firefighter GL from the Noble Company in these systems all the components are piped in conformance with NFPA methods. We hydro the systems with water (AHJ makes us go 200 psi) then due a bucket test with water, we then drain the system and pull heads at the low points to get the remaining water out. We then pump the glycerin in and pull heads at the high points until the glycerin comes out, once filled we pump the solution up to about 10 psi above the static conditions of the water supply. Does this sound appropriate? Jim Johnston, P.E.
