We have used both wax coated and poly coated. The problem with wax, is the wax coating is comprimised by the wrenches. That does not seem to be a problem with poly. We always leave a couple of new wrenches in the head box. For our wrecnhes, I take a new head and at least 2 wrenches to the local machine shop. He hard faces the wrench and then machines the wrench to fit the head.

If you look at the sprinkler cut sheets from Reliable (and others) they generally list the White Polyester heads as “corrosion resistant” and we’ve used those. I don’t think the white polys cost that much more than your standard sprinkler. We’ve used these in areas, like Camp Pendleton Hospital Parking Garage, which is exposed and pretty close to the ocean. Admittedly, I haven’t gone back years later to check on their condition. -Kyle M From: Sprinklerforum [mailto:[email protected]] On Behalf Of Charles Thurston Sent: Tuesday, October 2, 2018 12:49 PM To: [email protected] Subject: [EXTERNAL] RE: Fire sprinklers in harsh coastal environments We have used Nickle Teflon under buildings where the guys got to look at the ocean while installing them and they still look good 6 years later. Side Note I still have the old wax warmer and about 5 pounds of BeesWax we used to use for dipping them in.

Years ago, it wasn't uncommon for contractors to shop-dip sprinklers in wax before installing but no more. ALL finishes must be listed and factory-applied.
