Charles, Here in SE Florida we replace anything out side near the water after 3-5 years...they just rot away. The best I have seen are some of the Poly Coated Coro Resistant heads. I have seen them last 10 years or more. Wax over lead is for ever unless the wax gets scratched then it's over fairly quickly.
One good Tropical Storm or Hurricane with the Salt Spray gets everything outside with in 10 miles of the coast...otherwise we see normal wear 5 miles or more inland. Less that 3-5 miles they go fast unless they are coro resistant or wax coated. Now if you have a client with deep pockets you can get stainless steel and never replace them!! John W.

I am looking for suggestions on head finishes that will last for 10 years oceanfront and first row. wax over lead has been suggested as best for the area, Only problem is that are standard response, Not too good to replace existing quick response heads. Any luck with concealed heads? -- Best regards, Charles mailto:[email protected] _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
