Having difficulty finding compatible replacement wax coated sprinkler heads for an indoor pool area. Wax coated ones are the only ones that seem to last any significant time in this high humidity corrosive environment
Current heads are Tyco TY3211, K5.6, 165°, 1/2” npt
My preferred place to order from is Quick Response Fire Supply

But I don’t see any available and they say it’s a special order
Any ideas?
