Does anyone know what this pipe is coming out of the exterior wall of my house just below my hose spigot? I have one by each of the hose spigots around my house. The pipe appears to have some sort of wire coiled up around it and has a soldered on cap. Is this an interior house water pipe? I hope! I want to use it for a misting system if it is since the house water is filtered and softened. Sorry for the bad picture it was the only one I had. House was built in 06'. Thanks.
