Step 7 · Install New Sillcock and Apply Flux
From the outside, carefully guide the new sillcock through the hole in the wall. Ensure the spigot nozzle is pointing downwards. Go back inside. Apply a thin, even layer of lead-free flux with a small brush to the cleaned exterior of the copper pipe and the cleaned interior of the sillcock fitting. Firmly push the sillcock fitting onto the end of the copper pipe until it is fully seated.
