Campbell Pre-Assembled Tank Fitting Packages arrive fully built, pressure-tested, and ready to install — no bench assembly, no missing fittings, no leak-hunting. Each kit combines the tank tee or manifold, pressure switch, gauge, drain, relief valve, check valve, and isolation ball valve into one boxed, warranty-backed unit. Drop it on the tank and connect two lines.
