Step 6 · Prepare and Install New Tank Tee Assembly
Prepare the threads of your new tank tee, pressure gauge, and any other threaded fittings. Wrap the male threads with 3-4 layers of Teflon tape in a clockwise direction (the same direction you will tighten the fitting). After wrapping with tape, apply a thin layer of pipe dope over the tape. Screw the new tank tee into the threaded connection at the bottom of the pressure tank and tighten it securely with a pipe wrench. Then, install the pressure switch, pressure gauge, and pressure relief valve onto the appropriate ports of the tank tee, tightening each one.
