Step 6 · Prepare and Install New Tank Tee Assembly

This is the step most people slow down on. Take it one move at a time — there’s no rush, and you can rewind the clip as many times as you need.

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.
