Kill power, Thread the old one out, and thread the new one in, replace the wire connections, dry up any water before you turn the breaker back on, DONE!!! I left the water in my tub, I just covered the rest of the control board with some plastic drop cloth and taped it. Soaked up excess water with a towel and allowed to air dry for a bit before restoring power. Cleared my FL2 code and has been working great.

Great pressure switch. Have had hot tub for 20 years so decided better do some preventative maintenance and replace heater element. In the process I broke the original pressure switch off the manifold. Got this one in about 2-3 days and got tub back together and running great again.

I replaced my Balboa 30408 Pressure Switch with the Tecmark 3903-BP and it worked right out of the box.
