SpaShopper offers the Tecmark Little General 3000 Series pressure switch model 3029, engineered with heavy-duty 25 amp capacity for demanding spa applications. This stainless steel switch features standard 1/8" MPT threading and utilizes two spade terminals for straightforward electrical connections. Its robust 25 amp rating makes this component suitable for various configurations, including vintage 115 volt plug-and-play hot tubs where heater power runs directly through the pressure switch.

This field-adjustable switch works seamlessly with multiple control systems including Balboa, Gecko, ACC, Hydroquip, Len Gordon, and Maddox brands. Serves as an excellent alternative to Balboa part numbers 30408 and 30409.

Common failure modes include: switch remaining open when pump pressure builds (preventing closure) or staying closed after pump shutdown (failing to open). Either condition typically triggers no-heat or overheat scenarios in most spa systems. Before replacement, verify pump operation and filter cleanliness, as these issues can also cause flow error codes.
