Universal Replacement Pressure Switch by Tecmark that can be used to replace switches in virtually any spa pack or control. Features a 1/8" MPT thread to go into your heater and 2 spade connectors to hook up your pressure switch cable.
This switch is a common failure point when you receive FLO or a blinking 3 dot code and have verified that your pump is running well in low speed, you have a good water level and have ruled out any clogged filters or closed gate / slice valves.
This switch comes pre-adjusted at 1.5 Psi (7.2 Kpa), but is field adjustable to 1-5 Psi and is the primary replacement for all Tecmark 3900 series switches. Common to find this switch used on many Hydro Quip, Gecko, Spa Builders and Balboa spa packs. Also used on 1999-2005 Gulf Coast Spas Cool Night Series (Except newer Dark Blue Gecko S-Class Boxes and Non GCS branded Hydroquip Boxes), Hydro Spas, Spa Builders and many more.
You will need teflon tape or thread sealant when installing this switch.
