4037P Pressure Switch
Note : No Longer comes with the brass connector, photo is for show purposes only
The Tecmark Pressure Switch screws into the heater tube inside many hot tubs and spas, it has an adjustment on the top but this should not be moved and is factory set.
Used in many brands of hot tub including: Dolphin Spas, Arctic Spas
- you can connect 2 spade connections or 2 wires to this switch
This component is easily tested for faults, presuming every other aspect of the hot tub works fine and the filters are clean and you have good water flow, simply loop out your existing pressure switch with a small piece of wire and if the problem is resolved replace for a new switch.
*Note: We do not recommend to adjust the pressure switch setting on the top of a Tecmark pressure switch, this has been set by the manufacturer to a specific pressure, if the problem still persists after replacement you will most probably have a different fault on the hot tub or spa.
