A spa circuit board is the "brains" behind your spa, controlling jet flow, filtration systems, water temperature, as well as the unit's high-limit sensors. Master Spa Parts offers a number of replacement circuit boards.
The 2 Inch Diverter Valve in Grey by Master Spas is a replacement for your home spa’s original diverter valve, the part of your spa that allows you to control jet water flow. This assembly kit comes with all of the pieces you need to install a new diverter valve in your spa.
