MixRite Check Valve 1"

Genuine OEM Replacement Check Valve for MixRite TF3 Series Injectors

The MixRite Check Valve 1" (Part #36000000258) is an OEM replacement check valve kit designed specifically for MixRite TF3 Series fertilizer injectors. It is compatible with MixRite models IMR2SO (571CW), IMR4SO (573CW), and IMR1 (566AG), which correspond to the TF3.002ON/OFF and TF3.004ON/OFF configurations with a 1" NPT body. The check valve is a critical internal component that prevents back-siphoning of fertilizer or chemicals into your water supply and ensures accurate, consistent dosing with each irrigation cycle. Replacing a worn or damaged check valve restores your injector's precision and extends the life of your entire fertigation system. For optimal system performance, pair your MixRite injector with a quality inline filter and backflow preventer.
