Add the resup feeder to your water softener as a resin cleaning system.
Choose this option if you have iron above 1 ppm in your water supply.
This is a must for bacterial iron applications where no iron filter is installed ahead of the water softener.
This enhancement to a water softener will keep the resin and internals of the control valve clean, minimizing resin and injector fouling (the injector is the internal nozzle that creates a vacuum to draw the brine solution from the salt tank).
Mounts easily inside the salt tank, slowly wicking the liquid Resup into the brine tank.
Res-Up has been around longer than Res-Care® and Crystal Clean® products.
