|Res-Up Feeders attach to your brine tank and automatically dispense the Res-Up cleaner into the brine solution where it cleans the resin during the regeneration cycle.
The feeder hooks onto the tube inside your brine tank and you just pour some chemical in it and your water softener should last signifianly longer. A res-up feeder is essential if your raw water contains measurable amounts of iron.
The 12 cc feeder is for softeners up to 64000 grains (2 ft3 of resin) .
The 30 cc feeder is for larger softeners over 64000 grains.
