This Refill for 2-Media and 2-Tank Whole House Filter has all the filtering material you need to replenish your 2 tank whole house filtration system – the DT-40R Chlorine Plus Filter System. Your system has a backwash head on one of the tanks.
There are two options. The handyman choice, which is Raw Media. Take the old media out and put in the new. Or the DIY choice, which is get entire new filled tanks. You keep your backwash head, but swap out the tanks.
Your tanks may be like the blue ones in the photos, or the white ones. In either case, this is the right media for the DT-40B.
