Filter / Softener Combo
The Diamond filter/softener combo
The Diamond layers a full softening bed over activated carbon in one tank — one footprint, one valve, one install. Ships with a WS1 five-button control valve, 3/4 in × 1 in PVC connection elbows, and gravel underbedding.
Qualifying systems are backed by a lifetime limited manufacturer warranty; the written warranty states the specific coverage.
