Sterling Water Treatment PDIMX90 Twin Tank Water Softener, 90,000 Grain

The PDIMX90 is a 90,000 grain whole-house softener from the Sterling PDIMX series. A single control valve runs two tanks that take turns in service, so softened water is available 24 hours a day for households with steady, round-the-clock demand.

A meter watches water use and starts regeneration right away once the tank in service is exhausted, and the second tank picks up the load. The spent tank is then refreshed using softened water drawn from its partner. A bypass comes with the system for simple servicing.

This 90,000 grain model stands 76 in. tall, 34 in. wide and 62 in. long, and weighs 544 lb. Plan floor space and a solid base for both tanks before installation.
