General Electric pnmd45w Water Softener 45000 Grain

Product Description

The GENERAL ELECTRIC pnmd45w is a 45,000-grain capacity water softener with an integrated long-life charcoal filter and electronic demand-driven smart valve. It removes hardness up to 165 grains per gallon and reduces clear water iron up to 10 ppm. The unit runs on a 12V electronic control system powered by an included 120V AC adapter and communicates over built-in Wi-Fi for remote monitoring and control. Licensed plumbers install this system in residential or light-commercial applications where water quality, salt efficiency, and remote management are priorities. Salt efficiency is rated at 5,088 grains per pound of salt.

The pnmd45w is suited for indoor or outdoor installation and handles operating water pressures from 20 to 125 psi. The integrated charcoal filtration block — 0.31 cubic feet of media — provides chlorine reduction rated at up to 2,282,000 gallons at 0.50 ppm chlorine concentration, with scaled ratings down to 570,000 gallons at 2.0 ppm. The 1.5 cubic feet of standard mesh resin sits in a 10-inch diameter by 54-inch tall resin tank. The brine tank stores up to 325 pounds of salt and stands 37 inches tall by 17.5 inches wide and deep. Service flow rate is 9.5 gallons per minute at a 15 psi pressure drop.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes. Shut off the main water supply and depressurize the line before making any connections. The valve uses 1-inch NPT high-flow fittings; ensure the supply line is compatible before installation. Connect the unit to a grounded 120V AC outlet using the included power adapter, and complete Wi-Fi setup before commissioning to enable leak detection and remote shutoff features.
