The Pentair PWS 1665 Water Softener is a fully automatic hard water softener that converts your incoming hard water into soft water using 185 litres of golden resin media the largest of Pentair's domestic softeners. It recharges itself with no manual intervention, holds 50kg of salt, and uses 28kg per recharge cycle.
What hard water is doing to your home. If your supply is borewell or municipal-hard, you already see it: soap that will not lather, scum on tiles and taps, white scaling on your shower and geyser, stiff laundry, dry skin and hair. That same scaling is building up inside your water heater, washing machine, and plumbing, shortening the life of every appliance water touches. A water softener stops the cause rather than treating the symptoms it removes the hardness minerals before the water reaches any of it.
What softening changes day to day. Softened water lathers properly, so you use less soap, shampoo, and detergent. Bathing feels different immediately no film on the skin, hair that rinses clean. Laundry comes out softer. Scum stops forming on bathroom surfaces, and the scaling that ruins geysers, washing machines, and taps stops accumulating.
The largest domestic Pentair sized for a big house. With 185 litres of resin, this handles the highest water demand in the Pentair domestic range: a large house, many bathrooms, or a household where several people draw water at once. Against the smaller models the PWS 1354 at 100L resin and the PWS 1465 at 150L the 1665 treats more water between regenerations, which matters when demand is high enough that a smaller unit would regenerate too frequently. Tell our team your household size, bathroom count, and water hardness and we will confirm which of the three fits; an undersized softener cycles constantly, an oversized one is money you did not need to spend.
Fully automatic nothing to operate. The programmable process valve runs the regeneration cycle automatically, so the resin recharges itself on schedule. You top up the salt; the system handles everything else.
