Duplex Water Softener System

A Duplex Water Softener consists of two vessels containing ion exchange resin, once the first column of resin has exhausted and goes into regeneration, the second column goes into service. This maintains soft water to service at all times.The main reason you might want or need a twin tank water softener is for consistent soft water 24/7. This cannot be done with a single tank system. Here's why: A water softener works by taking hard water and bringing it into the tank where there is a resin bed.A twin tank softener has two tanks which means that while one is regenerating, the other takes over. Twin tank softeners can soften water 24 hours a day because of this, making it more efficient than its single tank counterpart.The major disadvantage to softening water is the potential health risks for people that might be on low sodium diets. The exchange of hardness minerals for sodium adds 7.5 milligrams per quart for each gpg of hardness removed. In addition, calcium and magnesium are eliminated from the homeowner's diet.Water softeners can last 10 to 20 years, depending on the type and quality you buy. On average, a single tank electric water softener could last you up to 12 years, while a Kinetic system can last as many as 20 years. However, no appliance lasts forever.Households with three people or fewer typically need a softener with a grain capacity of around 20,000 units. Households with four or more people typically need a softener with a grain capacity of 30,000 units or more.
