So, you’ve figured out you have hard water (like 85 percent of homes in the US) and are researching water softeners. One of the first things you may want to consider, is the warranties offered by various manufacturers. You’ll notice there are a wide range of warranties in the water softening industry and these warranties certainly are NOT created equally.
Generally, the standard water softener warranty is for a one-year limit on parts (labor not included) and a 10-year warranty on the fiberglass resin tank and plastic brine tank.
But because softener tanks are usually not the issue when it comes to water softener problems and repairs (rather the valve and electronics)– most warranties end up falling short when you need them most.
