Should you buy or lease a water softener? In the short run, leasing is often the most attractive option because there are no significant upfront costs. Depending on the level of service and materials the company offers, you can pay from $15 to $50 per month or more on a lease. If you buy, you will pay about $150 per year for materials. And, of course, you’ll have to pay for the unit. Depending upon the features, prices range from about $400 to $2,500 or more.

Get at least two quotes. And be sure the quotes are based on exactly the same type of considerations: regeneration cycle, type of controls, level of service, and, of course, warranty on both the control valve and the resin tank.

It is usually best to work with an established company. That way, you’ll get a quality product backed by a company that is likely to remain in business for a while.

Find out whether you will need a plumber for installation or whether a special factory serviceperson is required to do the job. And be sure to pay attention to the month fee of maintaining the softerner.

Also look for certification. NSF International is an independent testing organization that tests and certifies water-treatment products. The water industry’s trade organization, the Water Quality Association, also certifies equipment, so look for the WQA Gold Seal. Although neither of these certifications guarantees performance, they signify that the equipment has successfully passed testing for industry standards and the manufacturer’s claims have been validated— an important step toward ensuring that the unit you buy or lease will offer years of trouble-free service.
