Installation
Handy owners install many of these systems themselves with push-fit or threaded fittings. Backwashing filters and softeners also need a drain and an outlet. A plumber's cost varies with access and whether a bypass loop and drain line already exist, so get a quote with your exact model.
Dealer vs online
Local water treatment dealers often quote far more for comparable equipment, but include testing, installation and service. If you go online, budget for a test and an installer, and keep the return window in mind.
