Water Treatment System Repair Cost

Water treatment system repair costs range from $150 to $800. An inspection alone costs $50 to $150. Typically, a home repair visit has a minimum service fee of $100, and an inspection is often included in this price.

Water Distillers

Repairing a water distiller varies by the machine and the type of repair needed. You can hire a plumber locally or ship it in to have it fixed by a factory-certified technician. Distillers often run for 20 years or more without the need for repairs.

Whole-House Filter Systems

Repairing a whole-house water filtration system costs anywhere from $50 to $800. Your final bill will depend more on the problem, how far you live from the repair service, and brand pricing differences. IF your budget looks like it might hit $800 or more, you might consider replacing the system.

Hoses and other parts costs: $5-$50
Filters cost: $50-$300
Leak repairs cost: $150-$300

Under Sink Filters

Under sink filter systems cost $150 to $300 to repair. Besides regular maintenance and filter replacement, repairs are rare. Since under sink systems cost $50 to $500, replacement rather than repair is often a better solution.

However, you’ll always pay a service call fee of $300 on average. Since reverse osmosis systems cost $500 to $2,800 on average, it’s usually cheaper to repair rather than replace.

DIY vs. Professional Water Treatment Service

You might consider fixing your water softener or treatment system for some regular repairs. Things like replacing filters, filling salt and cleaning the machine make excellent weekend projects. However, you’ll want to know exactly what you’re doing since done incorrectly, you may ruin your system, cause leaks or hurt your plumbing. It’s best to leave repairs involving replacing parts or working with plumbing to licensed professionals.

“If you want to save money on maintaining your system but are nervous about it, you can always hire a plumber to inspect the system and ask a lot of questions or hire them to perform maintenance the first time and watch how they perform the work,” says Jeff Botelho, Angi Expert Review Board member and Massachusetts-licensed journeyman plumber. “Some tasks are best left to the pros, but it’s a good idea to get comfortable with the parts of your system that you can maintain yourself.”

Find a local plumber or water softener repair company near you for quotes. Not only will you have peace of mind knowing they complete everything correctly, but you’ll usually have a warranty on parts and labor.
