Understanding Reverse Osmosis Systems and Common Fridge Water Line Issues
One of the most common calls we get at Phoenix Appliance Repair starts the same way:
🧊 “My fridge isn't dispensing water or making ice—what’s wrong with it?”
In many cases, the refrigerator isn’t broken at all.
A recent service visit in Gilbert, Arizona, revealed exactly that. A couple had just moved into their new home and thought the fridge was failing. But when our technician inspected it, we found that the water line had been previously connected to a reverse osmosis (RO) system—and the former homeowner had taken that system with them when they moved out. The water valve was shut off, the RO filter was gone, and the fridge simply didn’t have a working water supply.
✅ Diagnosis: The refrigerator was working exactly as designed—it just didn’t have access to water.
If you’ve searched “should I connect my refrigerator to RO water?” or “pros and cons of reverse osmosis for fridge,” here’s what you need to know.
Many Arizona homeowners choose reverse osmosis systems for fridge water dispensers due to the extra purification they offer. But there are important benefits and downsides to consider before installing—or troubleshooting—an RO system.
1. Exceptional Water Purity
RO systems filter out a wider range of contaminants compared to regular refrigerator filters—including heavy metals, chlorine, PFAS, bacteria, and viruses.
2. Improved Taste and Clarity
RO water is often described as cleaner, crisper, and better-tasting. It’s free from chlorine or mineral aftertastes, and it makes clear ice cubes that don’t leave residue.
3. Whole-Kitchen Convenience
Many systems can be plumbed directly into your refrigerator, supplying purified water and ice straight from the dispenser.
1. Higher Installation Cost
RO systems are more expensive than simple in-fridge filters or water lines and require professional installation in most cases.
2. Water Waste
Most reverse osmosis systems discharge some wastewater during the filtration process, making them less water-efficient than basic inline filters.
3. Room Temperature Output
Water that comes from the RO storage tank may be room temperature when it first reaches your fridge. However, once inside the fridge, it gets chilled and can be dispensed cold or combined with ice.
Before calling a technician, check for these common culprits:
If you’ve Googled “fridge stopped making ice after move” or “no water from fridge dispenser after installing RO system,” this might be your issue.
If your refrigerator isn’t dispensing water or making ice, don’t panic. There’s a good chance the problem isn’t mechanical—it might be installation-related.
