Excessive RO Discharge Troubleshooting: Why Your Reverse Osmosis System Keeps Draining

Homeowner troubleshooting excessive water discharge from an under-sink reverse osmosis system

Excessive RO Discharge Troubleshooting: Reverse osmosis systems naturally produce some wastewater during the filtration process. While your RO system is making purified water, it sends concentrated water containing rejected contaminants to the drain. This means that some drain flow is completely normal. However, continuous or excessive RO discharge can indicate a problem, especially when the […]

How to Sanitize a Reverse Osmosis System: Complete RO Sanitization Guide

Sanitizing an under-sink reverse osmosis water filtration system during routine maintenance

How to Sanitize a Reverse Osmosis System: Regularly sanitizing your reverse osmosis system is an important part of maintaining a clean and properly functioning drinking-water system. Over time, bacteria and other microorganisms can potentially accumulate in components such as the storage tank, filter housings, tubing, and faucet. Replacing filters on schedule is essential, but filter […]

Reverse Osmosis Membrane Replacement: When and How to Replace Your RO Membrane

Replacing a reverse osmosis membrane in an under-sink RO water filtration system

Reverse Osmosis Membrane Replacement: The reverse osmosis membrane is one of the most important components in an RO water filtration system. While sediment and carbon filters typically require regular replacement every several months, the RO membrane is designed to last much longer. However, an RO membrane does not last forever. Over time, dissolved minerals, sediment, […]

Reverse Osmosis Filter Replacement Schedule: When to Change RO Filters and Membranes

Reverse osmosis filters and membrane arranged for a scheduled under-sink RO system replacement

Reverse Osmosis Filter Replacement Schedule: Regular filter replacement is one of the most important parts of maintaining a reverse osmosis (RO) system. Your sediment filters, carbon filters, post-filters, and RO membrane all have different jobs—and they may also have different replacement schedules. Waiting too long to replace filters can affect water flow, system performance, taste, […]
