Frequently Asked Questions

What is a home reverse osmosis (RO) system?

A home reverse osmosis (RO) system is a multi-stage water treatment process that effectively removes contaminants from unfiltered water, also known as feed water, by exerting pressure to push it through a semipermeable membrane. These residential RO systems typically incorporate at least three stages of treatment to reduce various types of contaminants. In the final stage, the RO membrane allows water to flow from the more concentrated side (containing more contaminants) to the less concentrated side (with fewer contaminants), resulting in clean drinking water. The clean water produced is called permeate, while the remaining concentrated water is known as waste or brine.

The process of a home reverse osmosis system involves several key components:

  1. Prefilter: This stage removes sediment and chlorine from the water before it is forced through the semipermeable membrane.
  2. RO Membrane: The semipermeable membrane effectively removes dissolved solids from the water.
  3. Postfilter: After passing through the RO membrane, the water undergoes additional filtration to further enhance its quality before reaching a dedicated faucet.

It’s essential to note that while reverse osmosis systems are highly effective at reducing various contaminants, they may not eliminate all bacteria and viruses. For water sourced from city treatment plants, microbiological safety is generally assured. However, bacteria could potentially grow on the RO membrane, posing a risk to the water supply. To address this concern and remove living organisms and viruses, UV disinfection is recommended.

Overall, reverse osmosis is a widely recognized and efficient water purification method, known for producing clean and great-tasting water. RO systems find applications in various settings, including whole-house filtration, faucets, aquariums, and restaurants, making them a versatile solution for improving water quality.

By the standards established by the U.S. Environmental Protection Agency (EPA) and the Texas Commission on Environmental Quality, Austin’s drinking water is deemed safe for consumption. However, if you’re like some Austin residents on Reddit, you may be fine just drinking it chilled from the fridge to make your water taste alright. 

If you’re seeking the best-tasting tap water in your home, a home reverse osmosis system (RO) can be an ideal solution. Reverse osmosis effectively removes various contaminants from the water, including chlorine, salt, PFAS, and dissolved solids such as arsenic and fluoride, by passing it through an RO membrane. Additionally, RO systems incorporate sediment and carbon filtration stages to address a wide range of contaminants.

Some of the contaminants removed by reverse osmosis include:

  • Fluoride
  • Salt
  • Sediment
  • Chlorine
  • Arsenic
  • VOCs (Volatile Organic Compounds)
  • PFAS (Per- and Polyfluoroalkyl Substances)
  • Microplastics
  • Herbicides and pesticides
  • Heavy metals
  • Many other contaminants

The effectiveness of RO systems in removing these contaminants is due to the multi-stage filtration process they employ. Here’s how it works:

  1. Prefiltration: The water initially undergoes prefiltration, which typically includes a carbon filter and a sediment filter. This stage removes sediment and chlorine, preventing potential clogging or damage to the RO membrane.
  2. Reverse Osmosis Membrane: The water is then passed through the RO membrane, which removes even microscopic dissolved particles.
  3. Storage Tank: The filtered water is stored in a tank until it is needed. The RO system continues to filter water until the storage tank is full and then automatically shuts off.
  4. Postfiltration: When you turn on your drinking water faucet, the water flows from the storage tank through another postfilter, which further refines the drinking water before it reaches your faucet.

In summary, while Austin’s tap water meets safety standards, homeowners seeking the highest water quality and taste often opt for a home reverse osmosis system to remove a wide range of contaminants and enhance the flavor of their drinking water.

Maintaining an RO system is relatively straightforward, and it typically involves routine filter replacements and, if applicable, prefilter changes. While a little preventative maintenance can go a long way, if you have a very complex whole house system, it’s a good idea to have it inspected annually to make sure there are no leaks or other problems. When you have your RO system professionally installed by experts like Radiant Plumbing and Air, you can expect minimal maintenance requirements. Here’s an overview of RO system maintenance:

  1. Filter Replacements: Most RO systems require regular filter replacements. The frequency of these replacements may vary based on factors like water quality and usage. Typically, there are multiple filters in the system, including prefilters, sediment filters, carbon filters, and the RO membrane. These filters need to be changed periodically to ensure the system continues to operate effectively.

  2. Prefilter Changes: If your RO system includes a prefilter, it may require additional filter changes. Prefilters are designed to remove sediment and chlorine, protecting the RO membrane from potential damage.

  3. Professional Installation: Having your RO system professionally installed by experienced plumbers ensures that the system is set up correctly from the start. Proper installation reduces the risk of issues and ensures optimal performance.

  4. Ongoing Maintenance Plans: The Radiant Care Club, is the most convenient way to keep your RO system in top condition. These plans often include scheduled appointments for filter replacements and system check-ups, ensuring that your home’s water quality remains excellent without the need for manual scheduling.

Overall, maintaining an RO system involves regular filter changes and, if necessary, prefilter replacements. Professional installation and maintenance plans can simplify the process and help ensure that your RO system continues to provide high-quality drinking water.

  1. Contact Your Water Supplier: Reach out to your local water utility provider or municipal water authority. They are mandated to provide annual Consumer Confidence Reports (CCR) that detail water quality in your area. You can typically find this valuable information on their official website or by contacting their customer service.

  3. Look for Signs of Contamination: Keep an eye out for telltale signs that might indicate water quality issues within your home. These typically include:
    • Unusual Taste: Detect any metallic, oily, or fishy taste in your water.
    • Chlorine Smell: Identify a strong chlorine odor, often added for disinfection purposes.
    • Sulfur Smell: Notice a rotten egg smell, potentially indicating the presence of sulfur.
    • Cloudy or Foamy Appearance: Monitor persistent cloudiness or foam in your water.
    • Low Water Pressure: Be aware of reduced water pressure, often due to clogged or corroded pipes.
    • Sediments or Discoloration: Inspect for blackening, dirt, or visible sediments in your sinks.
    • Government Advisories: Pay heed to advisories or boil water warnings issued by your local government.
