Frequently Asked Questions

How can I ensure that my family is drinking clean and safe water?

To ensure your family drinks clean and safe water in Austin, consider installing a home filtration system. While Austin’s water is generally safe, occasional treatment mistakes and the presence of chemicals can raise concerns. Home filtration systems offer peace of mind.

When it comes to installing a home water filter system, homeowners have two essential options:

  1. Under Counter Filtration: Easy installation under your sink.
  2. Whole Home Filtration: Filters all household water.

Radiant Plumbing and Air offers some of the industry’s best home filtration systems, and their customer service representatives can assist you in selecting the ideal system for your family. 

Clean, clear, and healthy water is not a luxury; it’s a basic human need. If you reside in Austin or San Antonio, understanding water quality is crucial. We are here to provide you with information on our water sources, their treatment processes, and ways to ensure your water is free from contaminants. 

A water filter doesn’t address water hardness in the same way a water softener does. Water filters are primarily designed to remove chemicals and contaminants such as pesticides, herbicides, chlorine, and biological organisms from your water supply. Some of these contaminants may be naturally occurring, while others could come from pollution sources in your area.

Water filters are highly effective at purifying water and ensuring its safety for consumption, but they are not specifically designed to eliminate minerals responsible for water hardness. The minerals primarily responsible for hardness, namely calcium and magnesium, typically pass through most standard water filters without significant removal.

To address hard water issues, a dedicated water softening system is recommended. Water softeners work by exchanging calcium and magnesium ions with sodium ions, effectively reducing water hardness. If you’re experiencing hard water problems, a water softener is a more suitable solution to improve the quality of your water by reducing mineral content.

To combat mineral buildup caused by hard water in your appliances, you have two primary options: prevention and reaction.

1. Prevention:

  • Whole House Water Softeners: Installing a whole-house water softener is a proactive approach to prevent mineral buildup. These systems work by exchanging calcium and magnesium ions with sodium ions, effectively reducing water hardness throughout your home.
  • RO System: A Reverse Osmosis (RO) system can also help by removing mineral particles from your water supply before they reach your appliances.

2. Reaction:

  • Natural Remedies: You can use natural remedies like white vinegar or lemon juice to tackle existing mineral buildup. The acids in these liquids can dissolve calcium and magnesium deposits. For example, you can pour white vinegar or lemon juice down sink or shower drains to dissolve lime buildup. Let it sit overnight and then rinse to remove the loosened deposits.

It’s essential to choose the approach that best suits your preferences and home needs. Prevention with water softeners or RO systems is proactive and can significantly reduce the occurrence of mineral buildup. On the other hand, using natural remedies can help address existing buildup but may require periodic maintenance. Keep in mind that standard water filter systems typically do not assist with reducing mineral buildup caused by hard water.

Installing a water filter system can be a DIY project in some cases, but it’s important to assess your skills and the complexity of the unit before deciding. Here’s some guidance to help you make the right choice:

DIY Installation:

  • You can consider installing a water filter system yourself if you have a good understanding of how plumbing systems work.
  • Basic plumbing skills, such as cutting into pipes and making connections, are essential for a successful DIY installation.
  • Simple water filter systems that do not require extensive modifications to your plumbing may be suitable for DIY installation.

Professional Installation:

  • If you lack plumbing knowledge or experience, or if the water filter system is complex, it’s advisable to hire a professional plumber.
  • Some water treatment systems, like whole-house filters or salt-based softeners, often involve cutting into your home’s plumbing system and may require connecting to the drainage system.
  • A licensed plumber has the expertise to ensure proper installation, reducing the risk of issues like cross-contamination, leaks, water damage, or prolonged periods without access to running water.

To avoid potential problems and ensure a reliable installation, it’s wise to hire a licensed and experienced plumber with the necessary tools and expertise. They can efficiently install your water filtering system, providing peace of mind that it will operate as expected.

To maintain the efficiency and effectiveness of your home water filtration system, there are several essential maintenance tasks to keep in mind:

1. Regular Filter Replacement:

  • The primary maintenance task for a water filtration system is to replace the filter regularly. Over time, filters accumulate captured sediment and debris, reducing their effectiveness.
  • The frequency of filter replacement depends on factors like the quality of your water and your water usage. Whole-home cartridge filters may last three to six months, while under-sink systems typically have a similar filter lifespan.
  • Avoid leaving an old filter in the system beyond its recommended lifespan, as it can allow sediment to flow past the filter, compromising water quality.

2. Inspection for Leaks and Clogs:

  • Periodically inspect your filtration system for any signs of leaks, clogs, or wear and tear. Changes in water pressure or water quality can be indicators of issues.
  • Conduct visual inspections to check for leaks, mold growth, or any visible damage to the system components.

3. Flushing the System:

  • If you haven’t used the filter system for a few days or longer, it’s a good practice to run the tap for a few minutes before using the filtered water. This helps flush out any stagnant water and ensures fresh and clean water supply.

4. Follow Manufacturer’s Guidelines:

  • Refer to the owner’s manual provided with your filtration system for specific maintenance instructions and recommendations.
  • Set reminders in your calendar or use the manufacturer’s recommended timeline for preventative maintenance tasks.

By adhering to a regular maintenance schedule and replacing filters as needed, you can ensure that your water filtration system continues to provide clean and safe water from your tap. Regular maintenance helps extend the lifespan of your system and ensures the quality of your drinking water for years to come.
