Cypress Backflow Prevention & Testing

Effectively Protecting Your Water Source

Your plumbing system is set up so that you have access to clean water and to ensure that dirty, contaminated water flows safely out of your home or business. Backflow occurs when dirty water flows in the opposite direction, and it is most often caused by improper pressure differences. 

The only way to prevent a plumbing catastrophe is with a working backflow prevention device. Although city laws protect you to some degree, even municipal systems can fail. At Belknap Plumbing Systems, we can ensure your plumbing system is safe and secure, giving you the peace of mind you deserve.


With over decades of experience, you can rely on our Cypress plumbers to get the job done right. Give us a call at (832) 990-9700 for a free cost estimate. 


What Is Backflow Prevention?

The purpose of a backflow prevention device is to keep pollution and contaminants from entering your water due to system backflow. It does this by allowing water to enter the home but blocks any water that is flowing from the opposite direction. A backflow prevention device is an essential component of your water supply system.

If you have noticed that your water pressure is lower, your water smells bad, or there are visible contaminants in the water, you should seek professional help from an experienced plumber as you may have a backflow issue.

Our Cypress Backflow Prevention Services Include:

  • Annual testing
  • Installation of new systems
  • Repair of backflow systems
  • Replacement of backflow preventers

How to Maintain Your Backflow Prevention System

Regular maintenance is key to keeping your backflow prevention device in top shape. Follow these steps to ensure its longevity:

  • Schedule Annual Testing: Many local regulations require yearly backflow testing to ensure compliance.
  • Inspect for Leaks: Check for visible leaks or corrosion around your backflow preventer.
  • Avoid DIY Repairs: These systems require expert handling—always hire a licensed plumber.
  • Monitor Water Pressure: Sudden changes in pressure may indicate a failing preventer.
  • Know the Regulations: Backflow prevention laws vary by location; staying informed helps you avoid fines.

By following these maintenance steps, you can prevent unexpected plumbing issues and ensure a safe water supply.

Can weather conditions in Cypress affect backflow prevention devices?

Yes, extreme weather, such as heavy rainfall or sudden freezes, can impact backflow preventers. Flooding may introduce debris into your system, while freezing temperatures can cause cracks or leaks. Regular maintenance and seasonal inspections can help prevent weather-related damage.

How do I know if my backflow prevention device needs repairs?

Signs that your backflow preventer needs repair include water discoloration, a drop in water pressure, or an unusual odor coming from your taps. If you notice any of these issues, it’s important to schedule an inspection as soon as possible to prevent potential contamination.
