First Class Plumbing Backflow Services in Rancho Cucamonga

Occasionally, water can become reversed in your pipes, allowing soiled water to enter clean water. This results in immediate harm and poor sanitation for your family, making water unsafe for use and can result in a messy situation in your home or business. 

Having access to clean, usable water is a basic need for all people. Contaminated water can cause issues such as damage to your home and health concerns. A backflow valve can be installed to ensure that water is flowing safely in both directions and to avoid flooding mishaps from sewer backup. 

We offer backflow repair and backflow installation in Rancho Cucamonga. We can also provide maintenance on your existing backflow to ensure that it’s working effectively.

Plumbing FAQs

How does a backflow valve work?

Your plumbing system has two main goals: to bring clean water to your home and to carry contaminated water away from your home. With heavy rainfalls and overwhelming moisture, sewers can become backed up, resulting in soiled water backing up through the pipes, contaminating clean water and entering your home. 

A backflow valve ensures that sewer water only moves away from the home. It’ll minimize the chances of your home flooding from sewer waste or contaminated water entering your clean water stream.

What is a backflow preventer?

We offer backflow preventers in Rancho Cucamonga. Similar to backflow valves, backflow preventers work with clean water to ensure it only goes toward the home and doesn’t become wasted in the sewer pipes.

Do I need a backflow valve?

While a backflow valve is a good mechanism for all sewer systems, there are certain homes that are more susceptible to sewage backup. We especially recommend backflow valve and backflow preventer installation if: 

  • Your home has a basement
  • The ground floor of your home is less than 30cm above street level
