Have you considered backflow testing/repair/installation for your home? We all work hard to look after our families, including having safe drinking water that is as pure as possible within reach. It is a terrifying thought that the water we use outside of our homes could carry pollutants and microorganisms into our family’s drinking water, but there are affordable solutions.

Companies like Water Works Unlimited Inc provide systems for safer drinking water so that you can have the peace of mind you deserve.

What is Backflow?

The term ‘backflow’ describes how the water from outside irrigation, plumbing, or gardening systems enters the drinking water system on a property. Contaminants include:

  • bacteria,
  • fungi,
  • fertilizer,
  • pet waste and more

Backflow causes extremely unhealthy conditions for those consuming impure water without proper prevention. While foul odors or discoloration could sometimes indicate a problem, confirming your drinking water is safe is only possible through the professional backflow tester.

The benefits of testing your water are manifold, including:

  • a healthy water source for food preparation, cooking, and brushing your teeth
  • improved sanitation to combat toxins and other pollutants
  • peace of mind about the purity of the water your family is consuming

How We Perform Backflow Testing and Installation

We test water purity with special backflow tester equipment, as even microscopic particles affect the cleanliness of the water supply. Water Works Unlimited Inc recommends an annual backflow testing service as seasonal changes affect the landscape, water system, or maintenance requirements on your Raleigh, NC property.

Our standard water backflow testing process includes all external water systems, ensuring they meet regional and national health standards. Water Works Unlimited Inc makes backflow installation & testing services available at a time most convenient to you, including evenings and weekends.

What If the backflow Test Confirms a Contaminated Water Supply?

The presence of contaminants, even in low quantities, requires quick action. The problem could increase as contaminated backflow continues to leak into the drinking water, and it is essential to stop further contamination with reliable backflow prevention devices. These devices enforce a one-way flow of water through outdoor water systems, such as irrigation.

With the installation and testing thereafter, you can be sure that the water flowing from an irrigation system will not be able to return to your main water supply. Annual backflow testing/installation will ensure safe and clean drinking water, identifying problems early enough to safeguard your family’s health year-round.

Common Problems Arising from Irrigation Backflow

Most residential properties cross-connect permanently or temporarily with the public water system. These connections require a backflow preventer installation as standard safety measures for the public source. The primary reason is that sudden water pressure changes could easily drive contaminants back into the main system, causing widespread health problems.

There are two types of pressure changes:

Backpressure Backflow:

This problem occurs when downward pressure is suddenly greater than upward pressure. For example, when a pipe bursts.


This is a vacuum pressure problem. Think of sucking water through a straw for a sip but then releasing it before completing the action. The backwash from the brief vacuum pressure releases contaminants into the rest of the water, as when a fire hose pulls water from a hydrant for a short period and then releases it.

Once contaminants mingle with potable water, problems multiply. Without immediate filtering, the system redistributes poor-quality water to the public, commercial, and residential properties it feeds. Thankfully, there are ways to protect your Raleigh property from this surprisingly common occurrence.

FAQs - Backflow Testing/Repair/Installation Services

Backflow preventer installation and testing is a necessity for apartment and condominium buildings, restaurants, and other public places. We have shared some questions that are related to backflow installation. These may help you if you have some quires about backflow.

Yes. Raleigh’s residential homes benefit from these backflow prevention devices where the irrigation, sprinkler, or heating systems cross-connect to the public water system. Annual backflow testing should be sufficient.

Our certified backflow tester professionals complete irrigation backflow preventer testing to determine whether the water is flowing from outdoor water systems into residential or public drinking water supplies.

Our backflow testing, repair, and installation services use specialized equipment, state-certified and trained technicians, and delicate filters to test the water entering your home’s drinking supply.

Single-family residences are almost universally excluded from the backflow prevention requirement and thus the backflow test requirement as well. If all you own is a normal single-family home, then the answer is probably “no.” However, all commercial and industrial properties as well as multi-family residential properties typically are required to have backflow preventer installation, and thus they need to be tested once a year.

A common cause of low sprinkler water pressure is the backflow preventer device’s valves. If you see low water pressure in your sprinkler system but normal water pressure in your home, you may have a backflow preventer valve problem.
