Backflow Testing Services

Backflow Testing Services in Greenwood, IN

Normally, clean water flows into your home to provide water for drinking, showers, laundry, waste removal, and other daily tasks. Used water will then flow away from your home via your sewer pipes. However, backflow can occur if there is a reversal in the normal flow of water, allowing contaminated water to flow back into your home’s plumbing system.

This can pose a serious health risk, as the contaminated water can contain harmful bacteria, chemicals, and other hazards that can infiltrate your clean water supply and lead to serious illness and disease.

Johnson Heating | Cooling | Plumbing understands the severity of backflow, which is why we provide backflow testing services in Greenwood, IN. Contact us today to learn more or to schedule services.

How Does Backflow Occur?

Backflow typically occurs due to a sudden change in water pressure. This can be caused by a variety of factors, including:

Water Main Breaks or Repairs

If a local water main breaks or requires repairs in the local area, you may experience a drop in water pressure that can lead to backflow.

High Demand for Water

High demand for water in your local area, such as a fire hydrant opened to help extinguish a fire, can cause a sudden drop in water pressure and result in backflow.

Malfunctions in Plumbing Fixtures

Malfunctions in plumbing fixtures, such as pumps or valves, can cause a sudden increase in water pressure.


Cross-connections between potable water supplies and non-potable sources, such as irrigation systems or swimming pools, can cause backflow.

If you suspect that your home is experiencing issues related to backflow, get in contact with Johnson to schedule backflow testing in Greenwood, IN.

When to Schedule Backflow Testing

Thankfully, your home’s current backflow preventer can easily be tested. This can ultimately determine if your home’s water supply is still safe for drinking and other common household uses.

If you recognize any of the following potential signs of backflow in your home’s water, be sure to contact Johnson immediately to have your water tested:

  • Water discoloration
  • Strange, foul odors coming from your water
  • Particles floating in your water
  • Slow or interrupted flow of water
  • Leaks coming from toilets or sinks

With backflow, acting fast is crucial in limiting the damage and protecting your home. For fast and reliable backflow testing services in Greenwood, IN, get in contact with the team at Johnson today.

How Backflow Preventers Can Prevent Backflow

Backflow preventers are designed to keep contaminated water from reversing its flow and reentering your home.

These devices work by creating a physical barrier that prevents backflow from occurring, ensuring that the water flows in one direction only and protecting your potable water supply from contamination. 

To ensure the continued success and protection provided by backflow prevention devices, they must be regularly inspected and tested. Should any issues arise, having the preventer repaired or replaced can help to protect your home from backflow contamination.
