What Is Backflow?

First, it is important to understand what backflow is. Backflow happens when water moves in a direction that it was not intended to move in. For example, hot water may drain out of your sink and then move into the cold water line. Most of the time when this happens, there’s a problem with the water pump that is affecting pressure.

It’s also possible for backflow problems to originate outside of your home. When this happens, a drain that was intended to move drain water may back up into the lines of your home. This usually happens if there are major blockages in main water lines that prevent water from draining out the way it needs to through the sewer system.

Reasons for Backflow

There are four common reasons that backflow can happen in your home. When you understand the reasons behind backflow, it’s easier to identify the problem early and get it addressed.

  1. Main water line is broken – If there’s a main waterline leading to your home that breaks, it may not be able to keep up with the demand. This can change the pressure in the system and lead to backflow problems.
  2. Long power outages – You probably don’t give much thought to the fact that water systems require electricity. Appliances like your hot water heater have pumps that move water. If there is a power outage, these pumps cannot work to move water through the system. Water may develop high levels of bacteria growth that can increase the likelihood of backflow.
  3. Plumbing upgrades – When you plan plumbing upgrades for your home, you need to consider that new fixtures and appliances may not be compatible with your older base plumbing system. There are many cases when you have to upgrade pipes and other components within your plumbing system as well. If the system is overloaded, it can lead to backflow problems.
  4. Pressure differences – The water pressure inside of your home needs to match the water pressure outside of your home to prevent backflow problems. If the two pressures don’t match, turning on the water at a sink, shower, or appliance can lead to a backflow issue.
