Can a Water Softener Cause a Flood?

Some people experience a flood in their basement or another part of their home, and there is no apparent cause. The issue could be a problem with the water softener, and this can cause localized flooding and even problems with the septic system. There are a few reasons why this could occur and understanding them could help you to avoid this problem. Let’s examine this issue in greater detail, looking at diagnostic techniques and solutions you can try.Can a Water Softener Cause a Flood?

Are There Electrical Power Issues?

Many people believe that a lack of power to the unit over several days could cause flooding from the water softener. A lack of power by itself would not make the water softener overflow with water. The system usually works because of a clock control that will automatically backwash according to a scheduled timer. In order for an overflow to occur, there must be something else wrong, such as the control being left in regeneration mode or a lost connection to the drain pipe.

Is the Control System Damaged?

There are some exceptions involving electrical problems that could cause the system to overflow. The control equipment for your water softener could be damaged from various sources, such as a power outage, a lightning strike or an electrical storm. There could be other causes of damage to the control mechanisms, including corroded parts, jammed components, and leaks that could cause indirectly flooding. What often happens is that these problems cause the system to become stuck in a backwash mode. When there is a slow backwash or even a blocked water drain, the equipment could overflow and create localized flooding in your home.

What Happens When the System is Stuck in Regeneration Mode?

When the system is stuck in its regeneration mode, it can cause a lot of problems. Water will begin to flow into the drain continually, and this could last for days before it even get noticed. The flooding can be extensive; a water softener that is continually filling a building drain, especially one located on an upper floor, could easily back up. The effects are even more pronounced if the drain itself is backed up, blocked or slow draining.

Understanding How Your System Works:

If there has been a recent event that could have damaged your water softener controls and during the same period a slow or blocked drain occurred, these two events could be related. The water softener should not backup or overflow simply due to a lack of power, and any coincidence should be regarded as highly suspicious. If your system is stuck in a backwash cycle, it may be possible to manually turn the timer dial or reset the control system electrically. This should correct the problem, but take care and keep an eye on the system. It may be necessary to carry out a few manual backwash cycles to ensure that the system is stopping the regeneration cycle as intended. If the control system is damaged, it’s time to call out a local water treatment professional and get the system checked out.
