November 14, 2019

One of the most common problems you can encounter when using a water softener is overflow. Water overflow can create several problems in your home including structural damage, flooding and many other, and as a result, is a problem that will require immediate action. While there are other problems like low water pressure, overflow is more frequent in water softeners. If you feel you have low water pressure, you can check this article for information on how to verify and fix the problem. In the case of overflow, fixing the problem becomes a lot easier once you can identify the cause of the problem, as the solution will largely depend on the cause of the problem. Here are the common causes of water overflow and how to solve them in your water softener:

A malfunction in the brine valve assembly

The function of the brine valve assembly is to regulate the level of the brine water that flows through the water softener. The brine water is the hard water of water that is high in salt content, and as it flows into the water softener, is processed and treated to create softened water. In situations where excessive amounts of water flows into the water softener, it can cause the brine valve assembly to malfunction, which in turn leads to excessive amounts of water entering the salt tank, causing the water softener to overflow.


When this is the cause of your overflow problem, there is only one thing you can do to restore normal water flow to your water softener.  You will need to replace the brine valve assembly, as installing a new one will restore a normal flow pattern to your water flow, as it will give restore the regulatory function of the brine valve assembly, which will also prevent excess brine water from flowing into the salt tank, and will cut off an overflow that has already occurred.

A fault in the rotor valve:

The rotor valve acts as a navigational guide for the water flowing through the water softener. It is responsible for determining where water should flow in the water softener and as a result, directs water to the salt tank, the flusher basin and other locations in the softener for various reasons. If the rotor valve is damaged or clogged with particles that may have originated from the hard water, as it flows into the softener. When the rotor valve is impaired in any way, it ceases to function or functions inefficiently, causing water to flow randomly, and as such, can overload certain locations, such as the salt tank, causing overflowing.


If the rotor valve is clogged, all you will have to do is clean it, to restore the normal functionality of the valve. When this is done, the water flow will be restored to its usual pattern, and the overflow will cease. If the rotor valve is damaged, you will need to replace it with a new one to ensure that it restores functionality efficiently.

A busted salt tank

The salt tank is where all the hard water is usually treated and it usually holds a lot of water, depending on how much the home needs. If the tank is broken, due to excess water pressure or some other reason, this will cause the water softener to overflow. If such an event should occur, it may be best to turn off the water softener, until it is rectified.


If the salt tank is your problem, and it is broken, the only course of action will be to replace it. The salt tank is one of the most important components of the water softener and without it, the water softener is useless, so replacing it will be essential. If you are lucky, and it turns out that your salt tank is not broken, merely clogged, a simple cleaning with chemicals will fix your problem and have your water softener working properly, and free of overflow.

These solutions are easy and can be carried out by homeowners, but if you do not feel comfortable carrying out the repair yourself, you can always get a handyman to do them for you, but you can save yourself some money by diagnosing the problem, before calling a handyman.
