Different Types of Water Softener Valves and Their Everyday Impact

The type of valve will affect when your water softener regenerates its resin. Yes, it needs to be regenerated. As it keeps exchanging its sodium ions for the calcium and magnesium ions in the water, the resin becomes saturated. This is when regeneration comes into play. The brine (water + salt) in the tank will pass through the resin, this time replacing the magnesium and calcium ions with sodium ions. As a result, the resin is ready to soften water again.

There are 2 types of water softener valves: metered valves and timer-controlled valves. Each type of valve has its advantages and disadvantages.

Timer-controlled valves

You set your valve to a time interval, and the water softener will regenerate at that interval. For example, you choose a day of the week and a specific time, and the water softener will start automatically.

The main advantage is that once the valve is properly set (for a time when you are not using water), you will always have softened water available.

However, this solution has a disadvantage: even if you are not using water, for example when you are on vacation, your water softener will still regenerate at the scheduled time. This can increase your water and salt consumption.

In addition, if you use a lot of water over a short period, the resin will become saturated faster but will not be able to regenerate. Your water softener will then be ineffective until its next regeneration.

Metered valves

The operating principle is simple: the valve is set to a specific volume, and the water softener regenerates each time that volume has been used.

The main advantage is that the water softener will regenerate only when it needs to, rather than at set time intervals. As a result, you will save both water and salt. In addition, even if you occasionally use more water than usual, your water softener will regenerate at the right time so you never run out of softened water.

However, the disadvantage of this valve is that it may sometimes start regeneration during the day, when you need water. In this case, the water you use during regeneration will pass through the bypass and will therefore not be softened.
