Best Dual Tank Water Softener

Having hard water running at your house can become a costly problem for you. The dissolved minerals in the groundwater that flows through your home’s pipe combine with the heat, forming buildup and scale inside the pipe, harming your fixtures, appliances, and pipes. Rainwater is pure, without any minerals or even soft water. The rainwater then gathers minerals such as magnesium and calcium when it runs through the ground. Hard water is defined as water that has accumulated many minerals. Hard water isn’t bad for your body. However, it isn’t suitable for your house.

This is where water softener comes in. It treats hard water by eliminating the minerals that cause it using an ion-exchange method. The resin present within the system traps mineral ions that harm your home and cause water hardness and exchanges them for potassium and sodium ions.

From scale development, mineral deposits, and chalky films to dry hair and skin after showering, there are many common problems that water softener devices can prevent. The elimination of heavy minerals like magnesium, iron, and calcium from the water going into your point-of-use sites, RV, and your house, as well as improved drinking water and reduced water hardness, are all advantages of a water softener.

The most significant water softener’s function is either neutralizing the minerals present in the water or using an ion-exchange mechanism to remove heavy minerals from the water. In this way, the minerals won’t remain soluble and bind together in the water. We have made a list of the best water softeners you can choose from.

Dual Tank Water Softeners Buying Guide


What is a Dual Tank Whole House Water Softener?

Dual tank water softeners come with two cylinders that soften the water of your house, office, or restaurant separately. Tank 2 takes over when the first tank is being refilled. Since one tank replaces the other, these water softeners don’t pause during the cleaning process, which is why they provide softened water 24/7. It is helpful to continue operating throughout the day without any break, even after intense operations.


How Does a Dual Tank Water Softener Work?

After softening a specific amount of water, all water softeners must renew. They contain a resin bed within their tank that requires sodium replenishment after chilling a particular quantity of water.

Since the entire system closes down to clean itself, a single tank softener can’t deliver soft water on regeneration. While a twin tank softener comes with two tanks, if one of the tanks regenerates, another takes over.

Because of this, twin tank softeners can soften your water7 days a week and 24 hours a day, making them work more efficiently. 


Do I Need a Dual Tank Water Softener?

Many people are possibly looking for the idea of twin tank water softeners for their homes because they want to get rid of the hard water.

However, if you’re still undecided, let us clarify why you should get one now.

Anybody looking for high-end results should consider a dual-tank water softener. In other words, if you don’t want any hardness or any pollutants in the water, then the water softener is the best option for you out there.

If you’re not interested in drinking water that looks, tastes, and smells strange, then you must go for it.

Aside from that, these softeners are notable for their ability to function at all periods, no matter how difficult the situation is. You won’t even have to wait till the tank regenerates because the other tank would be at work during that time.

One tank can regenerate in a dual tank water softener while the other completes the task, which is impressive.

Dual Tank Water Softeners Advantages and Disadvantages

Advantages 

  • These water softeners can work 24 hours a day without any break because if one tank is regenerating, the other one works in its place. 
  • In most cases, dual tank devices are also more productive. They regenerate when necessary, depending on water use and capacity, with the least amount of salt and energy possible. The water quality of dual tank water softeners is more consistent.
  • The majority of single tank systems are set to renew at nighttime when they use less water. This results in improper salt and energy usage and water quality problems. On the other hand, dual tank water softener regeneration is more efficient and uses less energy and salt.

Disadvantages 

  • The initial cost of a dual tank water softener is much higher than that of a single tank water softener. 
  • Since it comes with two tanks, a dual water softener needs more space.
  • A dual tank water softener is not ideal for smaller places that do not require much water. 

What To Consider Before Purchase a Twin Tank Water Softener

Before buying a twin tank water softener, you must consider some things:

  • Flow Rate

This is the amount of water that the water softener device can produce every minute. This is how many gallons per minute there are in a minute. A water softener with a water flow rate of 7.4GPM to 22 GPM would be enough for smaller houses. The most crucial tip for restaurant owners and people who run small to medium-sized businesses is investing in a softener capable of delivering at least 22 GPM.

  • Capacity Needed

Before buying a water softener, look at the water hardness capacity it can handle. The more capacity it can handle, the better it is. 

  • Regeneration Technology

Most current water softeners contain metered regeneration, which is efficient since everyone desires metered regeneration. The method uses a mechanical water meter or an electronic sensor to evaluate your water usage. This enables the softener only to initiate a regeneration cycle when it is essential, such as when the resin is nearly exhausted or after a specified quantity of water has been consumed.

  • Budget

You must consider your budget before buying a water softener and decide according to your budget. But, don’t worry; there are many budget-friendly options available in the market. 

  • Maintenance

Before buying your water softener, don’t forget to look at its maintenance. It would be best to investigate things you may need to do daily to guarantee that your dual tank water softener is functional.

  • Certifications

Make sure that you buy a water softener certified by NSF or WQA. This would give you a 100% guarantee. 


How To Install a Dual Tank Water Softener?

  • Once you have decided where to install your dual tank water softener, you must shut off your water supply to plumb in the system. 
  • Once you are done with the plumbing, you have to install the tanks. Before installing the tanks, make sure you check their height and diameter because they should be the same.
  • After that, connect the joints close to the drain line, leaving at least 6 inches between these joints.
  • Ensure that the space beneath the brine tank is straight and tidy before placing it.
  • After that, fill the tank until it reaches a height of about an inch just above the grid plate. 
  • Connect the meter cord to the meter after connecting the valve to a power source.
