Buying Guide for Dual Tank Water Softener
Before purchasing a twin tank water softener, keep the following considerations in mind.
Water Consumption: You should first determine the amount of water usage in your house daily. After that, you should go for the most appropriate size that can meet your daily household water needs.
Flow Rate: The flow rate is another critical buying factor that you must consider. You should go for higher flow rates to ensure a bigger supply per minute. However, make sure that the flow rate is not too high as compared to the capacity of your pipes and appliances as it can damage them.
Regeneration Technology: There are different types of regeneration technologies available in water softeners. Timed water regeneration and metered regeneration are the most common types. We recommend you consider metered regeneration which will automatically regenerate.
Maintenance: Regular maintenance is also very important to extend the lifespan of a water softener. You should at least clean the brine tank at least once a month. Apart from this routine maintenance, periodic maintenance depends upon the manufacturer’s guidelines. You should check the user manual carefully to know more about the maintenance costs.
Certifications: Third-party certifications are also a plus point to judge the quality of any water softener. When a water softener contains third-party certifications, it has already gone through vigorous testing. You can check NSF/ANSI 44 and NSF/ANSI 372 certifications for more accurate information about the quality.

Why Would You Need a Dual Tank Water Softener?
A dual tank water softener is the only option left for anyone looking for more results, especially for the continuous soft water supply. In a twin tank softening unit, you don’t have to wait for so long to wait for the water regeneration. Moreover, it also eliminates the majority of the contaminants in the water and improves its taste. Apart from everything, two tank water softeners are ideal for commercial use or household of 5-10 people without causing any interruption in the soft water supply.
How Does a Dual Tank Water Softener Works?
The working of a dual water softener is no different from a single tank water softener. The only difference is the dual tank which is kept as a backup to meet the needs of large households. When the water comes from the plumbing system to the tank, it passes through a brine tank that includes salt or filters to clean the water from excessive minerals. The second most critical step is regeneration; when the tanks clean themselves during the regeneration process, the other backup tank continues the soft water supply. Due to its double tank, it offers 24/7 operation without any interruption or delay.

Advantages and Disadvantages of Dual Tank Water Softeners
These are the following advantages and disadvantages of double tank water softener systems.
Uninterrupted water supply: Due to dual tanks, the twin tank water softeners ensure a 24/7 water supply even during regeneration.
Efficient cleaning: As we all know, each brine tank regenerates itself more efficiently, resulting in efficient cleaning and better taste.
Durability: Dual tanks are used in these water softeners, and the load is divided equally. Due to this, the tanks tend to last longer than single tank water softeners.
Less Maintenance Cost: As we all know, 2 tank water softeners prevent damage to the plumbing system, resulting in less maintenance cost.
Higher Cost: The initial cost of a dual tank water softener is quite higher than single tank water softeners. You can expect a price difference of 10% to 100% between dual tank water softeners and single tank water softeners.
Requires more space: A dual tank softener usually requires more space for installation. These types of water softeners cannot adjust in small areas.
Water Softener Dual Tank vs Single
If there is any confusion in your mind regarding single tank and dual tank water softeners, then you should carefully read this brief guide. Here are some key differences between single and dual tank water softeners.
Tank Size: A dual tank water softener contains two tanks, making them more efficient and convenient. On the other hand, double tank water softeners also require more space for installation. You can go for single-tank water softeners if you don’t have extra space where you can install a twin tank water softener.
Water Softening Capability: There is a specific filtering limit in most single-tank water softeners. Once the limit reaches, the water softener must stop the work until the regeneration is completed. On the other hand, twin tank water softeners can continue soft water supply during the regeneration process because of their backup tank.
Water Flow: A dual tank water softener offers a water flow from 10 to 20 GPM. On the other hand, this limit is 12 GPM for single tank water softeners. So, the water flow is another key difference between the single tank and dual tank water softeners.
Durability: We all know that single tank water softeners quickly run out of brine capacity, which can cost you more money. On the other hand, a dual tank unit can last longer, and the water regeneration done with soft water results in fewer problems.
