Questions & Answers
Does this water softener work for both well and city water?
Yes — this twin tank water softener can address hardness minerals from municipal and private well sources. When it comes to city water vs. well water, the biggest factor in determining hardness is the likelihood of your water source encountering calcium and magnesium — and how much. Although these minerals can be present in both water types, they’re especially common in well water. It’s also important to remember that water hardness varies depending on your geographic location, the source of your water and more.
Can one tank continue to operate if the other tank needs maintenance?
Yes. The dual design allows one tank to continue softening even while the other undergoes maintenance or regeneration. That means you’ll have a reliable, uninterrupted supply of soft water whenever you need it.
Does the Aquasential Smart HE Twin Softener system require more space than a single tank softener?
Because of its unique dual-tank design, this hard water softener system does require more space (see sizing chart above for more detail). This makes it ideal for homes with higher water usage. To find the type and size of softener that’s best for your needs, start with a free, in-home water test and consultation.
What are the advantages of a twin tank water softener over a single tank?
The biggest advantages of a twin tank softener are capacity and reliability; the two tanks enable the system to soften more water. That’s why this system is ideal for households with more taps, higher water usage or a larger number of people. Additionally, the twin tanks can operate independently, which means your softener is always working. Even if an issue arises or one tank needs to regenerate, the other continues softening water.
