Buyer’s Guide for the Best Twin Tank Water Softener

There are some fundamental factors to consider when buying a water softener and it is important to carefully analyze those factors. Without doing this, you may end up wasting a lot of money on the wrong system.

Local Water Quality

Every household will have a varying degree of hard water going into their home. Some areas may be better than others, but it is always important to understand the quality of your water supply so that you can get the right product.

You can do this by completing simple, home-based tests for hard water or getting a report from the local authority. Once you understand how hard the water supply is, you can then shortlist a twin tank water softener that will cope with your water supply.

Water Consumption

Each household is different in terms of water usage. You may have a smaller household that spends a lot of time out, or a busy family home with lots of people using drinking water, washing, and showers. As a result, you need to do a bit of research on which softeners have the capacity to cope with your level of usage.

This is all about the grain capacity, with the average softeners coping with 48,000 – 64,000 per tank, and some going up to an impressive 90,000-grains. If you go for the wrong one, then it may not deliver the water you need and you will have annoying gaps in the water supply.

Budget

Never a fun topic to discuss but an important one! We all have our own budgets we need to stick to, so think about whether your budget will get you a system that does the job you need. It may be you can save money or equally, need to spend more to get one for your household requirements.

Flow rate

This refers to the soft water that the system can provide every minute, often referred to as Gallons per minute (GPM). Most households will copy with between 7 and 20 GPM, but you should check the performance levels claimed by manufacturers and compare this to customer reviews.

What is a Water Softener?

Water softeners are a household appliance that removes hard water deposits from your water supply. Water hardening can cause a variety of issues, including hard-water spots on dishes, skin irritation, and difficulties with home appliances such as faucets and showerheads. A water softener basically consists of a hard or salt tank that is connected to a brine tank. The salt tank contains hard water which is softened by caustic soda or liquid sodium carbonate. The liquid sodium carbonate acts as a detergent for removing the hard water from the hard tank. It deposits sodium on the surface of the hard minerals, which subsequently precipitates out of the solution, forming sludge in the bottom of the tank. The softened water then flows into the brine tank which contains salt, that is used to mix with hard water. The hard water then flows out of the softener into your home for use.

A water softener works by running hard water through special resin beads inside of the hard tank where hard minerals are removed from hard water. This causes sodium ions to replace the hard water minerals, which is a softer mix. This softened mix then flows into the brine tank that contains salt. The hard water mixes with sodium from the hard water softener and creates hard-water softener salt, which is drained from the brine tank, along with the flow of hard water back to your home for use. For more details on how water softeners work, Just follow our detailed guide.

What are the benefits of having a Twin Tank Water Softener?

There are some fantastic benefits to having such a system, including:

Protecting your skin and clothes

If hard water is left on the body for an extended period of time, hard water can cause hard water spots and hard water rings. These stains on the skin can be especially hard to remove because hard water is slightly acidic and it’s difficult to use substances that are also acidic to remove these marks.

Dealing with hard water also means that your clothes will have a harder time staying bright because hard water can dry out clothes, which reduces their ability to keep their bright colors.

Protecting your hair

Hard water can cause your hair to become brittle and get damaged, becoming matted and painful at times. It also affects the ability of soap to lather and work effectively, of all which can impact how well your hair is cared for. Having an effective water softener is important for your hair, body, and home so it makes so much sense to get one.

Protecting your appliances

The hard water is mixed with hard minerals like calcium and magnesium, which accumulate on hard-to-clean surfaces like soap scum and hard water stains. The hard water also leaves hard deposits on surfaces like showerheads, faucets, and appliance appliances over time. Water softeners are an excellent investment for anyone who lives in a hard water area. Unfortunately, hard water damages appliances, so this can be a substantial cost to either one’s wallet or the environment.

Frequently Ask Question:

What are Twin Tank Water Softeners?

Twin tank water softeners are sometimes known as dual tank systems and the fundamental characteristic is that they use two tanks instead of one to softener water. They work by taking turns to remove the hardness water causing minerals so that during a regeneration cycle, there is always one working to ensure a continuous supply of soft water.

They often have smart valves, such as the Fleck 9100 SXT to ensure maximum efficiency and control. For those wanting a permanent supply of soft water, these do a fantastic job of removing hard minerals including magnesium and calcium.

How does it work?

Firstly, the hard water flows through the water softener system and it is during this process that it goes through the resin tank. At this stage, the minerals that cause hard water get drawn to the resin and help to soften the water.

The resin becomes blocked up with hard minerals and at a certain point, the resin tank needs to regenerate so that it can start to soften the water supply again. As discussed above, twin tank softeners alternate this process so you never have to worry about hard water.

What is hard water?

Hard water is water that contains minerals in the form of hard deposits in drinking, bathing, and cooking water. These hard deposits can cause damage to plumbing and appliances. They can also build up in the human body and lead to problems with skin and hair. The hard deposits in hard water may also affect laundry detergents by causing clothes to be stiff or hard to wash.

The remedy for hard water is a water softener that uses salt to break down the mineral deposits in hard water so that it can’t cause any additional problems. A good example of such a device is a twin tank water softener which has two tanks: one for hard water and one for drinking-quality soft water. It’s important to install a hard-water tank close to hard water pipes and a soft-water tank close to drinking water pipes.

How do I choose the right one?

Please look at our buyer’s guide and the rest of the information on this page for help with this question. It is important to think about what individual requirements your household has, as well as future requirements such as maintenance and cost implications.
