Hard water causes mineral deposits inside the toilets due to the presence of calcium and magnesium ions. Professionals recommend putting the salts in the water-softening system installed in the house rather than placing it directly into the tank.
Can You Put Water Softener Salt in a Toilet Tank? You should not put water softener salt in a toilet tank directly because it can damage the flapper valve, corrode the tank components, insoluble in a small amount of water, and damage the plumbing system. Instead, you can add the salts in the brine tanks of the water softening system because these salts are designed to work inside this system.
People also use descaling products, water conditioners, and white vinegar instead of these salts to soften the water.
Water softener salts are designed to reduce the calcium and magnesium ions and exchange these ions with sodium to make the water soft.
Why you should not put water softener salt in a toilet tank directly?
It is better not to put the water-softening salts directly into the toilet tank because of the following reasons.
Damage to the flapper valve
The flapper is an essential toilet component, allowing the water to flow into the bowl to flush the waste.
Pouring the water-softening chemicals directly into the tank can cause the flapper valve and the seal to wear out.
These salts are designed to work inside the softening systems and can damage the components when they settle down to the bottom.
The damaged flapper cause abrupt water flow into the bowl and often leads the water to stop coming when you push the handle.
In addition, the seal around the flapper becomes loose or deteriorates over time if you add them more often inside the toilet.
Corrode the tank components
Different components inside the toilet tank, such as the fill valve, flush valve, chain, and overflow tube, work simultaneously to flush the waste down the drains.
These components can get corrode if you add the softeners frequently and directly inside the tank because of the chemicals used in salt manufacturing.
The rust and corrosion cause the components, and you have to face different problems while flushing the waste.
The purpose of adding the softeners in the tank vanishes, as it causes more damage instead of removing the rust and corrosion. Therefore, plumbers do not recommend adding them directly to the plumbing fixture.
Do not dissolve in a small quantity of tank water
The softener salts are designed to dissolve in a large quantity of water, and the water inside the tank is not sufficient to dissolve it properly.
They sit down at the bottom and cause damage to the components. Therefore, consult a professional plumber if you are facing a hard water problem instead of putting the chemicals directly into the tank.
It causes costly repairs because the salt particles accumulate at the inner base as the salts are insoluble in less water and affect the working and performance of the valve and flapper chain.
Damage to the plumbing system
It can damage the plumbing system and the drain pipes if you add these salts without a water-softening system.
The chemicals can attach to the copper pipes and cause a sticky layer inside the drain pipes, which causes clogging and blockage to the waste flow into the sewage.
The insoluble chemicals react with the metal pipes and cause cracks and holes, which leads to flooding and costly repairs.
It can affect the bacteria inside the septic system; however, adding the salts inside the softening system can provide different benefits and do not damage the plumbing system.
How can you use water softener salt in the toilet tank?
Professionals recommend adding water-softening salts inside the softening system installed in the house or the bathroom instead of pouring it directly into the fixtures.
The water softening system has a mineral tank that contains polystyrene beads. These beads carry a negative charge, and the whole mechanism works by exchanging the head ions with soft ions when you add the salt inside the brine tank.
Calcium and magnesium contain positive charges and stick with the negatively charged beads. A brine tank has softening salts and flushes the sodium and other soft ions.
The sodium ions also contain a positive charge but are not as strong as the calcium and magnesium, and go into the water, while the hard ions cling to the beads.
You can add them to the water-softening system once a month and examine the brine tank after a few days. The brine tank is separate from the mineral or bead one, which makes it easy to check the salt inside the system.
What can you use instead of water softener salts in the toilet tank?
You can use different products instead of salts inside the toilet tanks, and some of these products are listed below.
Descaling solution helps to remove the hard water stains and limescale buildup inside the toilet tank because they contain different chemicals that work on the stubborn stains.
The descaling products are available in hardware stores and are not much expensive. Add the quantity mentioned on the packing inside the plumbing fixture to avoid damage to the components.
Make sure that the product or solution is safe to use inside the toilets before applying it to the stains. Leave the descaling solution inside the fixture for 15-20 minutes, and flush it out.
Water conditioners remove the contaminants from the water like the salts do to make it soft. The water conditioning system is an alternative to the softening system using salts, but they work on different mechanisms.
They reduce the lead content inside the water and remove other elements, such as chlorine and volatile organic compounds.
This method does not use salts to remove the hard ions but alters the mineral ions’ structure to prevent the mineral deposits and scaling inside the plumbing fixture. However, some water conditioners use filtration to remove unwanted ions and make it less hard for the toilets.
Mango balls are the small devices used inside the toilet tank. They are an environment-friendly and non-chemical way to reduce the limescale and mineral deposits inside the plumbing fixture.
These balls use magnetic power to remove or crystallize calcium and magnesium ions, making them less hard.
It is a long-term water-softening solution and does not need much maintenance as other systems need.
You do not have to add different chemicals inside the plumbing fixture, which reduces the chances of damage to the components.
These balls treat the water magnetically and prevent the calcium carbonate ions and compounds from building on the surface. Instead, it sits at the tank bottom, and water circulates to magnetize the ions.
You can hand the balls with a string inside the tank and dip them deep into the water. Some brands offer 5-6 years of warranty for these magnoballs, and you can relax without worrying about the mineral deposits on the components and the bowl.
White vinegar is a natural descaler and water softener having no side effects on the toilet components because there is no toxic chemical inside it.
White vinegar not only softens the water but also kills mold and bacteria growing inside the plumbing fixture. In addition, it removes the calcium and magnesium buildup inside the toilet and cleans it properly to make it look new.
You can spray white vinegar daily inside the plumbing fixture, as it does not cause damage to the plumbing system and environment.
Why is it important to have soft water in your toilet tanks?
It is important to have soft water indie the toilet tanks because it will reduce the mineral deposits and limescale buildup on the toilet components.
The chances of clogging inside the drain pipes decrease because the soft water does not contain hard ions that cling to the drain pipes and block the way for the waste products to flow into the sewage.
The toilet can last many years and perform well under varying conditions if you install a water-softening system in the bathroom.
