Can you use Pool Salt in Water Softener? (Know Facts First)

Do you also want to know whether you can use Pool salt in your water softener?

Will pool salt work well for your water softener?

I will discuss the above questions in depth in this article and let you know the differences between pool and water softener salt.

Stick until the end of this article to know the issues of using pool salt, what I recommend, and more. 

Without further ado, let’s jump in!

Pool Salt Vs. Water Softener Salt 

Let’s understand what’s the main difference in Pool Salt and Water Softener Salt in layman terms.

Pool Salt 

Pool salt has the same purity as softener salt. The difference is in its texture which changes its properties. 

Pool salt is refined and extremely small salt. If used in a water softener, as described above, it would result in salty water instead of soft water. 

If used inside a water softener, pool water salt will shrink even further and will be left behind in the tank. This pool salt residue can form clumps in the water softener’s valve!

But if you were to form pool salt into pellets, it could be used in your water softener!

Softener Salt

Softener salt comes in the form of pellets or crystals. 

When used in a softener, even when they shrink, they don’t shrink enough to be left as a residue in the tank.

Water softeners need finer and non-dense salt to operate smoothly. 

Although, both softener salt and pool salt match on purity levels!

Does Pool Salt Work well in Water Softeners?

If you accidentally purchased pool salt instead of softener salt, it is safe for you to add small amounts of it to your water softener tank.

However, pool salt should not be substituted permanently for water softener salt; in addition to increasing the likelihood of salt bridge formation, pool salt will also prevent your softener from drawing brine effectively during regeneration. 

You can also damage your water softener if you use pool salt too much or regularly instead of water softener salt.

In short, a small amount of pool salt can be used alongside water softener salt in the brine tank without causing damage. Softeners should not be solely filled with pool salt.

Considering that pool salt treats pool water, you might assume it can soften it. 

There’s no truth to that. It is not recommended to use pool salt in a water softener. 

REMEMBER Adding only small amounts of pool salt to your water softener brine tank is safe. To lower swimming pools’ pH levels, pool salt is used.

What Happens if you Put Pool Salt in Water Softener?

When you put pool salt in your water softener, certain possibilities may happen or see the light. I have listed all of them below. 

They are – 

Chances of Salt Bridging – 

While pool salt is used in swimming pools, water-softening salts are designed specifically for softeners.

Using pool salt in your water softener system may result in mushing(when salt clogs the bottom of the tank and can’t dissolve) and bridges (when a hard layer of salt forms over the rest).

As well as bridging and salt mushing also blocks the brine draw pipe and prevents salt from dissolving into the water to form brine.

Reduce Brine Draw Efficiency  

Compared to water softener salt, pool salt is much finer. The flow of water can be hindered by the density of the pool salt grains, which are more closely stacked.

During the regeneration process, this can cause a problem during the brine draw cycle. Regeneration occurs when salt is drained from the salt tank, and freshwater is added to dilute the salt.

If the brine solution cannot be drawn out of the tank efficiently enough, the brine that is drawn might need to be diluted. This will leave the resin less effective at resupplying sodium ions.

Clogged Water Softener Valve

In the brine tank, water softener salt dissolves in water, resulting in a salty solution. In this process, salt particles become smaller – but the particles are originally quite big, so they are not drawn into the control valve of the water softener.

Swimming pool salt, on the other hand, is much smaller. In water softeners, fine pool salt is more likely to dissolve and build up inside the valves, clogging them over time.

This issue can usually be resolved by flushing the valve routinely, but in worst-case scenarios, the valve may need to be changed.

Resin Tank has an Excessive Amount of Salt

It is also possible for salt in the softener tank to be densely packed. This can result in an overload of salt in the resin because the water softener cannot draw in the salty water solution quickly enough.

Regeneration usually involves flushing out the salt water from the resin tank once sodium has been infused into the resin beads. As salt water is flushed out of the tank, the softener may continue to draw brine into the tank simultaneously.

Your soft water might taste unusually salty if there is too much salty brine in the resin tank.

What do We Recommend? 

You can safely use small amounts of swimming pool salt in your softener tank instead of softener salt as long as it is high-purity and free of dirt and debris.

A water softener will perform better if you use salt designed specifically for use in water softeners. This type of salt is unlikely to clog, bridge, or cause any other issues to your water softener.

You don’t need to panic if you accidentally add salt to your softening system. You don’t need to remove the salt; just wait until the pool salt level in the tank drops, then refill it with softener salt. You should be fine if pool salt does not dominate the tank.

I recommend using water softener salt instead of pool salt for your water softener unless you forget to or can’t.

FAQs

Can you use Morton Pool Salt in Water Softener? 

Yes, Morton pool salt can be used in water softening systems. Adding salt of a different variety to the tank of your softener could affect its performance and the quality of its softened water. 

Morton’s softener salt pellets are recommended instead of pool salt to avoid brine draw and clogging in your salt tank.

Can you Rock Salt in Water Softener? 

In a water softener, rock salt can be used; however, since it contains a high amount of water-insoluble matter, it should only be used by a consumer who is willing to perform routine brine tank filtration. 

This is usually required twice or three times a year for a typical home softener.

Conclusion

Wait! Read this before you go…

Pool salt is to be used to reduce the pH level of pools. Refrain from using it for water softener. 

If you use pool salt for your water softener, remember it’s not a permanent solution, as it will result in various possibilities of damage to your water softener. 

Now you know that using water softener salt is the correct choice for your water softener.
