How to Add Salt to a Water Softener
Brad Berdon • April 7, 2017

Salt is the only ongoing upkeep your water softener requires. You never have to change the salt; you simply add it as needed. Just like your car uses gas so the water softener uses salt. The amount of salt you use will be according to your amount of water consumption and how hard the water is at your home.

When Do I Add More Salt?

Salt can be added as much as you like. Some people prefer to add a bag a month just to make sure that their system has salt. Others, like me, fill it all the way to the top to reduce the frequency of servicing the system. But when you look in the salt pot and see only water it’s time to add a bag or two. The goal is to keep the salt above the water level so that the salt looks dry. This assures a maximum concentration of sodium and thus nice soft water.

Phase One-Full Salt Pot 

This is a salt pot that is completely full. I fill my salt pot all the way to the top like this one 2 to 3 time per year, that’s it. (note: individual results WILL vary. Water softeners use salt based on usage. So if your home uses more water the water softener will use more salt. If you use less water the water softener will use less salt.) The point made with this picture is that you dont have to add salt all the time or every month if you dont have the time to do so. Water softener salt pots usually hold between 200 and 300 pounds of salt which will give you some wiggle room when servicing.

Phase Two-Half Full Salt Pot

As the salt is consumed the salt level will become lower and lower. Eventually it will be low enough that the salt level will begin to submerge beneath the water like this. This is a good time to add some salt.

Phase Three-Empty Salt Pot             

At this phase the salt pot will be mostly empty with nothing but water inside. Salt should be added immediately to assure soft water for your home. If you run out of salt you run out of soft water.

Where Do I Buy Water Softener Salt In Jacksonville FL?

Salt is for sale almost everywhere. Publix, Walmart, Home Depot, Costco…etc. It’s called water softener salt or solar salt. You simply need Water Softener Solar Salt. Like anything there is usually a generic type brand and a name brand of salt on the shelf. At Publix you will find.

Publix stores in Jacksonville FL:

40 lbs Sun Gems  by Dixie Crystals            $4.99-$5.99

40 lbs Morton’s pure and natural               $5.99-$6.99

Does it matter if I use salt pellets or salt crystals?

No. It has no bearing on the function of the water softener as what form of salt is in the tank. Salt pellets or salt crystals is a preference. Some of the salt brands claim a longer water softener life if you use their brand; however that claim is very difficult to prove.

What about salt with rust remover in it?

Also on the shelf is a bag of salt that costs a little more that has a rust remover additive. This additive is a cleaner that helps the water softener resin stay clean when it is removing iron in addition to hard water. So this type of salt product is not needed on city water in Jacksonville FL. Our city water is very hard but it does not have iron in it so therefore you don’t need the rust remover salt. Rust remover salt is for water softeners installed on private well water.

Although there are water pipes near the water heater, they may not be the right pipe to connect a water softener system. You see, the right pipe to connect a water softener to is the main supply pipe or service pipe. Connecting a water softener to the service pipe assures 100% soft water on both the cold and hot side of the plumbing system. Can the service pipe be located next to the water heater? Sometimes yes, but more often no. If your home has a water softener loop this means the service pipe is pre plumbed to a convenient location in the garage, often times near the water heater. If your home does not have the loop then you will have to located your main supply pipe to determine placement. Where is the Main Supply, or Service Pipe, at my house? To locate your service pipe the first thing you need to determine is where your water meter (out by the street) is located. Is it on the garage side or the non garage side of your home? In Jacksonville the water meter is a concrete box with the letters JEA on it. In St Johns/ St Augustine it's usually a plastic meter box with a bright blue lid. Standing out at the meter near the street, look up at your home. The plumber had to connect water to your home from this meter location. Usually, the path of least resistance is used to make this connection. 90% of the time the water enters the home on the same side of the home that the water meter is located. The point that the supply pipe enters your home (POE Point Of Entry) should be marked by a green plastic circle shaped lid. However, sometimes it gets buried under years of landscaping and mulch and sometimes it's not marked at all. Once the POE is located you can now determine where the water softener will be installed.

If a water softener system stops using salt you will not get soft water. The most common reason a water softener stops using salt is due to the formation of a "Salt Bridge". A Salt Bridge is a clump of salt that has been fused together due to moisture that's spans entire diameter of the salt tank. This clumped salt resembles concrete and is very hard to break up. Consequently, the salt bridge prevents the salt on top from coming in contact with the water beneath it. That is why we call it a Salt Bridge. How is a Salt Bridge formed? A salt bridge is formed when the dry salt is exposed to moisture. Moisture causes the once granular salt crystal or pellet to merge into one giant clump of salt. By chance if it makes it from one side of the tank to the other side a bridge is formed. Once the bridge of salt is formed the salt level will no longer go down. At this point the salt bridge needs to be broken up. How to remove a salt bridge. I hope you ate your Wheaties because removing a salt bridge can be intense. Once the salt has fused together the consistency resembles concrete. So, breaking it up will take some effort. Method 1. The Rubber Mallet First. Use a rubber mallet and gently tap/hit the side of the salt tank all around it. Next, grab the rim of the salt tank and give it a good shake. Note, the salt tank is hundreds of pounds so shaking it may be difficult for some people. Method 2. The Broom Stick If Method 1 did not work it's time to move onto method 2. Brut force and a firm tool. By using a broom stick, a shovel, or an iron rod, you will attack the salt bridge until you succeed. Start by removing all the loose salt from the salt tank into a bucket or onto a drop cloth. Once you see the bridge start pounding trying to locate a weak area of the bridge. Keep working the weak area until you make it all the way through the bridge. It might be a few inches to a foot thick. Then keep working the salt bridge until the entire bridge breaks up and falls down inside the salt tank. Remember, the greater the obstacle the greater the glory when you overcome it. Method 3. The Water Method If you cannot physically break through the salt bridge then you may have to add water. To do this, use a hose to spray water into one dedicated spot while continuing to work the area with a broom stick. The salt bridge will quickly give way however your salt tank will have a lot of water left in it. Stop spraying water and thoroughly break up the remaining clumps of salt. From here, place the system into regeneration either immediate (right now) or delayed (tonight at 2am). Different models of water softeners will have different configured buttons and programming. You may have to consult your owners manual. Note, adding water is an effective way at breaking up a salt bridge but all the salt gets wet during the process. Wet salt will have the potential to bridge again. If you have to use the water method, break up the salt daily to avoid another salt bridge. How to Avoid a Salt Bridge Preventing a salt bridge in a water softener system in Jacksonville FL is easy. Either before you refill a low/empty salt tank, or if you are filing the tank for the first time simply place two pieces of scrap pipe in the shape of an X. As the salt level lowers it falls around the pipes and avoids bridging. This is our standard practice when installing our water softener systems in Jacksonville FL.
