Can A Water Softener Tank Explode?

Yes! A water softener can explode when under too much pressure or a leak in the whole house water line,too much potassium chloride being added to the tank, if the water softener is too old and a cracked tank. If a water softener explodes, it releases a large quantity of water and sodium chloride into the surrounding air.

Water softeners can also explode because of a cracked tank, which occurs when the steel pipes inside the water softener corrode or rust over time. 

Water softeners do not explode on purpose or at any single moment. The process of exploding is gradual.

A water softener’s tank will be fine most of the time, but after many years of use, it could be cracked from age or pressure, which could cause it to explode–usually in small bursts instead of one huge one.

If your household water has large amounts of iron in it, there is a higher chance that when the water comes out of the softener, it will be rusty, increasing the chances of a tank exploding.

Can You Have A Water Softener Without A Drain?

A water softener is a mechanical device that uses chemicals, minerals, and electricity to remove hard water from water systems.

It also uses an ion exchanger to recombine the salt ions with the water ions. These two devices have an important role in getting rid of hard water.

To paraphrase, a neutralizing agent and a resin are used. The ion exchange membrane absorbs positively charged sodium ions and releases negatively charged magnesium ions into its surroundings.

Can A Water Softener Tank Explode?

Yes! You can have a water softener without a drain, and it’s a lot cheaper.

In the olden days, doing that would have been impossible because water softeners rely on a waste pump to remove the softened water from your home.

But today, modern technology has created great new inventions that enable its proper functioning without any drains.

There are two categories: water softeners with an on-demand pump and those with an automatic pump.

While the first category helps you save money, it has the drawback of requiring an electrician to install a pump directly into your home’s electrical panel.

You will have to have a PVC pipe installed in your home’s drainage system that leads to the built-in pump.

The best thing about this water softener is that you can install it without any modifications being made to your plumbing or electrical system.

It will, therefore, work with your present plumbing and electrical system, assuring you of a smooth water supply.

While the second category of water softeners doesn’t require any direct pump installation in your home, it does have its drawbacks.

This type requires an inlet valve to be installed into your home’s drainage system to channel the wastewater from the home’s plumbing system into a storage tank.

Every time water is used, the soft water stored in the tank is drained into the home’s plumbing system.

It also requires a drain line to be installed to the waste tank, which requires that you first sink a pit in your lawn.

The second type of water softener has been around for about thirty years, and it works very well because of its simplicity.

It does require an electrician to install a pump directly into your home’s electrical panel. This pump is on standby all the time, and it will only turn on when water is used in your home for any purpose.

The great advantage of this type of water softener is that it uses a large capacity tank that can hold up to 850 gallons of water.

You don’t have to use the drain line regularly. Its simple workings also mean that you will never imagine how effective it can be.

Do Water Softeners Have A Drain Line?

Yes! Most water softeners need two drain tubes to release the saltwater brine and a second to release any excess water.

This allows the water softener to function properly, but it also means that your plumbing will have clogs if the tubes collect too much sediment or debris.

The drain needs to be sized correctly for both pipes draining into it. Just like regular plumbing, you should use a T-junction for both pipes not to back up into your home.

The incoming line should be 3/4 inch, while the outbound lines should be 1/2 inch.

Ensure that the drain runs to a window or a utility sink to make maintenance and repair easier.

If you have a water heater installed nearby, shorter drain lines can heat the water as it runs through the pipes.

If you have never tried running hot water through your plumbing system before, you will be surprised at how warm the water is when it leaves the water heater and goes through the pipes.

The drain line should also be sloped downward by 1/8 inch per foot in order not to cause drainage problems in the future. A good rule of thumb is an 8-inch drop over 10 feet of length.

You can avoid plumbing issues with the right equipment and plumbing understanding.

Is The Water In The Water Softener Tank Safe?

Yes! Water in the water softener tank is safe to drink. The water softener unit removes the hard minerals from the water, so it’s safe to drink regardless of how it’s delivered.

Some locations add minerals back, so ask your water company if you’re in doubt. 

A water softener works by altering calcium and magnesium dissolved in the water with sodium or potassium hydroxides.

Caustic soda (NaOH) is also used to help remove hardness minerals from the source water before entering the unit.

This type of treatment is necessary because hard water contains high amounts of calcium and magnesium that can stress plumbing systems when they dissolve into the drinking water.

The sodium hydroxide and potassium hydroxide are added to the water softener tank and dissolved into the water.

As water is used throughout your home, it will pass through one or more tanks full of softened water, depending on the unit you have installed.

This ongoing process only stops when the incoming hard water uses all of the sodium and potassium hydroxides.

Once the sodium and potassium hydroxide levels are depleted, the excess water and any remaining dissolved solids are discharged from the tank into your home’s sewer line.

You should never dispose of hard water treatment chemicals down your drain.

Can A Water Softener Cause The Air In Pipes?

Yes! If you notice that your pipes are making sounds or knocking, or if water pressure drops when running the water, it could be a sign of air in the pipes. 

If you boast a water softener and notice these symptoms, the hard minerals (typically calcium) in the softened water may be deposited on valves, causing leaks and excess wear.

To help fix this problem, install an air stripper to remove any excess mineral deposits from your softened water before it reaches your appliances.

If you have hard water, you should consider installing an under-the-sink water softener to remove the minerals and replace them with sodium.

Mechanism: Water flowing through pipes isn’t always smooth and round; sometimes, it gets a little bumpy because of mineral deposits called scale.

Can A Water Softener Tank Explode?

Scale is a non-magnetic residue left after calcium and magnesium salts are removed from the water. For example, only very hard water (fluoridated water) will leave any residue.

Water’s surface tension causes it to hang up on the scale and create a layer of ceramic coating between the water molecules.

This ceramic coating makes the water look clean and clear (most of the time) but can also make pipes rough and bumpy, sometimes breaking pipes.

Can A Water Softener Overflow?

Yes! It is important to know that the water softener’s overflow sensor is what shuts off the water when the tank becomes full. If the overflow sensor fails, then water will continue to pour into the tank until it overflows.

The following are reasons why a water softener might be spilling over:

  • Overfilled tanks mean that more salt has been added than necessary, meaning that it takes more time for all of it to dissolve for proper filtration.
  • Unbalanced salt levels – in which case, more salt than is needed for proper filtration is added to the tank, and therefore there will be no filtration.
  • Going through an alarm cycle means the tank is getting full, and the overflow sensor suddenly turns on the water. The tank will overflow.
  • Occasionally, you might find that your water softener is overflowing even after making sure that it isn’t overfilled.
  • This may be due to a problem with the unit’s pressure release valve. If this is the case, immediately call a plumber.
  • Water that continuously overflows from your softener’s tank might mean that you’ve got a problem with its pressure valve or the valves in your plumbing system. 

It is important to note that if the overflow is due to too much water being added to the water softener, it can sometimes get fixed by simply draining some of the tanks and adding more salt.

Is It Normal To Have Water In The Salt Tank Of A Water Softener?

Yes! It’s perfectly normal to have water in the salt tank of your water softener. Water in your salt tank is a widespread occurrence and not something to be alarmed about.

Water can sometimes appear in the salt tank because of how it’s been added to the water softener.

When you add new salt to your system, it may contain some moisture from evaporating while being processed into granules at the factory. The water-salt mixture is then added to the salt tank in a tray.

Since the water evaporates, the tray can absorb some moisture from the air while sitting on your utility room floor or in other locations exposed to air.

The salt in that remaining moisture-free tray then gets added to your system and will end up in the salt tank, even though none of that initial moisture was present.

The water in the salt tank is temporary water that will evaporate and be used up once the system starts working. It’s not a problem, but it can look odd when it happens for the first time if you aren’t expecting it.

The important thing to know is that it happens, and it won’t last. Water in your system is not a sign of anything being wrong.

Is The Water In The Water Softener Normal?

Yes! Water in a water softener is normal. Most of the time, the water coming out of your home’s water softener looks and smells just like the regular water from your faucet. There isn’t a way to tell if it has been softened or not.

It should work fine as long as the water coming out of your electrolytic water softener looks and smells the same as regular tap water.

However, even though there is no way to tell if your water has been softened or not, there are a few things that you can do to help ensure that it is being properly softened.

First, check your concentration levels:

For each full tank of hard water (i.e., water that has already gone through your water softener), most water softeners will require to be recharged with several pounds of salt.

This may be anywhere from 1-5 Lbs depending on the tank size. So, if you are not sure how much salt your system needs, you can estimate it by keeping track of the salt amount and concentration levels.

Secondly, you can watch the resin bed (if your unit contains a resin bed). This bed can become over-saturated, which will prevent softness in your water.

You may need to connect a “dosing” device  to the resin bed and regularly check the levels if this happens.

As long as your water is being softened properly, you won’t need to worry about how much salt you’re putting into your system. Just be sure to keep it well-lit and sanitized at all times.

Air In My Water Lines?

Your water lines boast air because the pipes are porous. As water passes through the pipe, it makes tiny spaces for air to expand in. These spaces help create a fluid flow that keeps the pipe from collapsing.

As a result, there is very little pressure on your water lines, and thus no force is required for them to release water.

However, suppose you have an older home or are connected to the city’s old infrastructure.

In that case, this concept does not apply, and you will experience pressure from time to time when your pipes release air into your home or when running cold water takes longer than expected.

This pressure that you experience is referred to as a relief valve. A relief valve is needed because if too much pressure builds up behind the water, it could cause a pipe to burst.

This is common in homes with older infrastructure and those built on high ground or near lakes and rivers, where water levels rise regularly.

Pressure should be checked in the fall after the summer months when water levels begin to rise again.

You may also experience pressure in your pipes when you’re taking a shower or letting the water run from the kitchen faucet.

It is a result of the water constantly being released from your pipes. You can manually add the release to your home’s plumbing.

It can be automatically controlled by a pressure-reducing valve that regulates the amount of air allowed into your water lines.

When this valve senses too much air inside the pipes, it reduces its release until the water flowing through it adjusts to the right level.

Can Water Softener Cause Plumbing Issues?

Yes! A water softener can cause plumbing issues such as:

-Stained fabric in the laundry

-Discolored dishes and silverware

-Soap scum in a bathtub, shower, sink, toilet, and washing machine

-Mildew on surfaces near a water softener (e.g., window sills)

Plumbing issues can be caused by mineral salts used to soften water. Today’s homes often have 18 – 20 parts per million salt from water softeners.

Because minerals dissolved in the water prevent water from seeping into the surrounding soil and evaporating, they ultimately build up in plumbing pipes and household surfaces.

These mineral deposits become a sludge-like substance and can corrode pipes and fixtures, affecting their appearance, cleaning ability, and performance.

As water passes through a pipe, it is pushed out of the pipe by a constant freshwater flow.

This back pressure results in soap scum accumulating at bends or valves in the piping system where flow is restricted.

The mineral content of softened water can also cause soap scum to stick to the insides of pipes and valves, further restricting flow.

This is not a problem with ordinary hard water, which flows freely through pipes with only occasional scale deposits.

Do Water Softeners Clog Pipes?

Yes! water softeners do clog pipes. If your water softener does not have an automatic shut-off, it can cause you to have a water line break and create an expensive repair. It can also lead to a leak that causes more damage.

In addition, the filtering process removes some of the essential minerals in your water, which can result in poor quality if you forget to change your filter.

Thankfully, there are plenty of filters available that will help prevent this from happening while keeping your iron levels normal at all times.

If you have a water softener and you’re experiencing problems with your plumbing, you must call in a licensed plumber right away to prevent further damage.

A professional will be able to determine where the issue is coming from and take the necessary steps to help fix it.

How Do You Fix Air In Water Pipes?

Fixing air in water pipes is easy if you use a flexible tube. You may choose to use plastic wrap or aluminum foil, but the best option is the flexible tube.

Flexible tubing comes in various lengths with diameters ranging from 1/8” – to ¾,” You can purchase it at your local hardware store. With its soft and pliable material, it will not harm your pipes.

What You Need:

Flexible Tube Or Hose

Take the flexible tube, and wrap it around the water pipe. Slide it up and down to allow optimal coverage when a seal is needed.

Before tightening the hose, make sure that there are no leaks. If you find a leak, look for an opening where the air is getting into the water pipe, as this is not an effective fix.

Once you leak the free area, use your hand to tighten the hose until it forms a strong seal with the pipe.

The hose or tube should be able to seal the water pipe it is wrapped around. A thin layer of warm water will allow for a tighter seal.

Use this method to prevent expensive water damage and mildew found in poorly sealed plumbing lines.

This simple method can save you money, time, and unnecessary stress. By utilizing pliable tubing and wrapping it around your water pipes, you can eliminate air.

This can prevent clogs, but it can also prevent damaging the pipes in the future. Best of all, you don’t need to spend a lot of money on this method.

Can Water Softeners Flood?

Yes! A water softener can flood in situations where it is stuck in a regeneration or backwash cycle.

In regeneration, salt is removed from the water tank and thrown into the brine tank. If there is too much water in the softener at this time, it can cause a flood upstairs or in your garage.

Calcium and magnesium precipitate out of hard water to form scale on pipes and heater fins in the backwash cycle.

The backwash cycle is designed to remove this scale by reversing the water flow through these pipes with high-pressure jets of freshwater.

If the softener is overcharged, the water pressure from the backwash cycle can blow out a pipe or cause a flood upstairs or in your garage.

The first step in avoiding a flood from a water softener is to operate the unit with the correct amount of salt.

The amount of salt required for soft water depends on the hardness of your water and how much water you will be using.

Soft water requires less salt than hard water. Hard water requires sodium to calcium ratio of 18:1 in the softener, while soft water requires a ratio of 16:1.

If you want to use 3 gallons of hard well water in your softener, but your softener is rated for 2 gallons, add 1/6th teaspoon of salt for every gallon of well water.

Using this method will use the correct amount of salt without measuring it.

In addition to using the correct salt amount. Inspect brine tanks for rust and overflow tubes for corrosion.

If your softener is more than 6 years old, replacing the anode rod in the brine tank is good.

The anode rod prevents corrosion of the tank by making a small amount of electricity flow into the tank via electrolysis.

If your anode rod is corroded, it will not be able to do its job correctly. You should also inspect the softener for leaks every time you refill it.

Does A Water Softener Need An Overflow?

Yes! Overflows are your last line of defense, so they’re important! Overflows are reservoirs that protect your water softener from operating at too low a pressure.

When there’s not enough pressure to flow the softened water through your plumbing and house, this overflow will catch the excess to prevent damage or leaking.

Can your water softener operate without an overflow? It can, but only temporarily, as long as you don’t decrease the flow rate.

If you have a light fixture that produces a minute amount of hot water, or if a pipe springs a leak and reduces the flow.

Your softener will run out of softened water to use before the tank fills up; without an overflow, it will start dumping salt into your drain.

As the salt dissolves, it’ll build up enough pressure to shoot out the overflow, then deliver the saltwater back into your softened water tank.

This is why I suggested that you install a bypass valve before you install your softener.

The overflow pipe is usually attached to the top of your water softener, somewhere near where your input hose hooks up.

It’s also connected to a pressure relief valve (PRV) which lets excess pressure drain into the tank or escape through another outlet.

There are many different types of water softeners, so don’t be surprised if you come across more than one design.

For example, some water softeners feature an automatic bypass valve (ABV), allowing excess hardness and pressure to escape that might otherwise cause damage or leaking.

Most water softeners can work just fine without an overflow, but if yours requires one, I’d suggest installing it before your installation is complete.

How Do I Know If My Water Softener Is Too High?

Knowing if your water softener is too high can be tricky—all in all, you can still do it.

First, there are two ways to determine if it is too high; the first is by using a sodium chloride meter, and the second is by using a water hardness test kit.

If you are using a sodium chloride meter, this will tell you whether or not your salt levels are too high. The salt levels should be 20 percent (2 tablespoons).

If you’re using the water hardness test kit, this will tell you how much calcium there is in your water and also how much magnesium.

The test kit can tell you if your water hardness is too high. The calcium levels should not exceed 300 ppm, while magnesium should be no higher than 350 ppm.

If your water softener turns out to be too much salt, you need to adjust it.

The first thing you need to do is look at the salt meter and make sure that there are no salt crystals in the tank.

If there are, the water softener needs to be cleaned before trying again. If they are not, then try adjusting it manually. Plugin your unit and wait until it starts up.

Then open up the drain valves located on either side of the unit. If you have a lower-end model, it will be located near the white float.

Once they are all open, let them sit for 3 hours to let the water drain out. After that, close and let it sit in place overnight.

You should see how much salt is being discharged. If there are no crystals, you need to adjust the unit manually.

First, turn on the unit and set it to its highest setting so that it discharges for 5 minutes.

If there are salt crystals still in the system, you’ll have to call a professional. However, if it’s not, you need to adjust the unit manually.


Water softener installation is a big job. It can be difficult and confusing, especially if you do it yourself.

If you are going to try water softener installation on your own, I suggest getting help from a professional.

They will be able to guide you through the process so that when you’re done, you won’t have any misfortunes.


Hi! I I faced many questions from customers about different products, and there was hardly any help on the internet. After learning all the things about these products as a manager the hard way, I decided to start a blog and help other people.
