Can I Put CLR In The Water Heater?

A water heater is used to heat water for heating buildings or domestic hot water. It plays a vital role in modern life, and you can find it in most households.

It heats water for one or more buildings, with the heated water then distributed through copper pipes called service lines to individual taps.

Water heaters work by heating the input hot water and then sending its thermal energy as infrared radiation through the building’s walls and into rooms heated by a convection current.

This current comes through when this hot air rises from near-floor to higher-level floors near ceiling level.

The overall thermal mass of the water heater serves to store heat in the water during this process until its need arises.

Yes. It’s safe to use bleach in a water heater and may help eliminate odors by acting as a bactericide. However, do not put bleach in your water heater if the model doesn’t call for it because it may damage the unit.

Follow manufacturer directions for adding bleach and avoid putting any other chemical or cleaner into your water heater.

As they can dangerously react with each other and create toxic fumes that you could release in your home.

As with any chemical, the amount you use can affect the outcome.

Too much bleach will not perform as well as it should, and too little bleach may not break down the odor-causing bacteria.

The EPA considers 1 ounce of bleach appropriate for a 100-gallon water heater, but if you want to be extra cautious about this, use 1/4 cup for every gallon of hot water.

It’s unnecessary to check the bleach container to determine how much bleach to add.

Some manufacturers, such as GE and Maytag, have their models labeled with a “unit of measure” reminder that tells you how much bleach to use.

Other manufacturers use a general amount of 1/4 cup per gallon, so if your manufacturer does not specify a unit of measure.

You can use the same amount per gallon as for other household cleaners.

Ensure you follow all instructions for your particular model. If you still doubt whether it’s safe to use bleach in your water heater.

Consider that military and hospitals used bleach for many years, so it’s not regarded as harmful.

What Should You Not Put In A Water Heater?

Below are the dos and don’ts of putting and not putting in a water heater.

First off, never use this as garbage disposal. Adding anything with fat or grease will cause clogging issues, so stay clear of that.

Please don’t put any heavily scented items or cleaners in the water heater either, as they can irritate the residents’ noses and trigger air freshener refills too often.

Also, you may have to drain your water heater sooner because of this.

Don’t use soap products. Soap removes oils and fats, so adding it to the grease already there will only worsen matters.

Your water heater will become clogged and cause heating issues. You can use regular detergent but not dish soap or laundry detergent.

Lastly, don’t keep any candy, dog treats, and other food items in your water heater. Food products contain residue that can attract bugs. This is especially important for children.

What Kind Of Vinegar Do You Use In A Water Heater?

There are many types of vinegar available, so you have more choices in deciding what kind of vinegar to use for your water heater.

Just like how there are so many types of vinegar, there are various options for what style you want to use.

This can range from the best kind of vinegar for your water heater determined by your specific water heater.

It would be best to consider using white vinegar or red wine vinegar, or a combination of them.

As with any other choice in life, you must consult with someone knowledgeable about this subject before deciding what kind and the purchase price.

There are other considerations to make when choosing the best type of vinegar. The best kind is vinegar with lots of organic material in it.

This prevents scale formation in your water heater, so it is essential to buy organic vinegar that contains an abundance of this substance.

There are also other bacterial inhibitors, such as trisodium phosphate, that you can use, so be sure to find out if your brand contains these when shopping for non-diluted products.

Some Common Vinegar You Can Use Include:

Balsamic vinegar – This uses the traditional method of adding a lot of raw wine to the vinegar. This makes it very strong, so use it sparingly when heating.

White distilled: The distilled water used in this process is great because it removes impurities but doesn’t remove many nutrients.

It’s still important to use if you want to remove free chlorine byproducts, which are harmful and can cause corrosion on your water heater.

Red wine: If you decide to buy some red wine to use in your water heater, avoid the cheap stuff.

Although it’s cheaper, it doesn’t contain a ton of organic material that will prevent scale formation.

White distilled: This is another excellent option for maintaining your water heater at its best.

It works just as well as red wine vinegar if you know how much to use and drink it immediately or freeze it.

Other Things To Consider

You need to consider other considerations when choosing the best kind of vinegar for your water heater. The most important one is the amount of vinegar you use.

You need to make sure that you don’t use too much, especially if it’s a white distilled vinegar and has chemicals. This can cause scale formation and damage your water heater.

Think about how much you will use each time before deciding on how many types of vinegar to buy.

White distilled vinegar is more expensive than red wine vinegar, so it may be good to use a combination.

It’s important to remember that every time you heat water with vinegar in it, you’re increasing the amount of money you will pay for heat that year.

What Does Draining Your Water Heater Do?

Draining your water heater does a lot of things.

1. It heats the water in the tank and allows it to get hot enough for your showers (cold showers are no fun.)

2. It keeps cold water from mixing with hot water, so you don’t have a mix of cold & hot.

3. It prevents corrosion in the pipes and “sumps” behind most water heaters. (What’s a “sump,” you ask? That’s where all the dirty old “old water” goes…just kidding)

4. It drains out any little bits of rust or calcium buildup in the tank.

5. It keeps the tank clean of minerals, sediment, and hair that may have accumulated over time in your water heater.

Keep your water heater clean to prevent mold and mildew buildup inside the tank.

6. It reduces odors inside your water heater. Cleaning the tank removes any foul odors trapped inside and prevents new odors from building up in future cycles.

7. It keeps your water heater from leaking. Water heaters not drained for an extended period are more likely to leak than those you have adequately cleaned and drained.

Please keep it clean and leak-free.

Can You Box In A Water Heater?

Yes. You can box in a water heater, provided the water heater is properly vented. An ideal location for a water heater is outside of the living space.

If you have a basement, placing it there means it will be easier to run electrical wires and other necessary materials for installation.

Box in your water heater by removing any walls directly next to it, putting drywall up on every exterior side and ceiling.

Then doing some drywall work where the vent pipe attaches to the wall or ceiling outside the box so mold can’t grow inside your enclosure.

Also, ensure that you don’t cover up your pressure relief valve. The purpose of this is to automatically open and relieve excess pressure within the tank when the water heats.

Covering it up or blocking it with drywall will cause the tank’s temperature to increase significantly and may cause an explosion from overheating if there is no means of venting gases out of the tank.

Also, be sure to leave sufficient room around the vent pipe so that hot and cold water can move from one side of the tank to the other while they are flowing because of the expansion of water within the tank.

A good rule of thumb is 1 inch (25mm) per foot of height or a maximum of three inches (75mm) between any parts inside the box.

Please do not put any electrical wiring through a box as it could short out and potentially lead to an explosion or fire because of overheating.

What Is The White Stuff At The Bottom Of My Water Heater?

The white stuff in the bottom of your heater is a mineral buildup typically composed of calcium, magnesium, and deposits from the water itself.

Water heaters experience a buildup of minerals in two ways;

Through water that is too hard for the heater to process or through acidic water that has dissolved minerals and then neutralized with alkaline chemicals.

This mineral buildup can eventually impede your heater’s functioning by clogging the valve or gas burner if not adequately taken care of.

The most common symptoms include hot water performance or unusual noise from your appliance.

A thorough cleaning once every two years is the best recommendation to remove the deposits and avoid any issues.

When performed by a professional, this deep clean will extend the lifespan of your water heater and help it continue to operate efficiently.

The process involves draining, decoking, and thoroughly flushing all mineral deposits in your tank using a cleanup solution called Hydro Flush.

Draining of the hydro flush solution is then done with a special hose, leaving your appliance free of any deposits.

Can I Build A Closet Around My Water Heater?

Yes. You can build a closet around your water heater to prevent water from leaking onto your flooring.

The first step to creating a watertight closet is deciding its location and marking the area.

You need to identify any pipes running under the wall you plan on building the closet around, as well as any transformer or power-board that might be in that wall.

Next, mark out your plans on the wall with a pencil and make sure they are clear of any obstructions, such as pipes or electrical boxes.

The next step is to take the measurements of your water heater and mark them out on your wall.

Ensure that you leave sufficient room for the closet door to open without hitting anything and that you measure the height of the water heater if you want to install a shelf above it.

Once you have made the appropriate markings, mark out where you plan on putting your studs and where you will nail them.

Make sure you leave yourself some space around the water heater to fit a closet door.

The next step is to nail in your studs, ensuring they are level and upright. Always make sure that your nails go into the stud at least 3/4 inches.

If you’re using standard-sized 2x4s for your studs, you should be at 3/4 of an inch to the end of the board.

If you are using pocket screws, you should have about 1/4 of an inch on both sides at the end of the board.

Now that when your studs nail up, it’s time to insulate them. The easiest way you can do this is to buy a piece of paper then cover the inside of your closet with it.

Then cut small pieces off and staple them all over the paper. Make sure that you leave 3/4 of an inch of space between each stud so that you have enough room for your drywall.

You can now nail up the drywall. If you do not have a lot to cover, it’s best to use one piece of 11-ounce drywall.

But if you are covering a larger area than recommended for an 11-ounce piece of drywall, it is better to use two 6-ounce pieces instead.

It would be best if you always nailed up the studs first, as well as the sub-floor. If you don’t, you will end up with a bunch of holes and rough spots in your wall.

Once that’s done, it is time to run your electrical wires and plumbing lines to your pipes and outlets.

You do not have to solder them into place if you install a new water heater, but you should always paint the wire’s ends with a primer before running them through the wall using wire nails.

The next step is to ensure the wall seals. You can do this by using a caulk gun and applying a large bead of caulk around the edges of your wall and on the outer-facing parts of your studs.

If you are using a door for your closet, use spray foam to seal any gaps left in the wall from nails or screws.

Once that’s done, it is time to install your closet door. You should be able to get a fairly large door for a closet in about 6 feet of space.

Make sure you leave enough room on either side of the door for the waste pipes that you can connect to your water heater.

The last step is to paint everything and install it before anyone else breaks into your house while you are gone.

Will Vinegar Dissolve Water Heater Sediment?

Yes. Vinegar will dissolve water heater sediment.

You can use vinegar as a natural, inexpensive, and environmentally friendly water heater sediment remover.

You can mix white vinegar with a bit of dish soap and rub it over the sediment on your water heater or faucet before turning off the power.

The mixture will remove the mineral deposits, making them soft and easy to flush down your disposal or out through your drains.

If you have a vertical water heater, you can place a cup full of vinegar at the bottom of the tank. Pour 2 cups of vinegar into the top of your water heater before switching it on.

You’ll want to turn your water heater off for about 6 hours for it to do its job.

When you switch it back on again, any minerals or sediment dissolved in the water will flush out through your drains. As a bonus, your water will smell fresh.

Professional cleaners contain vinegar that can dissolve mineral deposits on your water heater and faucets. Luckily, you don’t have to do any scrubbing or vacuuming.

Just spray the cleaner on and wait. The mineral deposits will dissolve even faster.


Water heater sediment is one of the most common problems with your water heater. Luckily, it’s a relatively easy problem to solve.

If you keep your water heater regularly maintained and always follow the manufacturer’s instructions, you should never deal with sediment buildup again.

Be sure to always think about what you can do to maintain your appliance so that it can last for many years to come.
