How to Stop a Toilet from Sweating?

What causes your toilet to sweat in the first place, and how to stop a toilet from sweating?

Have you ever noticed how much sweat your toilet produces? You’ll notice that a lot of water has clung to the tank. This toilet sweat will then fall down onto the floor and maybe onto the adjacent walls. The temperature differential causes the air to leak water, resulting in one steamy, drippy toilet. A sweaty toilet is just an annoyance. If you do not handle this issue, the excess water from the toilet leaks onto the floor and may quickly destroy the bathroom floor and walls. It is something you should solve sooner or later.

Condensation also raises the humidity level in your bathroom. This is an area that becomes extremely humid very quickly. Excess moisture increases the chance of fungal development, which may be harmful to your health and spread throughout your house. Mildew may also stain baseboard molding, make drywall wet, and discolor wall paint. Fungal growth is very tough to eradicate and may severely reduce the value of your house. In the worst-case situation, you may have to remodel the whole house to remove the fungus growth.

we’ll examine in depth the phenomenon known as “toilet from sweating.” In the conclusion of this, you should understand why your toilet sweats and how to easily remedy the issue. A sweaty toilet may be reduced or eliminated by changing the atmosphere in your bathroom to prevent this activity. It might also help to keep your bathroom floor in good shape. So, what are your options? The majority of the remedies are not doable by yourself, but rather require the services of a plumber.

Why Does My Toilet Tank Have Condensation?

Toilet from Sweating

Aaahhh, the sweating toilet. This seems to be an unusual occurrence; yet, if you’re knowledgeable with science, you’ll recognize that it’s no different from seeing condensation on your windows after a chilly night. It’s also the explanation for the dew on your lawn.

The perspiration you see on the toilet is really moisture drawn from the air in your bathroom. As you are aware, the air in your bathroom is quite humid. This is due to the fact that you take your showers and baths here. In fact, the bathroom is most likely the most humid room in your house. This is a damp, drippy, and all-too-common problem for homeowners, and it is one that can escalate and do major damage to bathroom floors if left unchecked.

Although the toilets sweat only on warm, humid days, they can drop a surprisingly large amount of water in a very short time. Several manufacturers make toilet-tank insulators that claim to cure sweaty toilets, but most don’t work very well.

So, why exactly is your toilet sweating, and what can you do to stop this nuisance before it leads to mold, mildew, and water damage?

The good news is that the sweaty moisture on the outside of your toilet isn’t caused by a leak or plumbing backup – so don’t get too grossed out! Instead, that sweat is simply condensation, usually caused by a discrepancy in temperature.

When the weather turns hot and humid, there’s a lot of moisture in the air. At the same time, the water entering the toilet tank is comparatively cold—about 50° to 60°F. When the warm, moist air hits the cool porcelain toilet surfaces, the air condenses, turns to water, and soon drips onto the floor.

When too much condensation builds up, little drips and drops can begin to move down your toilet and splash to the floor below. So even though a drip here and there may not be enough to make you worry, a “drip here and there” over a long period of time can really add up when left untreated.

Both mold and rotting can occur as a result of prolonged wetness, forcing you to have to replace either the flooring base around the toilet or even the entire bathroom floor.

It’s more than a mild inconvenience when condensation starts to form on the outside of your toilet tank; it can cause serious damage by dripping onto your bathroom floor. It can leave the floor damp for days, damaging the floor tiles and, in older toilets, even the bolts that hold the toilet to the floor. Fortunately, there are some quick and affordable ways to stop the toilet from sweating.

Best ways to stop toilet tank sweating

Remove the water from your bathroom. To begin, you may take efforts to ensure that the air in your bathroom does not contain a lot of water.

  1. Install an exhaust fan and utilize it when showering. This will help to reduce the general humidity and warmth of the bathroom, reducing the likelihood of your toilet cistern sweating.
  2. Take shorter, colder showers to prevent water from evaporating into the air. It’s very uncommon for the bathroom to get too humid if you like lengthy, steamy showers and baths. One of the most basic strategies is to reduce the number of hot showers and baths you take each week. Taking cold showers has health advantages!
  3. After taking a shower, dry the shower walls.
  4. When you complete your shower, open the bathroom door. This improves overall ventilation and allows heated air to exit more quickly. That being stated, you should only open the windows if the outside air is not more humid than the air inside your house. If it’s humid outside, you’re merely inviting extra moisture into your house.
  5. After a shower, use a portable dehumidifier to dry out the bathroom. This is a smart investment not just for your toilets, but also for your house in general.
  6. To keep your whole home comfortable, consider installing a whole-house dehumidifier.
  7. An air conditioner works well as a dehumidifier. Use your air conditioner if you have it.
  8. Cover the tank: Wrap a towel or other absorbent material around the exterior of the tank to catch any dropping moisture.
  9. Insulate the tank. These are available in-store and are constructed of protective materials such as foam, clinging to the interior of your tank and preventing it from becoming too cold.
  10. Reduce the temperature of your shower or bath: this reduces the quantity of heat and humidity in the room.
  11. Purchase a water-saving toilet: If you have less water in your tank, condensation will be less likely to develop.
  12. Purchase a toilet that has a temperature-increasing (tempering) tank: A second tank will pre-warm the water before it enters the bigger tank.

Does your toilet tank sweat or moisture or condensation problem ? Here is the reason^ DISCLAIMER : this is a D.I.Y video only.

Clean the toilet frequently

Another reason toilets sweat is that they’re dirty. You can clean your tank with vinegar, baking soda, and hot water! Just dump these into the tank, let it sit for 20 minutes, then flush. Your toilet will sparkle in no time.

Insulate your toilet

It is also possible to prevent the toilet from sweating by insulating it. There are many options for insulating the toilet. You may either insulate the tank with insulation or cover the tank’s exterior with a cover to keep heat in. There are even insulated toilets on the market nowadays. However, unless you have a considerable budget, you may not want to replace your old toilets with these new ones.

Insulate the water line

One way to stop your toilet from sweating is to insulate the waterline. This means wrapping a layer of foam around the pipe, which will prevent condensation from forming on it. You can buy insulation kits for this purpose at most hardware stores, but if you’re on a budget, then just use an old towel or rag instead!

Warm up the toilet water

As previously stated, condensation happens when the toilet water is too cold. Warming the water in the toilet might also help to keep it from sweating. A mixing valve at the tank intake may be installed by a plumber. The mixing valve will inject warm water into the tank, ensuring that the tank water is not much colder than the air in your restroom. This solution should provide quick benefits.

This approach is only viable if you reside in a temperate climate. It is not feasible to overheat the toilet water. As a result, some householders may have to put up with a sweaty toilet throughout the summer, particularly when the weather is very hot and humid. To prevent condensation from sweaty toilets from affecting the flooring or adjoining walls, homeowners should make it a practice to clean their toilets with a cloth on a frequent basis.

A tank cover may be used to cover the complete exterior of the tank. Condensation will not occur if the colder tank does not come into contact with the warmer air. If you’re prepared to pay a little more, you may also replace your toilet tank with a new, insulated tank.

Warm up the tank’s water. When the tank is refilled, you may add an anti-sweat valve that mixes a little warm water in with the cold. No sweat as long as the water temperature approaches the ambient temperature in the room!

Reduce the tank’s water content.

The tank will sweat less if there is less water in it. Installing a low-flow toilet not only saves water but also minimizes the amount of condensation that a tank may produce. Your bathroom floor will remain drier if you combine a low-flow toilet with an insulated tank.

Check wax ring seal

The toilet may sweat if its wax ring seal is old or broken. This could mean that water is leaking from around the base of the toilet onto the floor underneath where you can’t see it. If you suspect this may happen to you, call a plumber to come over and look at it!

Dispose of the tank.

Some manufacturers provide tankless toilets for domestic use. They are not inexpensive, and they normally employ an electric pump to carry water into and out of the toilet. (Hint: a tankless electric toilet will not function during a power outage.) If you can’t get rid of the tank, think about installing a low-profile toilet. The colder the surrounding air is, the closer your toilet tank is to the floor. (Recall that heat rises.) Keeping your toilet tank hidden may help avoid large changes between the ambient temperature in the bathroom and the water temperature in the toilet tank.

Inspect the Flapper Valve

Last but not least, check the flapper valve, which is situated at the bottom of the tank, to determine whether it is leaking. Fresh, cold water is continually being pumped into the toilet if it is leaking. This will just increase the amount of condensation that collects on the toilet tank and other surfaces. When you stop the leak, the water in the tank will gradually warm up to room temperature. The quantity of condensation that occurs should be reduced as a result of this.

Repairing this leak can also save you money on your water costs. If fresh, cold water is continually entering the toilet bowl and tank, you’re consuming more water than required. Every year, a leak in the flapper valve may add hundreds of dollars to your water bill. Furthermore, the sound of freshwater constantly entering the toilet might be annoying to some individuals.

Put in an anti-sweat valve.

In the water supply pipe going to the toilet, install an anti-sweat valve. An anti-sweat valve provides a little amount of hot water to the toilet water line, raising the water temperature in the toilet enough to warm the tank and bowl. Even in the hottest heat, that’s all it takes to prevent condensation from developing.

How Do You Put an Anti-Sweat Valve in?

The installation of an anti-sweat valve is divided into three stages: preparation, valve installation, and temperature testing.

Prepare to install Anti-Sweat Valve

  1. Turn off the main water valve for the whole home.
  2. Drain the hot and cold water pipes by opening all sink and tub faucets and flushing all toilets. To prevent burning the internal components of the valve with a soldering torch, use brass compression adapters ($1.50 each) to make all connections to the valve.
  3. Insert a 5/8 x 5/8-in. compression adapter loosely into each of the three-valve ports. Place the valve against the horizontal cold-water pipe, with the bottom intake port parallel to the pipe.
  4. Make a note of where the valve’s center output port crosses the vertical pipe portion and mark it on the pipe. Mark the bottom intake port on the horizontal pipe as well.
  5. Finally, cut off the pipe portion using a hacksaw.
  6. Next, solder a 90-degree L-fitting to the vertical pipe coming down from the toilet and extend it with a 6-inch-long stub of 1/2-inch-dia. pipe.
  7. Use a MAPP gas torch and lead-free solder. Lead-free solder is quite tough, while MAPP gas burns hotter and works faster than propane.
  8. Now that the cold-water line is ready for the valve, find a neighboring hot-water line and cut a segment to take a new copper T-fitting.
  9. Insert the T-fitting into the line and connect it to a short vertical riser pipe with a 90-degree L-fitting and a short horizontal pipe stub.
  10. Direct the stub to the location under the toilet where the valve will be put.
  11. Solder the T- and L-connections together.
  12. Connect a length of pipe to the valve position.

Set up the Valve

  1. Apply a light application of pipe joint compound to the male threads of the three brass compression adapters (pipe dope).
  2. Insert the adapters into the valve ports and secure them with a wrench.
  3. Place a nut and compression ring on each pipe end before inserting the pipes into the adapters.
  4. Apply pipe dope to each compression ring and thread the nuts onto the adapters.
  5. Using a wrench, tighten each nut.
  6. Re-open the main water valve and inspect for leaks.

Perform a Temperature Check

  1. To modify the temperature of the water flowing through the valve, all you need is a slotted screwdriver.
  2. Begin by twisting the cold-water adjustment screw all the way counterclockwise.
  3. Next, crank the hot-water screw clockwise until it reaches the bottom. This will completely open the cold-water side and turn off the hot water.
  4. Next, flush the toilet and move the adjustment screw counterclockwise half a revolution to open the hot-water side.
  5. After about an hour, check the toilet for any condensation. Open up the hot-water side of the valve a bit more if required.
