Hot Water in Toilet | Every Homeowner should know

Is it an okay or bad idea when it comes to hot water in the toilet? Some people believe that the added convenience of having hot water at your fingertips when you’re taking care of business is worth the extra expense, while others find the whole concept unsettling. 

Let’s take a nearer glance at both sides of this heated debate. On the one hand, having hot water available can make cleaning yourself up after using the restroom more pleasant- no more icy cold shock in the middle of winter! 

However, some people worry about hygiene issues- will having hot water cause bacteria to grow more quickly?

Is it OK to put hot water in the toilet?

While some avoid hot water pouring into the toilet and others do. Why?

Pros of hot water in the toilet

· Hot water can unclog the toilet and clear the trapway.

· Hot water with soap liquid can effectively unblock the toilet with oily or greasy materials.

· Hot water can kill bacteria and fungus that grow bottom of the toilet.

· In winter seasons, hot water can clear the passage very well when drainage is frozen.

Cons of hot water

·   The extremely hot water can melt the wax seal around the toilet bowl, leading to leaks and water damage. 

· It can also cause the rubber gasket to deteriorate prematurely. 

· Additionally, if there is a clog in the system, pouring hot water down the drain will only worsen. Instead of using hot water, try using other ways to clear the clog.

Why is your toilet water hot?

Your toilet water is hot because of your tankless water heater. When you switch on the power to activate the heat, it will take a few minutes for the temperature to stabilize. It might continue warming up nicely with use. (The hotter your tankless water heater gets, the more its fuel consumption goes down). 

However, if someone flushes while they’re still waiting for their hot water, they have to wait until it starts heating up again before they get any hot water. 

It’s just like an oven: if you start heating it up when there’s nothing in there but cold air, then it will take longer than starting when there’s some heat already in place coming off whatever was inside beforehand or left on throughout the day.

You don’t want your tankless water heater to turn on when you flush because it will waste fuel and energy, but if you can time this in-between flushes, then it won’t cause any problems. 

There are two solutions:

· Either wait until the next person is ready before flushing yourself, or 

· Request that the last person flushes before anyone else goes if they’ve already got their hot water out of the way.

Reasons for waiting:

– Your tankless water heater will not operate if there isn’t a demand for it. If you go in knowing that the next person doesn’t need hot water, then your energy cost goes down as well as your environmental footprint! Remember, trying to heat something before it’s been called for is a waste of fuel and money.

– Your tankless water heater needs to maintain its temperature so that once hot water has been used up, it can quickly heat more without waiting too long between uses (this is why if you use all of your hot water very quickly, it will sometimes “queue” itself up). 

Also, having someone wash their hands when it hasn’t had time to reheat after flushing means wasting two cycles instead of one.

– Perhaps the toilet is only being used for cold or lukewarm water, so there’s no risk in waiting between flushes!

why there be hot water in toilet

Why would there be hot water in the toilet?

You wouldn’t expect to find hot water in a toilet. You might be able to understand the addition of cold water, but what would be the purpose of piping hot water into a toilet?

Hot Water Toilets (or HWTs) are an interesting piece of bathroom equipment that does just that: add hot water to the tanks of flushing toilets (those things you use every day). 

Rather than using city pipes, which can fluctuate throughout the day and provide cool or even cold water for flushing your waste away, HWTs rely on an independent system. 

By heating up their own water supply, they can ensure that each flush is accompanied by a warm liquid instead of a lukewarm or chilly liquid.

This is a great system for those in areas where water is often at a premium or who have to deal with fluctuating city water pressure. 

By adding their own reserve, these HWTs can ensure that they always have hot water when needed. From mining towns in the mountains of Colombia to modern buildings in Singapore, Hot Water Toilets are an excellent option for any bathroom setup.

Will hot water help unclog a toilet?

Yes, hot water can sometimes help to clear a small clog in the toilet. If you pour a pot of hot water into the toilet bowl, it can help loosen the clog and make it more manageable to flush away. 

However, if the clog is more serious, this will not be enough to clear it. At that point, you will need to use a plunger or a plumbing snake to clear the clog.

Note: It is not essential, nor is it helpful, to flush any combination of Drano, toilet cleaners, kitty litter, vinegar, laundry detergent, and/or bleach down the drain. 

These products do NOT work any better than plunging or using a plumbing snake. In fact, in some cases, they can cause more damage if they remain in an agitated state when discharged into your disposal line.

How do you flush a toilet with hot water?

Using the faucet on your sink, fill a bucket with about one gallon of water at room temperature. Pour this water into your toilet tank. 

You can get rid of the first three to four flushes by pouring another bucket of hot water from your sink down the same toilet bowl right after pouring in the cold water. After that, everything should be fine for you and your family.

Hot water in the toilet cistern

Hot water in the toilet cistern is a waste of energy, and it can cause your water bills to increase. By repairing the leaky tap, you can save money and energy.

The following tips will help you repair the tap and stop the wastewater:

1. The first step is to remove the cover of your toilet’s cistern. Use a screwdriver and undo the screws that hold it in place, and pull it up to take it out. 

2. Flush your cistern until there is nothing left in it. Then, remove any sediment or dirt from inside [the cistern] by wiping with a cloth or low-pressure hose pipe (if you can). 

3. If your basin isn’t letting out enough cold water when you turn on the hot tap, then you’ll need to replace the rubber washer which sits beneath the tap head inside [the bath/sink]. You might need an adjustable spanner or basin spanner for this. 

Once removing the old washer, take the new one and push it down onto the tap spindle. Then tighten up the screw to secure it in place.

4. If your hot water tap is constantly running even though it hasn’t been used, then you’ll need to check your cistern’s flapper valve. 

Before you do anything, shut off the water main to your house and flush the toilet tank twice by pulling on the flush chain so that all of the water has gone down into the toilet bowl. 

Once this is done, open up the cistern again and remove any sediment or dirt from inside using a cloth or low-pressure hose pipe (if you can). 

What happens if you pour boiling hot water into the toilet?

Improper mixing of the hot and cold water supply can result in hot water entering the bowl before it can cool down. If you do that, what goes into the bowl is very hot (up to 130 degrees F or more).

The opposite is more likely to happen due to an overly forceful flush or dumping cold water into a hot bowl. Plastic pipes would be more prone to damage from the thermal shock than metal ones. 

But this is much less likely if you wait for a minute after pouring in hot water to let it cool down or if you flush quickly after pouring in the cold water.

Q1. What makes a toilet gurgle?

As everyone knows, toilets can make all kinds of weird sounds. The main reason to make a toilet gurgle is vent pipe is blocked. 

Another common cause is when wastewater backs up into the toilet bowl from the drainpipe. This can happen when there’s too much waste for the pipe to handle or something blocking the pipe.

Q2. Why does my toilet spits water when I flush?

Because it’s clogged, and sometimes water causes the blockage to dislodge.
Maintaining a regular schedule for flushing is important because sediments can build up in the trap and partially plug your toilet’s outlet pipe, causing it to spit water when flushed. 

Sediments from hard water can also build upon the seal of rubber gaskets, which reduces their effectiveness in creating an air-tight seal by allowing menacing tree gases to escape, thereby adding the risk of chlorine or other harmful residues backflow into your home through your toilet bowl downstream. 

Q3. Hot or cold water to the toilet – which is better?

Hot water is the best way to clean a toilet. The hotter, the better, in fact. When the water is hot, it loosens up any dirt or grime that may be built up and makes it easier to clean away. Plus, it just feels nicer to have a hot shower after cleaning the toilet!
