How to Make Your Toilet Quieter?

Being in the toilet is a particular time to commune with the innermost part of the body as you get rid of body waste.

Having the world know about the goings-on in there can be frustrating and irritating. It can also cause you to be on the edge while doing the do.

No one wants a noisy toilet, either!

If your toilet seems to be noisy, there are a few tips you can apply so you and the rest of your family can respectably use the space.

Tighten Everything

An inexpensive way to ensuring there is some apparent quietude in the toilet is to always check for loose parts and then screw them back in place.

With constant use, clamps and pipes will get loose, so check all the visible areas, get a socket wrench and screwdriver and get to work tightening them.

If anything is loose in places, you can’t easily access, getting a plumber to check it out and correct it will help you get back that much-needed privacy.

Adjust Water Flow

The intensity of noise coming out from your toilet can be due to high water pressure from the water valve.

All you need to do is adjust the water valve to the desired water pressure level to reduce the noise.

You can also check the water flow if you notice some echo when you flush the toilet as there may be an obstacle in the valve preventing the flow-out of water.

Get the valve adjusted to a suitable level or change it entirely if it has a noticeable build-up in it.

Block the Sound

Alternatively, you can decide to block out the sound of flushing by using sound insulators, like foam tapes, to seal the wall gaps around the tank.

Steps to do that:

  • You need to remove the lid on the toilet tank
  • Make sure the edges are clean and dry so the tape will stay in place
  • Cut the adhesive foam tape and place around the edges of the lid and tank
  • Press lightly and close the lid

Doing this will suppress the attendant noise within the tank when you flush.


What to Look Out for Before Buying Quiet Flush Toilets?

Rough-In

Before setting out to buy your quiet flush toilet, knowing the rough-in is vital so you will know the right size for your bathroom.

You must be conversant with the distance to place the toilet flange from the back wall, space to leave in front of the bowl, and how to set the cold-water supply line.

You can use a measuring tape to get all the calculations right.

The rough-in could be 10”, 12” or 14”. Nonetheless, you should know the right one for the toilet bowl type you want to buy to save money and time.

Flushing System

In opting for a choice of quiet flush toilet, you have to consider the type of flushing system in it.

Some are noisy, such as the pressure-assisted system that uses pressurized air. On the other hand, a less noisy flushing system is the gravity flush that uses water to force the contents from the tanks and bowl into the trap-way while cleaning the bowl at the same time.

If you want to be eco-friendly, then a dual flush is a better option since you can choose between a partial or full flush – depending on the type of waste you have in mind.

In summary, the ideal flushing system should be sturdy, long-lasting, and efficient.

Flush Type

You should take cognizance of the type of flush you want in your choice of a toilet.

Do you want a single-flush where you have control over the quantity of water released or the dual-flush where you can select partial flush for liquid and a full flush for waste?

The flush type you choose will help you save or maximize the use of water, accordingly.

The more control you have over your flush type, the less noise you will produce as you use the product.

Bowl Shape and Height

The amount of space you have in your bathroom may be a determining factor in your toilet bowl shape.

You can decide to choose a smaller, round-front bowl that is suitable if your bathroom space is not ample enough. These variants look compact and will fit right in!

For better comfort and functional hygiene purposes, you could go for the elongated bowls, which is a popular choice in public restrooms.

When considering the bowl shape, you should also select a height that will make you comfortable when sitting or standing.

The options available include comfort height, natural height, right height, etc.. Whichever you choose, ensure that it is ADA-compliant.

Installation

After spending the right amount of money on getting the quiet toilet of your choice, you won’t want to encounter difficulties while setting it up.

Be on the lookout for toilets that have instruction manuals that are easy to understand.

It will make the job easier for you or even a professional saving you time and extra money.

Efficiency

To determine how efficient your eventual choice will be, you must check the number of gallons it ideally uses per flush (GPF).

A High-efficient toilet uses about 1.28 gallons per flush while some go as low as 0.8 GPF.
Your final choice should be Water Sense-certified by EPA. This gap between the sentences should not exist.

This is important if you live in areas that have water challenges considering that an efficient toilet is capable of getting rid of 600-1000 grams of waste in a single flush.


Frequently Asked Questions

Q. Why do you need a quiet flush toilet?

A. The more you can limit the number of people that are aware of your presence in the toilet, the better you will be able to expel body waste more effectively.

You don’t also want a toilet that will wake up the whole house in the middle of the night after flushing.

To maintain your dignity and avoid feeling embarrassed for performing a natural exercise, it is best to have a toilet that has features that do not make much noise.

Q. Which flushing system is ideal for a quiet flush toilet?

A. Well, gravity flush toilets are less noisy when compared to other flushing systems. This technology ensures that the force of water released from the toilet tank pushes the waste down the drain at an increased speed.

The intensity of the force of water also keeps the toilet bowl clean from remnants and stains.

The gravity system gives you a better flushing experience, conserves water, and is less expensive than other types.

Q. 1-piece or 2-piece toilet? Which is quieter?

A. The 1-piece toilet is less noisy since it flushes without water flowing down through pipes from a longer distance.

This is unlike the 2-piece toilet that depends on the gravity of water to flow into the toilet bowl from pressurized tanks or flush valves.

1-piece toilets with a simple design as a single unit have a lower profile than the two-piece systems.

Q. What is the GPF that will not make much noise?

A. If you want to enter and leave the toilet unnoticed, you need a toilet that uses about 1.6 GPF per flush.

They are less noisy compared to using a 1.28 GPF, which requires more pressure to provide a perfect flush, making it noisier.

While you want to save cost on water, it is essential to consider the volume of noise that gets generated when using a little quantity of water.

Q. What varieties of the quietest toilets are on the market?

A. Depending on your bathroom space and your personality, there are different varieties of toilets you can choose from.

Wall-hung Toilet: best to use in a situation where the bathroom space is small so that you can have more floor space. The toilet gets fixed on the wall, while the tank is inside the wall.

Corner Toilet: this is also ideal when managing space. It has a small tank, which reduces flushing quantity, making it quieter.

Tankless Toilet they do not require a dedicated tank but are, instead, directly connected to the water pipeline-thereby reducing the level of noise compared to a toilet that has a tank.

Standard Toilet They are the regular types of toilets we commonly see around. They consist of a tank and toilet bowl fixed to the ground. These variants are either round-shaped or elongated, and they are relatively more expensive.
