Why Is The Niagara Stealth Toilet Not Flushing Properly?

As the real feature of the Niagara toilet is its silent operation. It’s impressively silent to let you not go through any noise discomfort. So, the comfort level is the major league. 

The tank of this toilet is designed with noise-canceling technology. So, it will hardly release any noise into your toilet. On the other side, the tank is completely designed to remain full of water always. 

The tank never gets empty a little bit even after flushing water. As it uses pretty little water from the tank for a flush. Hence, the valve stays underwater which hardly creates noises that can be transmitted to outside of the tank from outside. 

Since Niagara Stealth toilet isn’t using a lot of water for flushing, so sometimes you can face Niagara stealth isn’t flushing properly. 

How To Fix Niagara Stealth Toilet If Not Flushing?

Niagara Stealth toilet keeps running

You can often face this issue or never at all. It all depends on your luck. But if you experience this issue, you need a solid way to fix it. 

Now, we are going to share methods that can help you to fix the Niagara stealth toilet not flushing properly.

  • Don’t Allow To Create Air Gap In The Tank

It can happen in your Niagara stealth toilet that the water level goes automatically down. And the water doesn’t fill up even the water supply is on.

 If you see your toilet’s tank is draining down water in between every 5 minutes, you should be concerned. As it creates an air gap which later on leads to disturbing water flush. 

Since there’s a Fluidmaster 400A valve that handles all the flushing tasks, it can sometimes be jammed. Though this is an extraordinary feature that prevents all the occasional leaks of the water. 

Else, it’s another reason that provides a powerful flush to clean the toilet easily. To prevent the water from draining if this valve gets leakage, you can replace the flush valve. 

If the problem stays persistent, you need to identify the real cause. Thus, to do so you need to stop the water supply. And observe how much time it’s taking for water dropping. You should measure at which level the water remains static. 

So, the level where the water isn’t dropping anymore is the cause that’s making water drain down and causing an air gap. 

If your Niagara stealth toilet is an old edition that runs with flapper operation, you can replace the flapper seal to solve water draining down at this stage. 

Now, Niagara has ditched the old school design and started designing toilets without flappers. As flapper hardly requires the change of the water because of the valve which is 360 degrees. 

Luckily, we all are saved with water as it uses a very little amount of water to flush.

  • Pour Hot Water

It often happens that water won’t be flushing from the Niagara stealth toilet if the air transfer tube is clogged. You can’t clean it manually because there is a risk to mismatch the position of the tube.

So, better remove the tank and pour a lot of hot water focusing the hole. It will solve the clogged transfer tube issue. The official troubleshooting video might help as well!

How To Ensure Niagara Stealth Toilet Keeps Running?

  • Don’t Throw Toilet Tissue

Do you just throw toilet tissues into the toilet always? Wait, What? Are you seriously doing this with your toilet? Whatever your toilet is Niagara stealth or any other toilet, you should never form this habit. 

Let’s be very frank! 

Why can’t you throw toilet tissues into Niagara stealth toilet? Well, the manufacturer has designed this toilet to be able to flush a maximum of 800 grams at one time. 

So, what’s causing the issue as the tissues are very lightweight? Well, while tissue gets absorbed into water its weight becomes the fourth time of the real weight. Else, while the flush occurs, the weight of water also gets doubled. 

Hence, make sure you are not throwing tissue papers into the Niagara stealth toilet at all. Otherwise not only flushing issue, but you can also get troubled with the Niagara stealth toilet jamming issue. 

It’s high time to ditch the habit of throwing toilet tissue now. And get a basket near to the toilet and use that for throwing tissues. It will save you from the extra hassle of the Niagara stealth toilet, not a flushing issue. 

  • Hot Water Therapy

What’s that? You are just wondering, right? 

However, water isn’t the savior of life. Water can solve any home or bathroom issues when it’s about cleaning and staying healthy. 

This is grandma’s old therapy that we are trying to talk about. Let’s get frank! You need to boil water of 5 liters and pour them into the toilet. 

What that will do, right? 

It will help the Niagara stealth toilet to be always clear from any kind of jamming. If nothing is coming into the way of flushing, flushing will never interrupt. 

You can try this water method once a week. So, the flushing interruption will never occur.

  • Clean toilet regularly: Use a toilet brush and toilet cleaner to scrub the bowl and jets to remove buildup and bacteria. This prevents clogged passages.
  • Inspect flapper annually: Replace the flapper if cracked or misshapen to maintain a watertight seal.
  • Use bowl cleaners monthly: Dropping a toilet bowl cleaner tablet into the tank once a month will help break down mineral deposits and waste buildup.
  • Avoid thick tissue and too much paper: Using excessive amounts of thick, plush toilet paper can lead to clogging. Stick to only a few sheets of thinner 2-ply tissue at a time.
  • Don’t flush wipes or other objects: Baby wipes, feminine hygiene products, and other items not designed for toilets can easily get stuck and cause obstructions. Only flush toilet paper.

Following these simple toilet care tips will help minimize flushing problems and keep your Niagara Stealth toilet working properly for years to come.

Frequently Asked Questions About Niagara Stealth Toilets That Won’t Flush

Why is my toilet not flushing when I flush?

The most common reasons a Niagara Stealth toilet won’t flush when you try to flush it include:
1. Clogged drainage passages or drain pipe obstructing waste flow

How do you fix a running toilet that won’t flush?

For a Niagara Stealth toilet that runs continuously but doesn’t flush right, the problem is most likely a flapper that isn’t sealing closed. This causes water to leak from the tank down into the bowl while also reducing tank volume needed to flush. Fix this issue by:
1. Turning off the water supply

3. Replacing the flapper if it is warped, cracked, or misshapen
4. Making sure the replacement flapper creates a tight seal

3. The button assembly is worn out and needs replacement
Try cleaning the button first. If that doesn’t resolve the issue, the entire push button mechanism will likely need replacement.

Why is the flush mechanism on my toilet not working?

A Niagara Stealth toilet flush mechanism that isn’t functioning properly is most often caused by:

3. An aged, weak flush valve that doesn’t fully open
