Niagara Flapperless Toilets are manufactured by Niagara Conservation which was started in 1977 by William Cutler, like many American businesses it had humble beginnings in the garage at his home. In the thirty years since its start in that garage it has grown providing many innovative products that conserve water and energy. Today the Niagara Conservation is headquartered in Cedar Knolls, New Jersey and has many satellite offices across the US an affiliate company in Toronto, Canada. Their products have gone global and they are sold throughout North America, South America, the Caribbean, Europe, the Middle East, and Australia.
The Niagara Flapperless Toilet is a unique design unlike any other toilet made today. At first glance it looks like any other toilet, there is a bowl and a tank, with a handle on the side of the tank to activate the flush. But when you lift the tank lid and see what it’s got under the hood you will see a radical design that changes everything. This “Flapperless” toilet is exactly what the name says it is. There is a unique fill valve that comes up high in the tank over a “Tipping Bucket” the fill valve fills the “Tipping Bucket” to the prescribed level either 1.6 gallons or, 1.28 gallons depending on the model. When you use the Niagara Flapperless Toilet you simply press the handle on the side of the toilet and the “Tipping Bucket” overturns spilling the prescribed amount of water into the tank where it flows through where a flapper would have been in a regular toilet, down into the bowl causing the toilet to flush. The “Tipping Bucket” then rights itself and refills for the next flush.
This unique Flapperless design effectively cures a toilet maintenance problem that wastes vast amounts of water every year. Flappers on toilets are under attack by chemicals in the water from the first moment they are put into service. Water suppliers use Chlorine and Chloramines to sanitize the water keeping it safe to drink. These chemicals attack rubber components in the toilet tank and typically give them a service life in the area of five years. When a flapper degrades it usually starts to leak and the leaking often goes unnoticed because the water flows through the toilet and into the drain quietly. Only people that change out a worn flapper ahead of time, notice the fill valve refilling the tank without being flushed, or dye test their toilets to detect flapper leaks manage not to waste water.
The unique Niagara Flapperless "Tipping Bucket" design eliminates many of the maintenance issues that cause conventional toilets to waste water.
Niagara Flapperless Toilets are offered in 1.6 and 1.28 gallon per flush models. The 1.28 gallon per flush models meet EPA WaterSense Certification Requirements and are eligible for government and water company rebate programs in many areas of the US and Canada. Check in your area for rebate availability and the program requirements. The Niagara Flapperless Toilets come in round and elongated bowl models, and also many models meet ADA height requirements. In addition the “Tipping Bucket” can be reversed to allow the handle to be on either the right or, left side. The tank to the bowl connection is adjustable so each model’s rough in dimension (distance from wall to the center of the bowl outlet) is fully adjustable from 10 to 12 inches. All models have a large 2” diameter trapway that is fully glazed to help prevent sticking and clogging and they have a large 10” wide X 20” long foot print to provide a stable base and cover the footprint of your old toilet without having to redo the floor because of stains under the base of the old toilet. The large tank should also cover the wall that hid behind your old toilets tank as well avoiding the need for wall repairs. One of the neat things about the Flapperless design is that the tank sweating in periods of high humidity is eliminated because the cold incoming water never touches the tank long enough to make it sweat. All Niagara Flapperless Toilet Models come with a Lifetime Warrantee on the vitreous china parts and a 10 Year Warrantee on component parts. The simplicity of this design should make this toilet a reliable performer with the only parts that wear being the fill valve which is made for Niagara Conservation by Fluidmaster and the pivot points of the tipping bucket. Other than those 2 items there is nothing that moves and can wear.
The Niagara Flapperless Toilet performance has generally been good with MaP Report Testing coming in between 400 and 1,000 grams of solids per flush depending on the model. Niagara makes quite a few different models of Flapperless Toilets under their own name and Home Depot’s names where they are sold as Glacier Bay, and Pegasus Flapperless Toilets. When selecting a toilet, checking the MaP Testing on the specific model is a good idea to ensure that you get a flush performance level you can be happy with.

Love the toilet but it continually runs even after the trough is filled. Have tried adjusting the float but still doesn’t shut it off. Is it the fill valve and how do I get one to replace it? They do not have the parts at Home Depot.
Hi Cleossistah,
When you lift the float on the fill valve all the way up does it shut off? If it does bending the fill valve tube downward until the correct water level in the tray is correct is what you need to do.
If the fill valve does not shut off when you lift the float the fill valve needs to be replaced. To obtain a new fill valve call Niagara.

When flushing, the toliet makes a very “HIGH PITCHED” “EAR SPLITTING” noise that stops once the flush is complete. This does not happen every time but approx. every second flush. Any ideas?
Hi Janet.
This noise could be a couple of different things.
My guess is it’s either the angle stop valve supplying the toilet or the fill valve in the toilet tank.
Try turning the angle stop valve supplying the toilet slightly and see if the sound changes.
See if it is open all the way.

I have to replace the bolt that connects the tank to the toilet. I have the new bolt set. There are two black rubber washers for each bolt one is cone shaped and the other just round. Where does the round one go? Inside the tank or under the tank?
Hi Louise,
The flat rubber washer goes against the head of the screw.

Can you help? We have just installed the toilet Niagra flapperless. We have a 10″ (not 12″) rough in onto our concrete floor.
The tank came with connecting nuts, not the wing nuts stated. Also the inner tank on our model (623.023 tank/622.870 bowl) has two tippers, the top one, then a lower smaller tipper on the lower front inside edge.
The bolts protruding through the tank had washers and nuts factory installed tight to the porcelaine tank base, which we left on initially. When we flushed, water came pouring through the gasket seal even though we had it pretty tightly attached to the toilet base via the bolts. We thought maybe it would work better if we took off the nuts that had been factory installed to give us a tighter “pull down” seal. No difference, the water still pours through the gasket area.
As you know the flush hole from the tank is an oval shape with the gasket factory assembled and glued to the base underside. The hole in the toilet is the usual round hole. Because we are on a 10″ rough in with only just enough room to leave a 1/4th inch wall gap (even though this toilet is meant to serve both 10″ and 12″ rough ins) – there seems to be no part C2216-28 toilet bowl refill funnel on this tank (maybe because it has this lower trough instead???) and from what I can see inside, there is a replica rubber gasket held down with the bolts instead.
We have tried tightening as much as we dare and loosening too and the water cascades out of the gasket seal. My own intuition tells me maybe we have a part missing. Brand new toilet bought from local plumbing supply store.
Ideas??? We would like to fix this so we have a toilet!!!
Hi Liz,
I would contact Niagara Conservation to see what they say.
Your toilet sounds like it has some changes that may have gone into effect since my parts list was printed.
It almost sounds like the oval hole is not sealing properly to me.

Just installed a 1.6 gal Niagara Flapperless 2216 — I should say, tried to install. It is leaking at one of the bolts which attaches the tank to the bowl section. How do you take the bucket out to check the bolt and the way it is sealed? This is one of the bolts that was preassembled on to the tank. It’s not leaking at the gasket –which would be an installation issue. It just seems to be running down the bolt –in a fairly generous stream. Help!
Hi Joy,
With a brand new product and its warranty I would recommend contacting Niagara Conservation.

I have a glacier bay niagara flapperless toilet. The tank leaks on the side where the trough is attached to tank side. The water level in the trough is at the proper level. The water sloshing over must hit the side and leak out of the bolt. Not every flush does this happen. I have tried to tighten the bolt on the inside of the tank.
Any suggestions.

I would recommend contacting Niagara Conservation for Warranty Parts.

We have had a Niagara Flapless Toilet for about 3 years. This past month during the filling process the water flow seems to be pulsating and rattling. We have adjusted the copper tubing and it would work fine for 5 or 6 more flushes then returns to the pulsating. Do you have any other suggestions?
Hi Linda,
I would suggest you try turning the stop valve for the toilet supply coming out of the floor or wall to a different position to see if the noise changes at all. Frequently a loose washer in a stop valve can make a noise almost like a jack hammer when it starts bouncing around in the stream of water going through the valve.
If the noise changes with the valve set at a different position the stop valve will need to be replaced.
If the noise does not change it may also be the fill valve and I would contact Niagara Conservation for parts.
I would check the stop valve first because that is a lot more likely to be the cause.

My handle and bucket stick in the “dump” position and that causes the toilet to run constantly. My 3 year old does not understand to “manually” replace the handle in “off” position. Can it be fixed?
Hi Vicki,
I would recommend contacting Niagara Conservation.
They would have the best advice on what you need to do.

The water filling nozzle is pointing towards the front lip of the tip-bucket instead of straight down. This means that the water delivery is at a 90 degree angle to the up-down swing of the float stem. I looked at how the stem hinge attaches to the rest of the mechanism and there are some visual clues such as two flanges that look as if it might be there to give your fingers purchase to twist the valve swing assembly so that it is in line with the water delivery, but I tried it and it does not rotate.
How can I get the swing of the float to be in line with the downward water delivery?
Thanks!
Hi Peter,
The nut where the fill valve attaches to the copper tube may be loosened allowing the valve to turn.
If the flow of water into the tray is so strong that it comes over the tray or, splashes over your house may have excessive pressure. If you measure your water pressure with a gauge that screws onto a hose bibb or the drain on a water heater the pressure should be less than 80 psi.
Redwood
Hi Redwood,
Yes, when I loosen that fitting, the whole assembly–water delivery nozzle and swing arm with float– rotates, so I need to rotate the swing arm in relation to the nozzle piece, not rotate everything as a whole. Right now I’ve made a compromise and have the float arm swinging at a 45 degree angle and the water output shooting out at a 45 degree angle downwards. Too bad I can’t draw a picture. lol
Here’s a crude sketch:
Water shooting down, arm swinging side to side.
Okay Peter,
I understand what you are saying now. I believe where I added the black arrow to your drawing there is a locking tab connection where tabs fit into slots. You either need to turn the connection until it is fully locked and the orientation is correct or, you need to turn and unlock the connection pull it apart and move the tab to the next slot then put it together and lock it so the orientation at the connection is correct. Of course the water needs to be off when you do this.

My question got submitted in mid sentence. I was going to say is there another place I can put it or some other type of continuous cleaner I could use?
Hi Bonnie,
I’m not sure what happened to your original comment. It didn’t go through to me.
I’m guessing what you are asking about is there is a bowl cleaner that can be used with Niagara Flapperless Toilets.
To the best of my knowledge there is not.
The configuration of the tank does not allow it and the only thing that could be used is one in the bowl which are not something you want to do unless you like paying plumbers to get things out of toilets.
On conventional toilets with flappers the Fluidmaster Flush and Sparkle or, the Kaboom bowl cleaning system are the only in tank bowl cleaners I would recommend. All others use chemicals that can ruin the rubber components of the toilet. The Fluidmaster and Kaboom Bypass the tank and go directly to the bowl so they will not damage the rubber components in the tank. These however cannot be installed on the Niagara Flapperless.
I hope this answered your question Bonnie if there was something else you wanted to ask please repost your comment so I get your full comment.
Redwood.
