Fix Niagara Stealth Toilet Problems

Each and every toilet faces some common problems, and the Niagara stealth toilet is no exception. It faces some issues that are discussed with possible solutions,

  • Poor flushing 

The water supply valve may be fully or partially closed due to the stain problems, or the intestinal trapways may gather unwanted sludge. The main water supply may face acute obstruction due to some unavoidable circumstances. Sometimes the water level is too low, and the water pressure is not enough for flushing.

Possible solutions: Check the main water supply to see if there is any blockage in the supply valve opening. Clean the toilet by using a snake, auger, or plunger. Fill the tank with the correct water level, check the Lift toilet, and replace the wax ring gasket. 

  • Fill valves keep running

The fill valve may be damaged by excessive debris, or the seal may be damaged. 

Possible solutions: Replace the rubber seal disk and adjust the water lever. 

  • Toilet leakage problem 

The joints of the toilet, like the bolts, water-resistant wax, and washer, may have broken or may have gathered rust.

Possible solutions: The supply line must be rechecked and fixed.

Niagara Stealth Toilet Installation Process

Some people find it difficult to install the Niagara stealth toilet as it is a little bit different type of toilet than the others. Let us have a look into the complete procedure of this toilet,

Step 1: Toilet setup 

Turn off the main water supply and then measure the rough-in. Most of the Niagara toilets have a 12-inch rough-in. Then you need to check out the toilet flange And clear it if there are any types of dirt in it. Apply the T-bolts with brass flat washers. 

Step 2: Toilet bowl installation

Attach the wax ring to the bottom side of the toilet. Apply the scale and check if the bowl is level with the ground. Then it would be best if you tightened the floor bolt wing nuts and the floor bolts to secure the plastic washers’ position.

Step 3: Toilet tank installation

After you have finished installing the bowl, turn your attention to the toilet tank. The tank comes with a rubber gasket that must be joined with the bottom part of the toilet. Tight the washers and nuts to keep the tank stable.

Step 4: Adjust the flush button

The flush button is factory reset with the lid of the tank. Place the button in the proper place and tighten the nuts. The pushrods must be correctly aligned with the top of the flush valve.

Step 5: Installation of the toilet seat

Then attach the toilet seat with the bowl, place the bolts and tighten them up.

Step 6: Connection to the water supply 

Fasten the water supply line and turn on the tap. That’s how you can install the Niagara stealth toilet easily by following some simple steps.
