1. Continuous Running

Glacier bay toilets are water-saving, thus making you more eco-friendly. However, problems may arise, and you find your toilet continuously filling up even after the tank is full of water.

The flapper should be the first component to examine when this issue arises since it may have succumbed to wear and tear. Look for corrosion signs or debris accumulation.

Water will also leak into the toilet bowl if the flush valve is faulty. Furthermore, if the zip tie on your dual flush Glacier Bay toilet break, it will cause it to run uninterruptedly.


Before addressing this issue, cut the water flow into the tank and flush. With that taken care of, do the following

Clear Debris

Over time, debris, dirt, and dust can accumulate, making the fill valve malfunction. In that case, clean and brush the fill valve using a tiny brush.

Fix The Seal or Flapper

Seal or flapper issues are a major reason for continuous running in dual and single-flush toilets. It’s common for this seal to get misaligned or brittle after a while.

Access the seal by removing the canister, then check for any cracks. You’ll need to fit in a new seal if you find damage. 

Also, try to realign the seal if misaligned. Applying petroleum jelly can make it flexible once again and serve you a bit longer. 

Replace the Damaged Zip Tie

The fill valve’s base in a majority of dual flush toilets is held down by a zip tie. Unfortunately, the zip tie can break or wear out before the valve does, leaving it unsecured to the tank, thus making the water run continuously.

Replace the zip tie if broken. Consider using multiple zip ties to ensure the valve is fully secured.

2. Overflowing

This issue can become severe and destructive if left unaddressed, causing water damage and making your bathroom unsanitary. A defective or clogged flush valve and stuck or worn-out flapper can cause this issue.

Moreover, flushing things like pads, tampons, cat litter, dental floss, cotton balls, paper, and other items you are not meant to flush will block the drain, leading to an overflow.


  • Stop water flow
  • Gently press and close the stuck flapper. Alternatively, install a replacement flapper if the current one is worn out
  • Replace a defective fill valve
  • Unclog your toilet using a snake or plunger

3. Leaking

Toilet leaks cause water wastage, potentially raising your water bills significantly. Your Glacier Bay toilet can leak from different locations, such as loose bolts between the bowl and tank, a loose water supply hose, a faulty wax ring, or bowl or tank hairline cracks.


  • If the supply hose is loose, tighten it using adjustable pliers.
  • Tighten the bolts securing together the bowl and tank of a dual-flush Glacier Bay toilet. Be careful not to overtighten them and, in turn, crack the bowl or tank. The tank needs to be emptied, and the water flow temporarily stopped before doing this.
  • The wax ring may have failed if you see a pool of water under the toilet base. In this case, install a new wax ring.
  • If cracks on the bowl or tank are the reasons for the leaks, you have no choice but to buy a new toilet

4. Regular Backing Up

You will understandably panic if you see the rising from the toilet bowl after flushing it because it’s the stuff of nightmares. This problem stems from a clogged drain line, damaged or blocked main line, blocked trap, and insufficient water in the tank.

The waste will not successfully travel down the drain pipes if there’s insufficient water in the toilet tank since that translates to minimal pressure.


  • Temporarily cut water supply
  • Raise the water level. Achieve this by rotating the toilet’s adjustment screw clockwise, thus raising the float’s height and allowing more water to enter the tank. Additionally, tighten the chain if it’s too long
  • Remove sediment buildup in the tank using a drain cleaner or lime remover
  • Unclog the trap using a toilet plunger or a toilet auger
  • If the issue is a clogged main line, let a professional handle it because you could make the issue worse
  • Maintain a regular toilet cleaning routine to eliminate debris from building up in your toilet drain before it becomes severe

5. Self-operating Flush Valve

The flush valve may be leaking if it turns on and off unprovoked. Confirm this by pouring food color inside the tank, then leave the toilet unused for a few hours. If the water in the toilet bowl turns the color of the used food color, then the flush valve is leaking.


  • Replace the flush valve

6. Poor Flush

Subpar flushing can be caused by a myriad of things, including low water level, a faulty or blocked flush valve, stopped rim jets and jet flush holes, and a partially clogged waste pipe. Mineral deposits like calcium and lime compromise a toilet’s flushing capabilities by restricting the proper flow of water into your Glacier Bay toilet.

Water flows slowly down the drain in a partially clogged waste pipe.


  • Elevate the toilet’s float by rotating the adjustment screw right
  • Adjust the chain to a comfortable tightness to achieve proper slack
  • Remove the debris blocking the flush valve, and if this component is worn out, replace it
  • Clean the rim jets and jet flush holes, ensuring anything debris blocking them is removed. Doing so ensures the water flows into the bowl properly
  • Unclog the drain pipes using a snake or plunger

7. Loose Lid

Your Glacier Bay toilet lid will come loose if the hinge keeping it in place runs loose or breaks.


  • Tighten the screws or reattach the hinges
  • Buy a new toilet lid if the above solution doesn’t work

8. Popping Noise

If your toilet produces a popping sound upon pulling the lever down, then the toilet’s system has air. A clogged toilet line can also cause it.


  • Release the trapped air by pushing the lever up and down many times
  • Unclog the toilet line

9. Cracked Tank

Depending on the severity of the crack on your toilet tank, the consequences can be mild or severe. The tank holds water, and a tiny crack can easily flood your bathroom.


You can fix small cracks. However, cracks larger than hairline fractures call for toilet tank replacement.

How to Repair A Cracked Toilet Tank


  • Putty knife
  • Silicone plumbing epoxy ensure it’s waterproof
  • Hair dryer
  • Caulking gun
  • Sponges, towels, and chamois cloth


a) Stop Water Flow

It’s paramount to temporarily stop water flow into your toilet when conducting repairs to avoid creating a bigger mess. So, close your home’s main line or the toilet’s shut-off valve.

b) Dry The Tank’s Interior

The sealer you will use to block the cracks on your Glacier Bay toilet tank will not dry if the tank is wet. Therefore, dry its interior thoroughly using absorbent materials like a towel, sponge, or chamois cloth.

Besides the tank’s inside parts, wipe the exterior as well to prevent condensation. You can even dry your toilet tank with a hair dryer once you wipe off the water with a sponge or cloth to ensure it’s completely dry.

c) Fill the Cracked Area With a Plumbing Epoxy

Buy an epoxy sealer online or from a plumbing store. Other porcelain sealers will also work but perform research to determine the best sealer.

Begin applying the sealer on the cracked area, starting an inch above it, then proceeding downwards, ensuring you cover the entire crack.

d) Spread Out the Sealer

Evenly spread the sealer using a putty or paper knife. Doing so helps protect other parts from cracking and maintains your toilet’s pleasing appearance.

e) Let the Epoxy Dry

The silicone epoxy will take time to dry, so wait for a minimum of 24 hours.

f) Restore Water Flow

Confirm that the silicone epoxy is completely dry and the crack sealed. Also, inspect the tank for cracks that may have appeared during the drying period.

If everything is in order, restore the water supply.
