Cause of a running Glacier Bay Dual flush toilet

A Glacier Bay Dual flush toilet hardly has any problems, but when it does, the scenario isn’t good. For starters, you will find constant water flow on the floor, and the water bill is going straight to the rooftop. Here are some of the leading causes of a running Glacier Bay dual flush toilet.

Worn out valve

A worn-out valve is a leading cause for old dual flush toilets. If your toilet stood up for six to seven years, then change it without a doubt. Sometimes a valve can wear out if you use too many harmful cleaning agents.

Irregular water level

When the water level is set to maximum, water may sip from the upper lead and into your bathroom floor. The water level should be at least 1-2 inches below the opening. An irregular water level can cause other parts like the valve flapper or seal to wear off before due time.

Toilet seal problem

Is running water forming foam around the base of the toilet? This sign indicates a broken toilet seal. Foul odors, ceiling damage, etc., are the significant signs. If you find water accumulating or puddles around the base, check out the wax ring or toilet seal first.


After you checked the flush valve, try checking the flappers. A loosely resealed flapper lets water flow in the toilet bowl, which causes the running. This problem can be an easy fix if you keep the lift chain short between the flapper and the flush valve.


Sometimes, debris or a cluster of sediment may form in the toilet’s water bowl. As a result, the debris can block your flushing line, causing an overfilled bowl. Debris can also damage the valve, if you don’t clean it every six months. Additionally, you will end up having a running toilet with constant water leakage.

Poor toilet flushing

If your toilet doesn’t flush properly, it may be a sign of debris formation or a broken flush. In any case, water inside the bowl gets overfilled and causes a running toilet. If your bowl doesn’t flush completely, this is a sign of poor toilet flushing.

Leaked pipes

The pipes may break or loosen with time, causing a constant water flow. An easy diagnosis of this problem is the water flowing from the pipe to the floor.

Broken joints

Even after you fixed all the pipe leaks, your pipe joints may start to leak water. Too much pressure buildup can cause this problem to your toilet. Try finding the initial cause of the pressure and then fix the joints.

A long chain

When you have a longer flush chain, the flappers can’t shut down properly. This is why you will find water overflowing into the bowl. Keeping a short-chain can help keep the flappers closed, and the water leaks out.

Float ball

The float ball is the part attached to the valve, which livers the opening and closing of water flow. A damaged float ball will damage the valve and can make continuous running water.
