2. How can I determine why my toilet isn’t flushing properly?

  • The most common causes for a weak flush / poor flush:
    • Clogged sewer line or toilet bowl clogs.
    • Clogged vent line.
    • Incorrect settings or worn out toilet parts.

    2.1 Clogged sewer line or clogged toilet bowl

    Symptoms: When flushing, the toilet’s water level would rise in the bowl and slowly drain. This is a telltale sign that your toilet is clogged.

    Solution: Try plunging your toilet or using a closet auger to see if the stoppage can be dislodged. If you are unable to remove the blockage, you may need to contact a local plumber for assistance.

    2.2. Clogged vent line

    Symptoms: You notice that your toilet gurgles or that bubbles blow out during the flush, or you just get a weak flush that may leave materials behind in the bowl.

    Every appliance that drains into the sewer line has a vertical vent line that allows air to enter the pipe. (These are the pipes that are sticking up thru your roof) The vent must be open to allow air to come in behind the water and waste as they flow through the pipes. Without the air coming in through the vent, a vacuum is created by the water flow. The vacuum slows down the flow of the waste, which can cause solids to settle out and cause a line clog. There are many reasons why a vent pipe would get clogged, including:

    • A previously clogged sewer pipe may have allowed solids to back up into the air vents. When the clog was cleared, materials stayed lodged in the vent pipe.
    • A snow and ice storm may have allowed an ice cap to form, closing off the pipe.
    • A squirrel or bird may have decided the pipe was a good place to build a nest, or store food.

    There is a simple test that you can run to verify you have a clogged vent pipe. Take a large bucket of water and pour it quickly into the toilet bowl. If the vent pipe is clear, the water will go down the drain as fast as you can pour it. If the vent is clogged, the water level in the bowl will rise as the vacuum forms. Stop pouring if the water level rises, as we don’t want to overflow the bowl.

    Solutions: Whatever is obstructing the vent pipe needs to be removed. The easiest way to do this is to take a garden hose up onto the roof, and run water down into the vent pipe. This water will force the obstruction down into the sewer pipe, clearing the vent. Because of the risk of fall, you may want to hire a professional to do this.

    2.3Incorrect settings or worn out toilet parts

    Symptoms: When you flush your toilet, the flush seems very weak or it flushes well every other flush.


    Incorrect Settings: The water level in the tank should be about ½ inch below the top of the overflow tube. The chain on the flapper should only have 1 or 2 links of slack and the black refill tube from the fill valve, should be flowing water into the overflow tube during the refill.

    Worn out parts: A worn out flapper, fill valve, trip lever or flush valve may be causing the flushing problem.

3. How do I know if I need replacement parts for my toilet?

Most toilets have only 4 components that may need to be replaced if the toilet doesn’t shut off.

  • The flapper
  • The flush valve
  • The fill valve
  • The trip lever

The first step is to determine where the leak is occurring. There is a simple “no tools needed” test to determine which part is causing the problem.

  1. Allow the tank to fill, then close the water supply at the shutoff valve. Mark the water level inside the tank, and let sit overnight. If the water level drops, it is either a problem with the flapper or with the flush valve.
  2.  To determine if it is the flapper or the flush valve, hold the handle down so the water level in the tank goes out to the level where the flapper and the flush valve meet. Let it sit overnight.
  • If the water level does not drop, the problem is with the flapper. See our FAQ titled: How to replace a rubber flapper.
  • If the water level drops to the bottom of the flush valve, where it meets the china, the gasket at the base of the flush valve is bad. See our FAQ titled: How to replace a flush valve on a two piece toilet.
  1. If the water in Step 1 did not drop at all, the problem is most likely with the fill valve. Other symptoms that help confirm the problem is with the fill valve include: Water is going over the top of the overflow tube on the flush valve.
  • It might be hissing or continually dripping from the end of refill tube into the overflow tube on the flush valve.
  • If the water is not filling the tank at all, or is filling in erratic starts and stops, it is possible you have debris in the valve. For this symptom, cleaning the fill valve may eliminate the symptom.
  1. Erratic flushing may also occur if the trip lever is wearing out. Replacement should solve the problem.

4. How do I replace a rubber toilet flapper?

For non-dual flush toilets

  1. Turn water off to the toilet at the angle stop on the water supply line.
  2. Carefully remove toilet tank top, and place in a safe location to prevent breakage.
  3. Flush toilet and hold the handle down until water stops flowing out of the tank and into the bowl.
  4. Disconnect flapper chain from trip lever arm (note which hole the chain is connected to).
  5. Gently slide the arms of the flapper off the plastic pegs on the flush valve assembly.
  6. Remove old flapper from the tank.
  7. To install new flapper, gently slide flapper arms over pegs on flush valve assembly.
  8.  Connect the chain to the trip lever arm, and move the clip on the chain so it has a little slack in it when the flapper is in the closed position. Use same hole on the trip lever arm as old flapper was connected to. Note: depending on the flapper for your model toilet, the clip my look slightly different than this photo.
  9. Turn water back on and when tank is full, test flush the toilet to make sure flapper operates correctly.
