How To Improve Toilet Flushing Power
When one flush consistently doesn't do the trick, you have a problem. Don't get stuck in the bathroom waiting for the toilet to refill so you can flush it again (and maybe again!). It's embarrassing and unnecessary. There are some things you can try to fix this problem that cost much less than replacing the toilet or assembly parts.
STEP 1: Make sure your toilet isn't clogged.
This should seem obvious, but it may be a smaller less obvious obstruction that is slowing your flush. Check your flow by pouring a gallon of water into your toilet and flushing it. If the toilet doesn’t flush efficiently then you most likely have a clogged toilet. You can unclog a toilet with a standard plunger or snake. If the toilet seems to flush properly then it's time to try step 2.
STEP 2: Check the toilet tank fill line level.
Remove the toilet tank cover to check to see if the water level in the tank is even with the designated line. If the water level isn’t matched up, then adjust the water tank float assembly (located in your toilet tank) accordingly.
STEP #3: Clean the toilet bowl flush holes.
Check the toilet bowl flush holes located around the rim of your toilet bowl. Sometimes these small holes that shoot water out during a flush can get clogged. This decreases the pressure of the water stream when you flush. This is dirty work, but get down on your hands and knees and try using a bobby pin, coat hanger wire or a small drill bit to clear the holes of any blockages. Flush the toilet and check for improvement in power of the flush.
STEP #4: Clean out your toilet using bleach.
Before you do this, make sure to turn off your toilet’s water tank supply. A tube coming out from either the wall or the floor should contain the water supply valve. Turn the knob of the valve to the right to completely shut off the water. Next, pour a gallon of bleach into your toilet bowl and let it sit for 15-20 minutes. After you let the bleach sit, go ahead and flush the toilet. This allows the bleach to naturally work its way through your toilet system, cleaning out any built up blockage that has been reducing the flushing efficiency of your toilet. You may then turn the toilet water supply back on (allowing the tank to fill back up). Over the next 30 minutes, flush your toilet a few more times to thoroughly wash the bleach and unclog the blockage.
STEP #5: Clean out your toilet using vinegar.
The last step to improving flush power is a vinegar soak. First, open the lid of your toilet tank. If there is a rubber fill hose on top of the overflow tube, carefully remove the fill hose. Use a funnel and place it on the tube inside of your toilet tank. Take about a quart of white vinegar and pour it in the tube through the funnel. Let the vinegar sit for at least 2 hours. The vinegar disinfects and helps to loosen junk deposits that have been building up in your toilet system.
If you don’t see a difference after completing these steps and are still experiencing weak toilet flushes, you may want to consider replacing your toilet system. Old toilets are harder to fix on your own and may require a complete replacement or the help of a professional plumber.
