Why Doesn’t My Toilet Completely Flush!?

Does your toilet not empty completely when you flush? If this happens to you, you may find yourself flushing the toilet twice to completely rid of all the contents within. This is annoying, wasteful and not to mention gross. There can be a few explanations as to why your toilet doesn’t completely flush.

New toilets are required to use only 1.6 gallons of water per flush. Although this is a dramatic decrease from the five gallons of water used to flush older toilets, it’s common for the water level on toilets to be set too low. When the toilet water level is set too low, there isn’t enough water for the toilet to flush completely. If you suspect this is the case with your toilet, you’ll need to adjust the level of the water by adjusting the arm of the float ball or turning the float adjustment screw of the floating cup ballcock clockwise.

If the chain on the flapper has become caught, it won’t be able to release all the water that is needed to flush the toilet. Remove the lid of the tank to see if there is an issue with either the flapper or the chain attached to the flapper and make the proper adjustments or necessary replacements.

Once you’ve checked both the water level and your flapper and there is no problem, there is a good chance that you have a clog on your hands. A clog, even a minor one, will keep your toilet from flushing completely. First try some plunging, if this doesn’t work head to your local hardware store for a snake to see if you can unclog the toilet.

Should neither plunging or snaking work, call in a professional, there could be a few other reasons as to why your toilet is not completely flushing. This problem could be a result of blocked inlet holes, or an issue with how the toilet drain pipe was designed.
