Clogged Drain

One of the most common reasons a toilet won't flush is because the drain is clogged. A clog can be caused by a variety of things, including excess toilet paper, feminine hygiene products, or foreign objects that were accidentally flushed. If you suspect that your toilet is clogged, you can try using a plunger to dislodge the blockage. If that doesn't work, you may need to call a plumber. Be sure to check your drain regularly and clear out any blockages as soon as possible.

A NuvoH2O salt-free water softener can help prevent clogs in your toilet and other plumbing fixtures by reducing the buildup of minerals and other sediments in your pipes.

Faulty Flapper

The flapper is a rubber valve that is located in the bottom of your toilet tank. Its job is to allow water to flow from the tank into the bowl when you flush. If the flapper is worn out or damaged, it may not seal properly, which can cause the water to leak out of the tank and prevent the toilet from flushing.

By reducing the buildup of minerals and other sediments in your toilet tank, a NuvoH2O salt-free water softener can help extend the life of your toilet's flapper.

Low Water Level

If the water level in your toilet bowl is too low, it may not have enough water to create the suction needed to flush properly. The water level in your toilet bowl should be at least halfway up the sides of the bowl. If you find that your water level is too low, you can adjust the float in your toilet tank to increase the water level or call a plumber if the issue persists.

A NuvoH2O salt-free water softener can help maintain the water level in your toilet bowl by reducing the buildup of minerals and other sediments in your toilet tank, which can cause the water level to drop over time.

Broken Handle or Chain

If the handle or chain that connects the handle to the flapper is broken or disconnected, the toilet won't flush. This is an easy fix that can be done by replacing the broken part.

While a salt-free water softener may not directly affect the handle or chain of your toilet, it can help prevent the buildup of minerals and other sediments in your toilet tank, which can cause these parts to wear out faster.


A toilet that won't flush is a frustrating and inconvenient problem, but it's usually easy to diagnose and fix. By understanding some of the most common reasons why toilets won't flush, you can take steps to prevent these issues from happening in the first place. A NuvoH2O salt-free water softener can help prevent some of these issues by reducing the buildup of minerals and other sediments in your toilet tank and other plumbing fixtures, helping to keep your toilet running smoothly for years to come.
