Unfortunately, due to high water-saving efficiency, low-flow toilets don’t have the same amount of power in flushing as regular toilets do. Because so little gallons per flush are used in aow-flow toilets, you’re going to get not as forceful water flow. What this means is that oftentimes, it might take two or more flushes to remove everything. Another reason why your flushes may be weak is because of mineral deposits that can stick to the jet hole. These deposits block the water from rushing through to the bowl, and this can often cause a weak flush. Thus, it’s always important to maintain and clean your low-flow toilet regularly.
