You might not think about this when you go to the bathroom, but the flushing toilet has made life a lot easier. Just imagine having to go outside every time you needed to go to the bathroom, no matter what the weather or temperature. Fortunately, flushing toilets have been around for hundreds of years making our lives much more convenient. While a toilet is a fairly simple mechanism, a problem with your toilet could lead to higher water bills, water damage or even health problems if contaminated water were to leak out.
If you are concerned with water usage, you might want to look at upgrading to a more modern toilet that uses less water per flush. If you have any leaks around your flushing mechanism, you might be wasting a lot of water over time.
Any cracks in the bowl or tank will require a toilet replacement, especially since this could mean that contaminated water will leak out on your floor.
