Do you know what the most common reasons for basement flooding are? You might guess poor drainage or a leaking pipe, and those are common, but did you also consider washer hoses? These might seem sturdy, but you will find that the hose that is delivered with a new washer usually is a cheap hose that might not stand up to the pressure over a longer period of time.
The problem is that many homeowners have a habit of leaving the water on at the water supply for their washer, and if the hose gives, then you have a lot of water streaming into your basement.
So what should you do to prevent this from happening? Well, naturally the first thing to do is to stop leaving the water turned on, but you can also minimize the risk that the hose bursts. There are much better options, such as steel braided hoses that will last you a long time.
