There are times when you have a problem with sink overflow. This overflow is usually from a clog that has occurred within the drain and the water has nowhere else to go but over the lip of your sink. Even with the sink vent open it may not contain the amount of water that has been backing up.
Hidden Danger in Homes
A sink overflow is one of those dangerous things that can happen in a home that many people do not think about. When a sink overflows, it is usually a race to get some towels to soak up the water. However, there are plenty of other things that are going on under the surface of the floor that the towels can not touch. This is a hidden danger, because people only react to the parts that they can see.
Number 1: Weakening of Joists in Floor
One of the hidden dangers of a sink overflow is that the water can weaken the integrity of the floor joists. The water, once it gets under the floor covering, then sits on the subfloor and joists. It does not evaporate because there is not where for the water vapor to go. So, it sits on the wood and continues to rot it out.
Number 2: Mold and Mildew Growth
Possibly the largest danger of a sink overflow is the potential for mold and mildew to grow. If the right circumstances are present then this can happen very quickly. Mold is a very dangerous fungus that can cause severe respiratory problems in people of any age. Many people become sick living in a mold infested home. Once the mold begins to grow, it can spread quickly throughout the area if not abated. If you have a problem with the sink overflowing often, then you will only add to the mold problem.
Number 3: Leaks To Rooms Below
Another danger associated with a sink overflow is the damage that it can done to the rooms below the overflow. If you have a second floor bathroom that is over the top of the kitchen, then the problem is doubled. Not only will the ceiling on the kitchen begin to leak, but you will be giving many different germs and bacteria access to your kitchen.
Number 4: Potential Safety Hazard
Because there are many different floor coverings in bathrooms, kitchens, and laundry rooms, there is another potentially dangerous situation in the event of a sink overflow. A floor that has some water on it can turn slippery very quickly. Most of the time a non-slip floor is used in areas where there are sinks or tubs. However, some homes have vinyl, tiles, and other floor coverings that can be slippery with some water on them. As the sink overflows, anyone stepping onto the floor may fall. Especially if the person is unaware of the overflow.
Number 5: Repair The Hidden Dangers
In a home where the sink has overflown its bowl, or has a problem with backing up, you should make sure to take care of the hidden dangers. Check for mold periodically. Test the strength of the joists. And look for signs of stains on the ceilings below the sink. If you see any signs of these problems, repair them immediately.
