Water Back-Up, Overflow or Discharge? Homeowners' Claims

8/22/2017 (Permalink)

Last month we talked about how to protect your home from flood damage. Hopefully the tips served you well, but here are some tips on what causes a water back-up or overflow and whether or not there is coverage for such a loss.

Is it a water back-up, an overflow or discharge?

A back-up is a build-up caused by a stoppage in the flow. Something prevents the water from continuing down its path, so it is forced to reverse direction and go back the other way.

• Causes: A collapsed drain pipe can cause a back-up because water can no longer proceed down its normal course. A blockage can also cause a back-up. The blockage prevents the water from going forward. Both of these factors force the water to reverse direction.

An overflow is when excess or surplus is not able to be accommodated by an available space.

• Causes: The space is filled to capacity and water then spreads beyond its limits. A bath tub left running creates an overflow, as well.

Discharge is what happens when water is released from plumbing or appliances and then floods your home.

• A leaking pipe discharges water from the hole in the pipe.

The ISO HO 00 03 provides coverage for water damage that is the result of a discharge or overflow of a plumbing, heating, air conditioning, or household appliance if it is on the resident’s premises. This covers:

• Pipes that leak behind walls
• Floors, or ceilings
• Washing machines and dishwashers that overflow
• Toilets that overflow
• Storm drains off premises that overflow due to high rains or floods

It is important to note that a sump, sump pump or related equipment, or a roof drain, gutter or downspout or similar equipment is not considered a plumbing system or household appliance.

A discharge or overflow caused by a storm drain, water, steam, or sewer pipe is covered as well if it is off the premises.
