What water backup coverage is
Water backup coverage is an endorsement you add to your homeowners policy. It helps pay for damage when water or sewage backs up through drains, toilets or floor drains, or when a sump pump fails or is overwhelmed.
Without it, many policies won't pay for this kind of damage, even though it starts inside your home.
Water backup damage can happen fast. A single heavy storm or a clogged city line can push water into a lower level within hours, which is why the risk is worth reviewing before you need it.
What it usually covers
Details depend on your policy, but water backup coverage often helps with:
- Cleanup and drying after a backup
- Repairs to flooring, drywall and finished areas
- Damaged belongings, like furniture and electronics in a lower level
- Damage from a sump pump that stops working or can't keep up
What it doesn't cover
Surface water that flows in from outside, such as rising rivers or heavy rain pooling around the house, is flood damage. That needs a separate flood policy.
Slow leaks and wear are usually excluded too. So is repairing the sewer line itself, which is often a separate service line endorsement.
A claim example
Hypothetical example. Heavy rain overwhelms your sump pump, and two inches of water ruin your finished basement. Cleanup and repairs come to $15,000. Without water backup coverage, the claim may be denied. With a $10,000 endorsement, the policy could pay up to that limit, minus your deductible, and you would cover the rest.
How much to buy
Water backup limits often range from $5,000 to $25,000 or more, depending on the carrier. Match the limit to what's in your lower level: flooring, walls, furniture, a home office or gym, and stored items.
A finished basement usually calls for a higher limit than an unfinished one. Ask your agent how the deductible works for this coverage.
Lower your risk
- Test your sump pump each season and before heavy storms
- Add a battery backup or a second pump
- Consider a backwater valve on your main sewer line
- Keep gutters and downspouts clear and pointed away from the house
- Don't pour grease or wipes down the drain
