Cast Iron Pipe Failures: When Your Insurance Won’t Cover Damages

Cast Iron Pipe Lawsuits

If your insurance company balks at covering a cast iron pipe failure, you might need to consider a lawsuit

What’s that weird smell? That crack in the wall is new, right? Or, worse... why is there a puddle in my house? If your home was built before 1975, you might have cast iron pipes that are beginning to crack and cause problems. Hopefully, your insurance company is cooperative, but often they aren’t.

People used to say that homeownership was the American Dream.

While that might still be true for some people, there are parts of homeownership that are not so glamorous. A house requires regular maintenance, which is more than mowing the lawn and cleaning. For instance, you also might need to replace furnace filters, update appliances, and replace components like a roof or siding, which can be expensive and require expert installation.

One thing you probably don’t think about unless it becomes a problem is your plumbing system. A network of unseen pipes run silently through your walls and ground giving you water when you want it and letting it drain away when you’re done. And as long as the water flows, there’s little reason to worry about them.

But sometimes the water flows too much — in other words, a pipe failure can mean drain backup, slow draining, severe leaking, water damage, and expensive replacement costs.

Cast iron pipe failure

Many older homes, particularly homes before 1975, were built with cast iron plumbing systems. At the time, the durable pipes were anticipated to last 80 to 100 years and be able to withstand heavy pressure. In the 1970s and earlier, plastic or PVC pipes—which are standard in most homes built today—were not yet invented and available.

However, now decades later, homeowners nationwide are finding out that their cast iron pipes are beginning to fail. The pipes didn’t last nearly as long as expected, and beloved homes are being damaged as a result.

Here are some of the reasons why your cast iron pipes might have failed sooner than you expected:

  • Extreme weather changes
  • Mature trees with extensive roots that could have spread into the plumbing system
  • Types of soil
  • Water quality
  • Corrosion and oxidation (particularly in areas like Florida with salt- and moisture-rich environments)

What damage can cast iron pipe failure cause?

Common problems that result from cast iron pipe failures include:

  • Sewer backups into the house
  • Growth of mold
  • Water damage inside the house
  • Roach or other pest infestations
  • Slow or clogged drains
  • Broken floor tiles
  • Foul smells
  • Exposure to chemical additives, bacteria, pathogens, and other harmful substances

How to spot a cast iron pipe problem

You might already be aware that there’s a problem, especially if you’ve observed the effects of some of the known problems.

Here are some other hints that you might have cracks in your cast iron pipes:

  • Discolored water. If your water sometimes appears brown or yellow, that’s an important sign that your pipes could be damaged, unless you live in a rural area or use well water.
  • Odor. Cracked pipes can result in sewer gas escaping. If you smell sewer gas, there’s a problem with your pipes.
  • Healthy lawn. Yes, you read that correctly. A healthy lawn can be a sign of cracked pipes. It’s unhealthy for a human to come into contact with sewage or sewage gas. But it is a natural fertilizer for plants and grass. If you see patches of grass that look especially healthy (when you haven’t done other things to help its growth), that might be an indicator that there’s leaking sewage underneath.
  • Cracks in the foundation or walls. All houses settle over time, and small cracks that look like hairline fractures can happen. But major foundation cracks can mean that the mainline has a leak that has caused damage.
  • Puddles. If there are puddles of water or sewage in your yard even though there hasn’t been any rain recently, there’s likely a leak underneath that spot.
  • Rodents or insects. When there are narrow cracks in pipes, it’s an invitation for rats, cockroaches, sewer flies, and other undesirables to enter your home. Certainly, there are other causes of infestations, but if you’ve ruled out other causes, this is one to examine.

Unfortunately, it’s difficult to diagnose a pipe problem because they’re usually inside walls, underground, or in crawl spaces. They’re not easily visible, and you usually need a plumber to come in and take a thorough look.

Real Life Example:A Florida government official says more than 28,000 lawsuits were filed in 2016 for damage related to cast iron pipes.

A total of 860 lawsuits over water damage were filed against the state-run Citizens Property Insurance Corporation in a single month. Of those, nearly half went to court.

In 2018, the Citizens Property Insurance Corporation changed a policy that limited water damage repair payments to a $10,000 maximum unless a homeowner would agree to use the company’s own contractor network for all repairs. In other words, you would use the contractor of the company’s choice, rather than your own, if you wanted insurance coverage.

The insurance company also created a rule that allows it to deny reimbursements if a water damage repair is made within 72 hours after a claim is reported unless the insurance company has the opportunity to examine the damage first and approve the work.

Homeowners insurance coverage for cast iron pipes

If you have a mortgage, you’re likely required to have homeowners insurance. If you don’t have a mortgage, you probably should have it anyway since it protects you financially from many of those things that can go wrong in a home — i.e. a branch falls on your home, a fire, flooding, and... sometimes, cast iron pipe damage.

But not always.

Many homeowners insurance policies exclude coverage for cast iron pipe failure.

Or, if they do cover it, they might give lower reimbursement for a claim related to cast iron damage. Even insurance companies that claim to cover cast iron damage often find reasons to deny the claims.

Why don’t insurance companies want to pay these claims?

The answer is a simple one:

It’s expensive.

An insurance company makes a profit when its policyholders pay more in premiums than it pays out in claims. You pay your premium with the hope that insurance is not something you’ll ever need to use, but it’s there if you need it for an expensive repair.

Your insurance company also hopes you never have to use it. When it pays out a claim, it’s a deduction from its own bottom line. The occasional roof repair or water damage is probably going to cost less than what you pay the insurance company over a few years, but here’s where cast iron pipe replacement is more expensive:

Cost to replace plumbing in a 15,000-square-foot home $8,000 to $10,000
Add water damage + $10,000 to $30,000
Rebuilding from water damage + $5,000 to $15,000
Potential cost for cast iron pipe damages Up to $50,000

Additional damages associated with cast iron pipe issues

The cost of cast iron pipe failure could be much more than the actual plumber’s bill for repairs. In other words, there might be other losses associated with this problem that aren’t immediately obvious, such as:

  1. Depreciation. If you don’t fix the problems related to mold, infestations, and water damage, they will lead to more extensive damage that could reduce the value of your home when it’s time to sell (or make it unsellable) or even make it uninhabitable.
  2. Small problems become big problems. A small line crack is likely to spread and become worse over time as cast iron deteriorates. You’ll need to fully repair or replace a cracked cast iron pipe because it can’t be patched.
  3. Pollution. A broken pipe can spread pollution through underground water sources, which means you could be making other people’s homes unsafe. If you’re aware of the problem and it’s not fixed, you could be liable for their damages.
  4. Health consequences. Class 3 water, also called black water, is dark, dirty water that could enter your home if your pipes are broken. It contains sewage, bacteria, and fungi. It’s not safe to use for any reason. If this water backs up into your home, it can cause serious health problems.

What if your insurance doesn’t cover repairs?

So many homeowners have discovered problems with their cast iron pipes that insurance companies are beginning to decline the claims. That’s why some newer insurance policies are excluding coverage for cast iron pipes, or they increase the cost for policies that include them.

If you’ve filed a claim for a broken cast iron pipe, the insurance company should send a plumber or engineer to your home to evaluate your claim. You might also consider hiring your own expert to provide a second opinion so that you can have more than 1 estimate for the cost of repairs.

Your insurance company is obligated to provide an explanation of how they’ve calculated their insurance payout offer or for why your claim is denied. If the company undervalues or wrongfully denies your claim, you’re left with an expensive repair and no options.

Often, the reasons why cast iron pipe claims are denied is because of a lack of evidence to support the claim, or because the insurance company says the homeowner had an inadequate inspection of the pipes when they purchased the home.

Here are some other examples of what an insurance company might do to avoid paying your claim:

  • Falsely claim that your policy doesn’t cover cast iron pipe damage (or your related damage)
  • Fail to properly inspect the property
  • Undervalue the claim (i.e. make you a low offer)
  • Refuse to investigate the claim or provide an inspection

These practices are known as insurance bad faith.

Fortunately, there are ways to avoid being a victim of bad faith. An insurance recovery lawyer can help you to obtain the damages you need to repair your home.

Your lawyer will:

  1. Send an independent inspector to assess the extent of your damage.
  2. Consult plumbing and engineering experts.
  3. Provide an estimate for the total cost of your damages (i.e. what your case is worth).
  4. Gather evidence and information in order to build a strong case.
  5. File a lawsuit against the insurance company if it can’t reach an appropriate settlement.

Call a lawyer before you call your insurance company

It is important to contact an insurance company quickly when you discover the damage. That’s because if the damage “sits” too long, the insurer could deny coverage because it could claim that you didn’t make the repair soon enough.

But the insurance company might also manipulate the facts in order to find a way to deny your claim. That’s why if you have significant damage, you might want to call your lawyer first.

Your insurance company might try to say that the damage is from ordinary wear and tear or failure to perform routine maintenance, or that the damage wasn’t sudden and accidental, was preexisting or lasted longer than 14 days, or that you don’t have the correct coverage for your issue.

But your lawyer will be ready for these excuses and can negotiate with the insurance company so that they don’t negatively impact your payout.

A plaintiff’s insurance lawyer will be able to advise you of your options, including the steps to take in order to fix the problem without jeopardizing your payout and what to do if the insurance company won’t provide compensation.
