What’s Covered?

A home warranty typically covers a plumbing system’s core components, which consist of the following:

  • Drain lines
  • Pipes
  • Sewer lines
  • Toilet components
  • Valves
  • Water lines

Home warranties also cover damage to plumbing components, including the following:

  • Pipe breaks and leaks
  • Plumbing line stoppages
  • Sewer line and mainline clearing within your home’s foundation

Providers offer certain types of coverage, such as septic tank pumping, as an add-on to supplement your plumbing system protection. Additionally, home warranties cover home systems and major appliances.


What’s Not Covered?

According to the Federal Trade Commission (FTC), if a provider doesn’t list an item or component within its service contract, it likely doesn’t cover it. 

There are several conditions or damages a home warranty provider won’t cover regarding your plumbing system. These include the following:

  • Broken or leaking pipes caused by freezing
  • Miscellaneous plumbing system components such as toilet lids
  • Plumbing line stoppages caused by foreign objects or tree roots
  • Sewer line and mainline clogs outside your home’s foundation

We recommend reading a provider’s fine print to understand its exact terms of coverage and exclusions.

Why You Should Cover Your Plumbing System With a Home Warranty

Not only can a home warranty protect your plumbing system, but it can also protect other important systems and appliances, such as your electrical system, heating, clothes washer, dryer, oven, well pump, pool, and spa.

According to our 2021 survey of 1,000 homeowners, over 51% of respondents said their most expensive home costs outside of their mortgage involved repairing or maintaining a system or appliance. Unlike homeowners insurance, which covers damage to your home from natural disasters, fire, or theft, a home warranty protects your most important home items.

Additionally, purchasing home warranty coverage prevents you from paying expensive out-of-pocket costs for unexpected repairs and replacements on home items caused by normal wear and tear. Having a home warranty also saves you from searching for a technician whenever you need a repair. Most home warranty companies have a network of experienced professionals who can repair or replace your broken system or appliance within two to three business days of receiving your claim.

Before deciding on a home warranty, we recommend requesting quotes from the providers listed in this review to help you compare pricing and coverage in your area. Read provider sample contracts to understand contract terms, conditions, and exclusions.
