Slab leak guides

Start here if you suspect water is leaking under your floor. These guides explain how slab leaks show up, how they are confirmed and located, and how the repair choices compare, written for Anaheim Hills homes on concrete slabs.

  • Slab leak warning signs

    A leak under a concrete floor rarely announces itself with a puddle. These are the clues Anaheim Hills homeowners most often notice first, what each one suggests, and how urgent it is.

  • The water meter leak test

    Your water meter can tell you whether water is leaving the house when nothing is running, and one valve at the water heater tells you which side it is on. Here is how to run the test properly.

  • Hot line vs cold line slab leaks

    A house has two separate supply systems under the slab. Knowing which one is leaking narrows the search, changes the clues you will see, and shapes the repair conversation.

  • What causes slab leaks

    Copper under a concrete slab can fail for several reasons, and often more than one is at work. Understanding the usual suspects helps you judge whether a leak is a one-off or the start of a pattern.

  • How slab leaks are located

    Good leak detection is what keeps a slab repair small. This guide explains the tools a plumber typically uses, what each one is good at, and what a detection visit should leave you with.

  • Spot repair vs reroute

    Once a slab leak is located there are two common repairs: fix the pipe where it broke, or bypass it with new pipe through the walls or attic. Here is how to weigh them for your house.

  • When a slab leak means it is time to repipe

    A repipe replaces most or all of a home's water supply lines, usually overhead. It is a big job and sometimes the right one. Here is how to tell the difference.

  • What drives the cost of slab leak work

    Slab leak prices vary too much from house to house to quote fairly. What you can understand is which factors push a bid up or down, so you can compare quotes on equal terms.

  • Find and close your main water shutoff

    When a slab leak starts surfacing, the main shutoff is the one valve that stops it. Find yours now, while nothing is wet, and make sure it turns.

  • Slab leak repairs and permits in Anaheim

    Permit rules depend on the scope of work and can change, so this guide does not tell you what your job needs. It tells you how to find out, who is responsible, and why it is worth getting right.

  • Slab leaks and homeowners insurance

    Only your policy and your insurer can say what is covered. What this guide can do is explain how a slab leak claim is commonly divided up and help you document it well from the start.

  • Questions to ask a plumber about a slab leak

    Slab leak work hides inside your floor and walls, so the conversation before the work is where you protect yourself. Take this list to every plumber you talk to.

  • After the repair: concrete, drywall and flooring

    The plumbing fix is only half the job. Here is what is usually left behind by a spot repair or reroute, who typically handles each layer, and how to avoid gaps between trades.

  • Water damage from a slab leak

    Water from a slab leak comes up from below, which makes it behave differently from a burst pipe overhead. Here is what to expect in each kind of flooring and how to keep a wet house safe while it dries.

  • Pinhole leaks, hard water and copper pipe

    Pinhole leaks are tiny holes that form through the wall of copper pipe. Under a slab they are one of the more common leak types. Here is what they are, what may contribute, and what one means for the rest of your plumbing.

  • Leaks that look like slab leaks

    A moving meter and a high bill do not automatically mean the slab. Several cheaper, easier problems produce the same clues. Rule them out first.
