About this site
Slab Leak Guide explains hidden plumbing leaks for homeowners: slab leaks, water heaters, water service lines, and sewer lines. It is an independent publication. We are not plumbers and we don't sell plumbing services ourselves.
Our process. Articles are drafted with AI assistance, then fact-checked against the sources listed under each article. Cost figures appear only with a source. No fake reviews, no invented authors.
Our illustrations. Some articles use AI-generated illustrations, such as a cutaway of pipes under a slab, to help you picture where a leak can hide. They are not photos of real homes, jobs, or people. Each is reviewed before publishing, and the article says when it uses them.
Our income. Some pages show a number that connects to independent plumbing providers; we may be paid per call. See the disclosure.
When to call a licensed plumber
Water spreading across a floor, a warm spot on a slab floor, a leaking water heater, or sewage backing up into a drain needs a licensed plumber. Keep away from water near outlets or appliances, and shut off the water at the main valve only if you can reach it safely. If you smell gas near a gas water heater, leave the house and call your gas utility or 911 from outside. Never plug or cap a water heater's relief valve. Before anyone digs in your yard, call 811.
