Case Study

Locate Before You Cut: How Kingdom Plumbing Found a Hemet Slab Leak 10 Feet From Where Everyone Assumed

Dan August 16, 2026 2 min read

Water was pooling near a kitchen sink in Hemet. The tenant was sure they knew why — and wanted the floor cut open right there, right now.

Kingdom Plumbing's Clarence stopped them.

First question he asked: has anyone actually located the water lines? Not guessed. Located. The answer was no. So nothing got cut.

Here's the thing about a slab leak — the wet spot on the floor tells you almost nothing. Water travels. A pipe can be leaking ten feet from where the moisture actually shows up. Cut where the water looks like it's coming from, and you've opened the wrong section of concrete for nothing — more mess, more cost, and the real leak is still running.

Over the weekend, the property owner brought in a professional locator. The result: the cold water lines were running under the kitchen sink — nowhere near the spot the tenant had pointed to. Monday morning, Clarence chipped the floor at the confirmed location. Had the tenant run the water to verify the leak in the footing before doing anything else. One opening. Right spot. No wasted concrete.

Both cold water lines running up through the footing got eliminated — not patched over. New copper supply piping went in to feed the kitchen faucet and an adjacent fixture, properly supported, pressure-tested, and cleared in one visit. 3-4 days start to finish. Zero callbacks.

The customer was also offered a whole-house PEX-A repipe while the crew was already in — all lines replaced, hot water piping insulated, documented pressure test at the end. Financing available on approval.

27 years of commercial and residential plumbing experience comes down to one rule that doesn't bend: locate before you cut. Guessing costs the homeowner money and costs the plumber trust. Kingdom Plumbing doesn't guess.
