Hidden leak inspection for Daly City homes

If you see active water damage, request a leak inspection the same day. Our crews come to Daly City from Pacifica and San Francisco.

What to know first

  • Start with the city’s free tools. They catch common toilet and fixture leaks.
  • If those come up clean and the bill or the damp spot stays, the leak is likely hidden.
  • We use acoustic, thermal, and pressure testing to narrow it down before opening anything.

Signs You Need a Leak Inspection

Hidden leaks give themselves away in small ways. Call for an inspection if you notice:

  • A water bill that climbs with no change in use
  • The sound of running water when every fixture is off
  • A warm spot on a floor, which can point to a hot water line
  • Stains, bubbling paint, or soft drywall
  • Musty odors in a closet, cabinet, or under the house
  • Low pressure at several fixtures at once

One sign alone can have other causes. Two or more together make a hidden leak likely.

How Our Leak Inspection Works

  1. Review what you have seen. Bills, sounds, damp spots, and the results of any dye test.
  2. Check fixtures. Toilets, faucets, the water heater, and hose bibs, so we rule out the easy causes.
  3. Isolate lines. Pressure tests show whether the leak is on the hot side, the cold side, or the line from the street.
  4. Pinpoint. Acoustic and thermal tools narrow the location.
  5. Report. We show you where the leak is and price the repair before any wall or floor is opened.

We at Works Plumbing aim to open the smallest area possible. A clear location keeps repair and patching smaller.

Where Hidden Leaks Show Up

Location Common clues Typical repair
Inside a wall Stains, bubbling paint, sound of water Open a small section and repair the pipe
Under the floor or in the crawlspace Musty smell, damp subfloor, warm spot Repair from below when access allows
Supply line from the meter High bill, wet yard, low pressure Repair or replace the line
Water heater connections Moisture around the base or fittings Replace the fitting or connector
Toilet flapper Dye in the bowl, refill sounds Replace the flapper or fill valve

If the leak is on the line from the meter to the house, our page on water line repair in Daly City explains the repair options.

Small Leaks Worth Fixing Now

Not every leak is hidden. A faucet that drips all day wastes water and wears its own parts. Our faucet repair in Daly City page covers drips, worn cartridges, and loose handles.

Running toilets and dripping fixtures are the cheapest leaks to fix and the easiest to forget. They are also the ones the city’s free tablets are built to catch.

Leak Inspection in Daly City, CA: FAQs

Does Daly City give out free leak detection tablets?

Yes. The city’s Water Conservation page lists leak detection tablets among the free water-saving devices it delivers to Daly City addresses. Use them to check toilets before you book an inspection.

The dye test passed, but my bill is still high. What next?

The leak is probably not at a toilet flapper. A hidden supply leak in a wall, under the floor, or on the line from the meter is the next suspect, and that needs equipment to find.

What is the city’s Residential Self-Audit Tool?

It is a resource listed on the city’s Water Conservation page to help residents review water use at home. It is a good way to rule out drips and running fixtures before a professional inspection.

Will you have to open my walls?

Only after we have narrowed the location. We use acoustic, thermal, and pressure tests first, then open the smallest area needed for the repair, with the price agreed beforehand.

Should I turn off the city meter if I find a leak?

No. Daly City asks residents not to operate the meter themselves. Use your home’s main shutoff or the valve at the fixture, or call the city’s water department to have the water turned off.

Can you inspect for leaks the same day?

Yes. Same-day service is available in Daly City, and we offer 24/7 emergency service when water is actively damaging the home.

What Daly City’s Free Leak Tools Can Tell You

Daly City gives residents a simple first step. On its Water Conservation page, the Department of Water and Wastewater Resources says it offers free water-saving devices for residents, delivered to Daly City addresses. The order form includes leak detection tablets in a two-pack. The page also lists a Residential Self-Audit Tool.

Here is what those tools do well.

The tablets are a dye test for a toilet. Drop one in the tank, wait without flushing, and check the bowl. Color in the bowl means water is slipping past the flapper.

The self-audit walks you through the house fixture by fixture, so drips and running toilets get noticed.

Here is what they cannot do. Neither tool can see inside a wall, under a slab or subfloor, or along the buried line from the meter to the house. A pinhole in a copper line behind drywall leaves no dye trail and no visible drip.

That is where our inspection starts. When you call, we ask what the tablets and the self-audit showed. If a toilet failed the dye test, it may simply need a new flapper. If every fixture passed and the bill is still high, we move to equipment:

  • Acoustic listening to hear water escaping under pressure
  • Thermal imaging to spot hot water leaks and wet areas
  • Pressure testing to isolate which line is losing water
