Where leaks show up in San Clemente homes
Copper lines in newer tracts, not just old homes. In 2015 a class action was announced alleging that copper pipe installed in San Clemente-area subdivisions, including Talega, was prone to leaks (PHCP Pros). Whatever the cause in a given house, a first pinhole leak is a reason to check the rest of the system.
Under the slab. Many San Clemente homes sit on concrete slabs with water lines running underneath. A warm spot on the floor or the sound of running water with everything off are typical signs. See how we find slab leaks.
Inside walls and ceilings. Supply lines to bathrooms, kitchens and laundry rooms run behind drywall, and in two-story homes a leak upstairs often first appears as a ceiling stain below.
Between the meter and the house, and on sloped lots. The buried service line and irrigation lines can leak for a long time with no sign indoors except the bill. A soggy patch, or a spot that stays green in a dry month, can point to it.
Check for a leak yourself first
Turn off every faucet, appliance and irrigation zone, note the reading on your water meter, and check again after 30 minutes. If it moved, water is leaving the system somewhere. Our water meter test guide walks through it, and why is my water bill so high? covers the usual causes.
City side or your side?
The City of San Clemente runs its own water utility. A leak in the street, on the city side of the meter, or a sewer overflow goes to the city's 24/7 Utilities line at (949) 366-1553. A leak on your side of the meter is generally the owner's to find and fix. If a leak ran up your bill, the city's Utility Billing Division has a Tiered Rate Adjustment Application that lists plumbing and slab leaks; the form says it offers one courtesy adjustment per 12 months and may ask for proof of repair, so keep your written findings and invoice. Confirm current terms with Utility Billing at (949) 361-8315.

- Electronic pipe locating to trace lines in walls, under the slab and in the yard
- Thermal imaging to confirm hot-water leaks
- Repair once the leak is found, or a slab leak reroute or PEX repipe when that is the better call
- Written findings to bring to your insurer or the city (no coverage or adjustment promises)

Find the leak first, then a straight answer on the fix
Which line is leaking?
Pressure testing shows whether the hot line, cold line or the service line from the meter is losing water, so we know where to look.
Listen, trace and confirm
Acoustic equipment picks up the sound of pressurized water escaping, electronic locating traces where the pipe runs, and thermal imaging cross-checks hot-water leaks. The spot is marked for the smallest possible opening.
Repair, reroute, or repipe
A single leak in a sound line is usually a spot repair. Repeat leaks in aging or failing copper may make a reroute or repipe the smarter call. We explain the trade-offs after diagnosis, never before.

The City of San Clemente runs its own water utility. Leaks in the street, on the city side of the meter, or a sewer overflow go to the city's 24/7 Utilities line at (949) 366-1553. A leak on your side of the meter, in the line to the house, under the slab or inside a wall, is generally the property owner's to find and repair, and that is the part we locate.
The City of San Clemente's Utility Billing Division has a Tiered Rate Adjustment Application that lists plumbing and slab leaks, toilet leaks and irrigation leaks as reasons for high use. The city's form says it offers one courtesy adjustment per 12-month period, that applications are subject to verification of the repair, and that it may ask for repair invoices. Check the current form and terms with Utility Billing at (949) 361-8315. Keep the written findings and the repair invoice; that is the paperwork the city may ask for.
It isn't only an older-home problem. In 2015 a class action was announced alleging that copper pipe installed in subdivisions in the San Clemente area, including the Talega community, was prone to leaks; the builders' side disputed similar claims elsewhere in South County. Whatever the cause, one pinhole leak is a reason to check the rest of the system. We find the leak first, then walk through whether a spot repair, reroute or repipe makes sense.
Common signs are a water bill that rises for no reason, a water meter that keeps moving with every fixture off, the sound of running water when nothing is on, a warm spot on the floor, damp or stained drywall, a musty smell, or a soggy patch in the yard. The simplest check is the water meter test: turn off every fixture and irrigation, note the meter, and look again after 30 minutes.
In most cases, yes. Pressure testing tells us which line is losing water, acoustic equipment listens for the leak through drywall, tile or concrete, electronic locating traces where the pipe runs, and thermal imaging helps confirm hot-water leaks. The goal is one small, targeted opening at the leak, not exploratory demolition.
If you're filing an insurance claim, insurance typically reimburses the leak detection cost. Coverage depends on your policy and the cause of the leak, so check with your insurer. We give you written findings, including the affected line, its location and what we found, to bring to them.
