Slab Leak Detection and Repair in the Perris Core
Downtown Perris — the historic core along D Street and 4th Street, and the surrounding residential neighborhoods extending toward Val Verde — is one of the oldest developed areas in the city. Homes here range from 1940s and 1950s construction through later infill development, with a significant share of copper plumbing that is now 40 to 70 years old.
Copper at that age in Perris is past its expected service life under the area's specific water and soil conditions. EMWD water at 790 PPM total dissolved solids and 12.8 grains per gallon hardness accelerates mineral scaling and pinhole corrosion inside copper lines. Expansive clay alluvium in the soil compresses and moves pipes from the outside. The combination makes slab leaks in older Downtown Perris homes one of the most common calls we receive.
What Changed in Downtown Perris Water Service in 2024
On October 15, 2024, EMWD absorbed the City of Perris water system and began operating all water service in Downtown and North Perris directly. If your home was previously billed by the City of Perris for water service, you are now an EMWD customer. Any paperwork or billing account references from before October 2024 may be outdated.
This matters specifically for slab leak billing adjustments. EMWD's concealed leak adjustment program applies to all qualifying EMWD customers, including those recently transferred from the City of Perris system. We prepare this paperwork for every customer at no extra charge.

A 1960s home in Perris with original copper plumbing is past the expected 50-year copper lifespan under Perris water and soil conditions. If you have not had a slab leak yet, the pipe is statistically in the failure window. The question is usually not whether a leak will occur but when and where. If your EMWD bill is unexplainably higher than previous months, that is a reason to have the line pressure-tested.
We prepare the EMWD concealed leak billing adjustment paperwork as part of every qualifying repair. You submit it directly to EMWD. The adjustment is based on the water usage during the period the concealed leak was active. We can walk you through the submission process at the end of the repair appointment.
