Leaks often start small, but the damage grows quickly. We recommend regular plumbing inspections—especially for homes over 20 years old or those with older galvanized or copper piping.
Simple habits help too:

  • Check water pressure annually (ideal range: 50–70 psi)
  • Inspect under sinks monthly
  • Watch for water bill spikes
  • Install a smart leak detector near your water heater

For ongoing peace of mind, ask about our Plumbing Maintenance Plan—it includes annual inspections and discounted emergency service.

Whether your leak is under the slab, behind the wall, or in the yard, LeadingEdge Plumbing & Rooter can find and fix it quickly. We’re based right here in Sylmar and on call 24/7 for emergencies.
