More yard, more buried pipe

Around Laguna Lake, lots tend to be larger than in typical tract neighborhoods, and some properties have extensive landscaping or space for animals. A longer distance from the meter to the house means more buried service line, and extensive irrigation adds more pipes and valves that can fail.

Home ages vary across the area, from older custom homes to later construction, so plumbing materials vary too. A break on these lots may show up as a wet patch far from the house rather than water indoors.

Where is the leak on a big lot?

  • IfThe meter moves with the house main closedThenThe leak is on the service line between meter and house, or on a line that branches before the main.
  • IfIt stops when irrigation is turned offThenLook at irrigation valves and laterals first.
  • IfA wet strip runs across the yard in dry weatherThenFollow it toward the meter and house; that is likely the service line route.
  • IfWater only appears indoorsThenTreat it like any house break: close the main and isolate.

Large-lot checklist

  • Map the route of your service line from meter to house
  • Know whether irrigation branches before or after the house main
  • Find and label any separate shutoffs for barns, guest units or yard taps
  • Note where large trees sit relative to buried lines
  • Read the meter periodically to catch slow yard leaks

Common questions

Is the longer service line my responsibility?

Typically the line from the meter to the house is the homeowner's. Check with the City of Fullerton if you are unsure.

Can irrigation leaks look like a pipe break?

Yes. Rule out irrigation first by shutting off its supply and rechecking the meter.

Do roots affect long service lines?

Older buried lines near large trees can be stressed by roots. A plumber can suggest rerouting if it keeps happening.
