Most irrigation systems are repaired well past the point where repair makes sense. The test is not whether the next fix is cheap — it is whether the system as designed can water the landscape you have now.
Repairs that are always worth doing
Broken or sunken heads, heads knocked out of alignment, and nozzles worn or wrong for the zone.
A single failed valve or solenoid, a controller that has lost its programme, or a broken wire.
A leak in a lateral line, showing as a wet patch or an unexplained rise in the water bill.
These are maintenance items on an otherwise sound system, and none of them argue for replacement.
Signs the design, not the parts, is the problem
Dry arcs and soaked strips in the same zone every cycle — that is spacing and head-to-head coverage, and no amount of nozzle swapping fixes it fully.
Lawn and beds sharing a zone, so one is always over- or under-watered.
Zones so large that pressure drops and heads mist rather than throw.
Sun and shade areas on one valve. Different exposures need different run times.
These are original design problems, and they get solved by re-zoning, not by repair.
When the landscape has changed
A system laid out for an open lawn twenty years ago is watering under mature tree canopy today. Coverage that made sense then wastes water now.
New beds, a patio, a pool or a wall built through an old system leave orphaned heads and cut laterals patched into a layout nobody has a plan for.
Converting bed zones to drip is often the single best upgrade on an older system — better for the plants, far less water lost to evaporation and overspray.
Making the call
Repair when the layout is sound and failures are isolated. Rebuild zone by zone when the design is wrong but the mainline and valves are good. Replace fully when the pipe is failing in multiple places, the mainline is undersized, or there is no usable record of what is in the ground.
A modern controller with a rain or soil sensor is worth adding either way; it saves water on a good system and prevents damage on a mediocre one.

Frequently asked questions
How long does an irrigation system last?
Heads and valves are wear items replaced over time; buried pipe can last decades. Systems usually get replaced because the design no longer suits the landscape, not because the pipe failed.
Can I add zones to an existing system?
Often yes, if the mainline and water supply can carry the additional demand. That capacity check comes first.
Is a smart controller worth it on an old system?
Yes for water savings and convenience, but it cannot fix poor coverage. Uneven zones stay uneven, just on a better schedule.
