Sconset lawn, eight zones
Old clock ran every head at once. We split the manifold, recut two laterals, and the well holds through a dry week.

The shop
Who still opens the valve box on Second Way
Three people. Twelve seasons on island wells. David walks the manifold first — pressure, backflow, then the clock. Nobody guesses a zone from the truck window.
- David A Guevara, owner
- Shop at 6 2nd Way, Nantucket
- Well, town, and cistern-fed lawns
Field work
What we actually bury under Nantucket turf
Heads, drip, and the clock that runs them. Salt air and a shallow well change the math — we spec for that, not a mainland catalog.
Zone design & install
New pipe, heads, and a controller sized to the well’s actual gallons — not a guess from the driveway.
Start-up & winterize
Spring charge, fall blow-out. Island freeze hits the laterals first; we clear them before they split.
Controller & sensor repair
Rain sensors, Wi-Fi clocks, broken solenoids. We keep the program, then fix the part that actually failed.
The well first
David still maps the well pressure first
Nantucket water is finite. We measure recovery, then write a zone map that does not suck the well dry at 2 p.m. in August. That is the job, not a prettier lawn brochure.

Field notes
Yards that stopped wasting well water
Short tickets. Real laterals. No invented five-star quotes — the kind of jobs that come back every spring.
Town hydrangea drip
Spray was staining the shingles. Drip under the mulch, rain sensor on the eave, beds stay wet without a puddle on the walk.
Madaket winterize that stuck
Prior blow-out left water in a low lateral. We mapped the sag, added a drain, and the pipe made it through February.
The method
Gauge first, then the shovel
Clear-technical order. The well writes the map. The trench comes second.
-
01 · Recovery
We time the well, not a catalog GPM. If eight heads starve it, the clock gets split before anyone digs.
-
02 · Flags
Laterals marked on the turf. You walk the line with David. Nothing is buried on a guess from the truck.
-
03 · Clock
Program, rain sensor, a live run. You leave with a zone map taped inside the controller door.
Closed tickets
Three island problems we actually close
Well that gasps in August
Too many heads on one station. We recut the manifold and the recovery holds through a dry week.
Spray staining the shingles
Beds go to drip. The walk stays dry. The cedar stops taking a daily bath.
Pipe that splits in February
A sag held water after a rushed blow-out. We map the low, add a drain, and it makes the freeze.
