El Cajon Sprinklers arranges spray to drip conversions in El Cajon and East County through local irrigation contractors. A conversion keeps the existing valve and supply pipe and replaces the spray heads on a zone with a drip system, usually because a lawn is coming out, or because a shrub bed on spray heads waters everything except the shrubs.
Converting a zone runs $1.50 to $4.50 a square foot; leaving spray heads in a bed that no longer has lawn means overspray onto walls and paths every watering day, and the runoff and wet footings that lead to $100 to $400 repair calls.
$1.50 to $4.50 per square foot
Converting a spray zone to drip in El Cajon typically costs $1.50 to $4.50 a square foot, or $300 to $1,200 per zone (HomeGuide, February 2026). Reusing the valve and lateral pipe keeps it toward the low end; replacing an old valve or adding a filter, regulator and new tubing runs pushes it up.

- A former lawn now planted with shrubs, still watered by lawn heads
- Spray heads that wet the stucco, the fence or the walkway
- A narrow parkway strip between sidewalk and curb
- Heads hidden by plants that have grown up around them
- Beds where spray water beads and runs instead of soaking in
What a conversion actually changes
At the valve, a filter and pressure regulator are added, since drip runs at a fraction of the pressure spray heads need. Each spray head on the zone is either capped below grade or replaced with an adapter that feeds half-inch tubing. From there the tubing runs to each plant, with emitters sized to the plant.
The supply pipe in the ground usually stays. That is what makes a conversion cheaper than new drip from scratch, and it is why the condition of that pipe is the first thing worth checking. A conversion on top of a cracked lateral simply moves the leak.
After the lawn comes out
Lawn removal is the most common reason for a conversion here. A lawn zone usually has more heads and more flow than the new planting needs, so a converted zone is often split, or some heads are capped, to keep the drip pressure in range. SoCal Water$mart runs a turf replacement program for removing lawn; check its current terms and pre-approval steps before the lawn comes out, since the program sets its own conditions.

Call (619) 361-7869The 24-inch strip along hardscape
The state's water efficient landscape ordinance does not allow overhead spray within 24 inches of a non-permeable surface on permitted projects. Even where it does not apply, that strip along driveways, walks and walls is where most runoff in La Mesa and El Cajon front yards starts, and it is usually the first part of a yard worth converting.
Soil makes the case
The USDA survey maps central El Cajon as sandy loam over a clay subsoil that takes water at about three hundredths of an inch an hour; Santee and Spring Valley sit on Diablo clay. A fixed spray head applies about 1.5 inches an hour. Drip applies water slowly at the root, so it soaks in rather than sheeting off, and the plant gets the water the bill pays for.

How much does it cost to convert sprinklers to drip in El Cajon?
Typically $1.50 to $4.50 a square foot, or $300 to $1,200 per zone. Reusing the existing valve and pipe keeps it toward the low end.
Can I convert just one zone?
Yes. Each zone converts separately, with a filter and pressure regulator added at its valve.
What happens to the old spray heads?
They are capped below grade or fitted with adapters that feed the drip tubing. Nothing is left spraying.
What are the signs a zone should be converted?
Overspray onto walls and paths, a former lawn now planted with shrubs, heads buried in plant growth, and water that runs off before it soaks in.
Is there a rebate for removing my lawn?
SoCal Water$mart runs a turf replacement program. Check the current amount and pre-approval steps before any lawn is removed, because the program sets its own conditions.
Often done together
- Drip irrigation installationWater at the root, not on the wall: drip for beds, shrubs, trees, vegetables and anything on a slope.
- Rotating nozzle retrofitThe same heads, a slower nozzle, and water that soaks into clay instead of running down the gutter.
- El Cajon Sprinklers: Sprinkler Repair in La MesaOlder front yards, shallow soil over clay, and a lot of lawn that is turning into planting beds.
