Irrigation Frequency

• The interval between irrigationsdepends on the average soil type.Light (sandy) soil should be wateredfrequently with short irrigationduration. Heavy (clay) soils can bewatered less frequently with longerirrigation duration.

• Maximum daily plant requirementsshould be used to establish theemitter spacing in the dripline as wellas the flow rate of the emitters.

• Irrigation time should not exceedthe soil’s infiltration rate.

• Flushing keeps the DL2000 dripline clean.Any particles that accumulate at the endof the submains and driplines will beexpelled from the system. This processcan be automated or done manually.

• Problem detection is not complicated.Leaks can be found easily by walking thesystem and looking for excessively wetareas. Pressures should be checkedroutinely and compared to earlierpressures.

• Clean the filter as often as necessary. Innew installations the filter should bechecked frequently. When using cleanpotable water sources, two cleanings ayear are enough.

Maintenance Tips

DL2000® System Components

StaplesUsed to secure irrigation system wheninstalled above ground.

• Use 1 SS6 staple for every 2’ of DL2000 in sand, every 4’ in loam and every5’ in clay.

• Use 1 SS6 staple over eachfitting adapter and 2 overeach tee and elbow.

Drip Zone Valve KitPlace the kit before each drip zone.

• Kit includes ball valve, Y-filter, control valve, pressure regulator and necessary fittings.

• Available in 3/4” or 1”, low- and medium-flow valves (see part numbers below).

Automatic Line Flushing ValvesProvides for system flushing each time thesystem is started. (Part Numbers FCH-H-FIPT— 3/4” FPT, sealing pressure; FCH-H-FHT —3/4” FHT, sealing pressure)

• Install at furthest point from the water source.• Install in valve box with a gravel bed capable

of absorbing about 1 gallon of water.

Operation IndicatorA visual indicator that pops-up duringeach subsurface irrigation cycle. (Part Number DL-MP9 – Pop-upDL2000 Operation Indicator)

Air/Vacuum Relief ValvesEssential to provide vacuum relief within theirrigation system. (Part Numbers YD-500-34)

• Recommend on all high points of irrigation system to provide vacuum relief at system shutdown

DL2000® Features and Benefits

Precise Water Application

Flowers, shrubs and grass will receive the

precise amount of water required for proper

plant health while at the same time

eliminating water marks on expensive

hardscapes such as walls, glass or signage.

Safer Surroundings

When DL2000 is installed below ground,

the landscape surface is free from irrigation

equipment that may disrupt activities or

cause injury. Over spray and irrigation run-

off are minimized and water is applied

directly to the root zone, therefore slippery

walkways are no longer a liability.

Design Flexibility

DL2000 irrigation systems fit narrow and

odd-shaped landscape perfectly. Irrigate

trees, shrubs, ground cover and turf in

virtually any landscape area. And DL2000

1⁄4" microline tubing is ideal for small,

tight areas.

Advantages of SDI.

• More efficient water usage

• Greater application uniformity

• No run-off or overspray

• Reduced weed growth

• Healthier plants

• Less pest and vandal damage

Advantages of SDI

Environmentally Friendly

Irrigating with Toro DL2000 saves water.

Irrigation takes place at or below grade so

there is minimal water loss due to mist,

evaporation, run-off or wind. In addition,

the amount of chemigation and fertigation

required to maintain the health of your

landscape is decreased since these are applied

directly at the root zone. DL2000 requires

less handling, so it is safer than any other

sub-surface irrigation product on the market.

ROOTGUARD® Technology

About ROOTGUARD Technology

Toro DL2000 dripline features patented, non-toxic

ROOTGUARD® technology, which prevents roots from

clogging irrigation emitters. The pre-emergent, TREFLAN,

is impregnated into the emitter during the molding process

and requires virtually no maintenance. There are no filters

to change and no chemically treated disks to handle,

making it the safest subsurface system in the market.

Once DL2000 dripline is installed in the ground, the slow

release of TREFLAN creates a barrier around the emitter.

Roots are directed away from the emitter opening,

ensuring optimal water application.
