InstallationA well managed system will improve production, reduce waste and save energy.

Handling and PlacementDrip tape should be handled with care. Growers are advised to follow these guidelines when installing a T-Tape system.

Keep T-Tape reels protected from the environment before use. If possible, store inside.

Do not remove wrapping from reels until ready to install.

T-Tape must be installed with the printed side and outlets facing up. This prevents the settling of sediment in the inlets that could cause plugging.

Subsurface T-Tape irrigation provides additional benefits. T-Tape is commonly buried at depths of 1 to 24 in. (2.5 to 60 cm), and results in the following advantages:

Maintains T-Tape in the proper location so it is not moved by wind or temperature fluctuations. Decreased surface evaporation of water, crop protection materials and fertilizers. Improved uniformity of water, fertilizer and chemical distribution and direct placement in the root zone. Surface area remains drier resulting in reduced disease and weed pressure.

When used under clear plastic mulch, T-Tape must be completely buried to eliminate the possibility of burning the tape. This magnification effect is caused by the sun’s rays being focused by water droplets formed on the under side of the plastic.

The placement of T-Tape depends on the growing technique, the type of crop and soil structure.

T-Tape Layflat InstallationInstall T-Tape Layflat hose in a trench when using as a manifold/feeder. This keeps the hose from moving away from the tape laterals which can stress the fittings or cause the supply tubes to pull out.

The trench for 6 in. (150 mm) layflat should be approximately 6 in. wide by 3 to 4 in. deep (15 cm x 8 cm).

The trench for 4 in. (100 mm) layflat should be approximately 4 in. wide by 2 to 3 in. deep (10 cm x 5 to 8 cm).

The layflat hose must be pulled taught after it has been rolled out. Pull tight every 50 ft (15 m) to eliminate kinks and ‘snaking’.

Installation Options

Installations can be performed manually or mechanically. When designing or shopping for an installation tool, consider the following:

Mechanical Installation Install metal, wooden, or plastic discs against the corrugated reel sides for proper support.

The assembly, consisting of the spindle, reel, and the side plates should turn as a single unit.

The distance between the bottom of the reel and the injection tube entrance should be no less than 28 in. (70 cm) to avoid subjecting T-Tape to sharp angles which could potentially cause damage from excess friction.

When assembling the tape injector, make sure that the injection tube and all other paths are smooth and free from sharp edges and burrs.

The tube opening should be flared to avoid the rubbing of the T-Tape against the edges.

Flatten the outlet of the tube to avoid twisting of the T-Tape.

Manual Installation Avoid friction on rough or sharp edges, nicks and excessive tension.

Allow the T-Tape reel and side disks to turn freely during installation.

Insure that the T-Tape lateral is not dragged on soil that contains rocks or debris from previous crops.

Installation Process

Installation depths range from above ground and shallow (1 - 8 in /2.5 - 20 cm) to deep installation (9 - 24 in / 22 - 60 cm).

T-Tape is injected seam-side up into the bed using specialized equipment. T-Tape delivers inputs directly to the root zone of the plant.

T-Tape Hook-Up and Repair Techniques The lateral hookup is the point of connection of the T-Tape line to the submain. T-Tape Fittings or polyethylene tubing may be used for repairs and to connect T-Tape lines to the submain. Wire ties are frequently used on surface systems to repair and attach laterals to submains. The following photos and drawings demonstrate how to connect T-Tape to the submain and how to repair tape.

Fold the end of the T-Tape twice and secure with asleeve cut from same T-Tape.

System Start UpStarting a drip system is easy if a few guidelines are followed:

If using a media filter, backwash it. New sand in media filters contains fine particles that do not wash out during the manufacturing process. These particles restrict flow and must be flushed out as soon as possible. Usually a 5-7 PSI (0.35 - 0.5 bar) differential across the filter bed is acceptable. A large differential may indicate more backwashing is necessary. Consult the dealer if the differential will not drop below the manufacturers recommendation. If possible, initially backwash the filters manually. This will eliminate any potential problem with the backwash controller and backwash automation equipment. After the initial backwash, the filter pressure should be watched closely as the system fills. Once the system is running, you can set the controller and test it.

A new system should be filled slowly to prevent problems related to trapped air. The mainlines and submains should be open and allowed to flush prior to closing the ends. After the mainlines and submains have been flushed, close them and continue to flush the lateral lines. This will remove dirt and debris that has collected in the lines during installation.

Check the pressure at the pump, filters, mainlines, submains and lateral ends. Be sure to note flowmeter reading. Your findings should compare with the design calculations. This will also confirm the uniformity throughout the system.

Walk the fields and check for leaks. Pressure readings taken earlier will indicate if major leaks are present. Little or no water coming out of a lateral indicates a possible restriction upstream.

System Operation & MaintenanceProper operation and maintenance programs are essential to the continued success of a drip system. Pumps, filters and T-Tape are the key components of the system and they must all function properly.

When the tape is buried, it is necessary to have adequate water application to avoid plant stress. Plant stress could induce root intrusion, resulting in flow restriction.

When applying fertilizers or chemicals through T-Tape, operate the system until all residual material has been flushed out. Where rodents and insects (i.e. Mole crickets, wireworms) are potential problems, insecticides should be used before or during a T-Tape installation.*

Maintain a chemical balance in the water, as chemical precipitants can plug the drip system. Algae and bacteria must also be controlled.*

Acid and chlorine injections are necessary for maintaining the efficiency of the whole network.*

Flush T-Tape laterals regularly.

All pumps should be inspected regularly by a qualified maintenance person.

Filters must be maintained and cleaned regularly during the growing season. Media filters in particular should be cleaned and prepared for off-season shutdown, and the filter sand should be replaced at intervals recommended by the filter manufacturer or your dealer.

T-Tape must be kept clean and free of debris.*
