What fittings does a drip irrigation system need?
A drip irrigation layout typically needs five fitting types: a grommet or take-off connector (joins the lateral drip line to the main pipe), an end cap (seals the far end of each line), an elbow and tee (for direction changes and branching), a joiner (repairs or extends a line), and a valve (controls flow to each zone). Missing any one of these is the most common reason a drip system underperforms.
How do you choose fittings for a small farm versus a large one?
For plots under an acre, 12mm and 16mm lateral fittings with manual grommet take-offs are usually enough. Larger plots benefit from 20mm or 25mm sub-main fittings with control valves at each zone, so water can be directed to one section at a time instead of running the whole field together. Kasta's drip irrigation range covers both scales within the same product line.
Why do drip fittings fail faster than pipe fittings elsewhere on a farm?
Drip fittings sit exposed to sun, soil movement and frequent manual handling during the season, which ages the plastic faster than buried or indoor pipework. Fittings made from UV-stabilised material last considerably longer under these conditions, which is why the material grade matters as much as the size.
What is the difference between inline and online drip fittings?
Inline drippers are built into the pipe at fixed intervals during manufacturing, so spacing is uniform and there is nothing extra to fit. Online drippers are punched into the pipe wherever needed, which gives more flexibility for irregular plant spacing but takes longer to install. Kasta supplies both inline and online drip pipe options, so the choice comes down to how uniform the plant spacing is.
Do drip fittings need a filter before them?
Yes. A screen or disc filter placed before the first take-off prevents grit and organic matter from blocking the small openings inside drippers, which is the single most common cause of drip system failure in the field.
