Drip Line Lengths

When branching out from the main pipe with your drip tubing, be conscious of each dripline’s length. Simply put, a drip line can be too long. As water moves down the tubing, pressure begins to drop, so the far end may water less evenly than the beginning. Many 1/2-inch driplines start to suffer after 100 ft., but some specialized products with wider emitter spacing can run much longer. To accommodate longer drip areas, avoid using one very long dead-end line. Instead, split the area into multiple shorter laterals. 

Irritrol Drip Irrigation FAQs

How deep should drip irrigation tubing be buried?

Drip irrigation tubing is usually installed on the soil surface or buried a few inches deep. Drip tubing is generally not rated for deep burial, as the tubing could otherwise become contorted from the surrounding weight. In most outdoor setups, shallow burial helps protect tubing from sun damage and yard tools while still making repairs relatively easy.

Can I connect Irritrol drip tubing to PVC pipe?

Irritrol drip tubing can be connected to PVC pipe with the right adapter. A common setup is PVC pipe feeding a drip zone through a filter and a drip tubing adapter that matches the tubing size. Don't forget to include a pressure regulator if necessary. Standard home water pressure out of a PVC line is usually too high for drip systems, which are only designed to handle 25 to 30 PSI.

What fittings work with Irritrol drip tubing?

Irritrol’s drip tubing typically works with standard drip irrigation fittings that match the tubing size. A few of the most common options include compression fittings, barbed fittings, couplings, elbows, tees, end caps, flush valves, and threaded adapters.
