Drip Irrigation Products Information

We're pleased to be able to offer this and other pages that provide information on plumbing products or the installation and/or care of many of the products offered on our site.

Low volume or micro-irrigation is ideal for virtually all landscaping applications. It is used throughout the world and is suitable for both small residences and large commercial projects. Some typical applications are as follows:

  • Trees and Shrubs
  • Ground Cover
  • Patio & Container Plants
  • Vegetable Gardens
  • Flower Beds
  • Medians & Pathways
  • Island Planters
  • Indoors
  • Hanging Baskets
  • Hedges

Low volume/micro-irrigation may be broken into 4 categories

Drip Emitters
Drip - Drip emitters are the most precise option, delivering water directly to the soil at the root zone at very slow application rates. Drip emitters are suited to shrubs, trees, hanging baskets etc. Because of the low discharge rate, the watering cycle is usually longer.

Drip Bubblers
Bubblers - Bubblers are most often used for shrubs and trees. With their higher discharge rates, they have short watering cycles. Because bubblers can operate at high pressures they are particularly useful for conversion from conventional sprinkler to low volume systems.

Micro Sprays
Micro-Sprays - Micro-Spray is the suggested method of irrigation when low volume overhead irrigation is desired. Ground covers, ice plant etc. are often irrigated with micro-spray emitters. Also plants like ferns, which prefer some humidity, will benefit from this method.

Laser-Drilled Tubing
Laser-Drilled Emitter line - Emitter line is best suited for watering closely spaced plants, hedges, vegetable gardens etc. New plantings of ground cover could also use this emitter line. Other applications include planter boxes and rings for large pots and containers and loops around large trees.

These 4 options can be combined in any application, but keep in mind that each method may have different watering cycles. Hence, it is generally recommended that the different methods be put on separate circuits and operated independently, either manually or through a multi-station timer.

About Drip Irrigation Fittings

1/4" Fittings are used for connecting 1/4" microtube to sprinklers or drippers and then to a 1/2" tubing mainline. These fittings may also be used to connect 1/4" tubing together for watering potted plants.

1/4" fittings have two types of ends "Barbed" and "Compression". The barbed ends are for fitting into 1/4" tubing or 1/2" tubing, while the compression ends are for fitting into hard plastic dripper heads.

Fittings come in configurations of Straight, Tee, Elbow, and in Plugs. Plugs close either the ends of 1/4" tubing or holes in 1/2" tubing.

All of our 1/4" fittings will work with any of our 1/4" tubing or any other tubing with an I.D. (inside diameter) of .155 to .160.

We sell three sizes of connectors that will fit our .700 Drip Irrigation Poly Tubing. The sizes are measured by the outside diameter (O.D.) of the tubing. We carry the following sizes of poly tube connectors.

1) .455 / Color Code = Red
2) .620 / Color Code = Green
3) .710 / Color Code = Blue

The color codes refer to the color of the inserts on the ends of the fittings not for the entire fitting. The body of all the fittings are black.

Fittings that connect to poly tube work by a compression fit. The poly tube goes inside the fitting and is held in place by a sharp edge angled toward the inside of the fitting.
These fittings will hold poly tube with pressure up to 50 PSI but we do not recommend using pressures above 25 to 30 PSI.

We also have many fittings that have one end threaded for connection to a head assembly or hose bib and the other end in compression for connection to poly tubing, and we also carry what are called PVC compression inserts. These inserts are glued into 1/2" PVC slip fittings and make the PVC fitting into a compression fitting for poly tube. They glue in with regular PVC cement. This is very handy when using a PVC mainline along rows of plants.
