I think the most common use for this small tubing is for drip irrigation systems. The tubing is very small at about 1/4″ in outer diameter and usually comes in lengths of 100 or 500 feet. The roll pictured here is 500 feet. This is another form of poly-pipe and is very flexible and sturdy. I use it as a feeder line to go from my 1/2″ drip irrigation main line out to each plant that I want to water.
There are seemingly numerous different fittings for spraying, misting, bubbling or dripping that will fit onto the end of this micro tube to water different types of plants, shrubs, grasses and trees.
Be careful when buying the micro tube as it is easy to grab line that has emmitter holes drilled every foot or so. This is good if that is what you are looking for, and it works like a soaker hose, but not cool if you want a line that is not going to leak all over the place!
1/4″ poly micro tubing available in lenth of 100′ to 500′. the micro tube is made of the highest quality polyethylene resins and is UV resistant. The micro tube can be used as a feeder line from a 1/2″ poly tube to extend your drippers or micro sprinklers and for a complete 1/4″ system. Use with 1/4″ barbed fittings.
- Operating pressure: up to 50 PSI
- Maximum flow rate: 30GPH

PVC (poly vinyl chloride) pipe is commonly used for residential irrigation systems in the more southern states of the US where the climate is generally warmer. In the northern states where the ground freezes solid and moves, this pipe would crack and break. In the northern colder states, a flexible poly pipe would be more appropriate.
Commonly a schedule 40 PVC pipe is used, is white in color and usually comes in 20 or 40 foot lengths. Usually I would use the 1″ diameter pipe, but occasionally the 3/4″ PVC pipe might be more appropriate for your spinkler system, depending on the flow and pressure you have or need.
When using any threaded pieces to connect the PVC pipe, always be sure to use teflon tape, and when connecting any fittings such as elbows and couplers be sure to use the appropriate glue and primer to avoid leaks.

Poly pipe, or polyethelene pipe is a flexible, usually black pipe that is used for underground spinkler line. It’s more popular in the northern areas of the country due to the cold climate.
The poly pipe is more flexible and allows for movement when the ground freezes in the winter months. Regular PVC pipe, even when the system has been blown out, would crack and end up with a lot of leaks in the spring.
Poly pipe is allows also allows for installation without trenching using a pipe puller instead of having to dig trenches in your yard.
Most commonly I use a one inch diameter line with 125 psi, but I might use a slightly smaller line depending on the amount of water flow needed and the pressure available.

Funny Pipe - One of the great inventions for lawn sprinkler installation from Toro. Funny Pipe adds a lot of ease to installing sprinkler heads for three reasons:
- It’s flexible. You can bend it around corners, under fences, and up to the bottom of your sprinkler head.
- No Glue.
- No Clamps.
Once the Funny Pipe is fitted onto one the the Funny Pipe fittings, it doesn’t come off. It’s made of a tough enough poly material that the barbs hold it on to the fittings, and suprisingly it’s not difficult to push on to the fitting as you would expect with something that holds that tight. There are 7 different types of Funny Pipe fittings (these fittings are special for Funny Pipe, others will not work). They have 3 sized of mail elbow adapters for different size threads for sprinkler heads, a Funny Pipe tee, coupling and then a straigt mail adapter.
Funny Pipe is a must have for any sprinkler job in my opinion. When I make my first trip (usually of many to come) to the store to buy parts when I start a job, a 50 ft roll of Funny Pipe and some adapters are always on my list.
