What is the best pipe to use for sprinkler system?

Polyethylene is the best bet for special situations in areas where sprinkler and irrigation systems require flexibility. Both types of pipe are durable and can withstand many elements in the environments where they excel.

Is it better to use PVC for sprinkler system?

The standard 1″ PVC pipe used for lawn sprinkler systems is rated to withstand 200 PSI. Comparable 1″ Poly pipe is rated to withstand 100 PSI. In fact, to achieve the same pressure rating as PVC, the walls of poly would have to be 2 times thicker. Poly pipe uses squeeze clamps or saddle fittings which are unrated.

How big should a sprinkler supply line be?

Sprinkler supply lines typically are 3/4 to 1 inch in diameter. The depth of the lines needs to be at least equal to the diameter of the pipe plus 4 inches. This will ensure the pipe sits far enough underground to insulate the pipe and make sure that it isn’t easily disturbed by surface activity.

How big of a PVC pipe do I need for a sprinkler system?

That number is flow rate in terms of gallons per minute, or GPM. For schedule 40 PVC, use 1/2-inch pipe for a 4 GPM system, 3/4-inch pipe for 8 GPMs, 1-inch pipe for 13 GPMs, 1 1/4-inch pipe for 22…
