When it comes to selecting the right pipe for your lawn sprinkler system, there are a few factors to consider.
Polyethyleneis the ideal choice for environments that require flexible tubing, such as rocky soils or cold climates where the ground is likely to freeze. This type of tube is increasingly being used in domestic sprinkler systems due to its high nominal pressures. Other types of pipes available include CPVC, PVC, galvanized iron and polyethylene. The two types of pipes most commonly used in irrigation systems are white PVC (polyvinyl chloride) and black roll-up tubes (polyethylene).
Polyethylene pipes and PEX pipes are also excellent materials for irrigation sides, as their flexibility makes them ideal for use on rocky soils or next to a large rock. They also work well in cold climates, as they do not require any additional insulation against the cold. When selecting a pipe for your system, it's important to choose one with a PSI rating of 20 to 40 higher than static pressure. If the system is subject to heavy use, it's a good idea to use an even higher PSI rating to ensure that no breakages occur. Generally, schedule 40 should be used for the main line from the water meter through the counterflow and to the valves, while class 200 should be used for the sides or after the valves. In addition, a swivel tube should be installed between the PVC pipe and the sprayer to allow for some flexibility in case the sprayer is crushed or hit.
This allows the installer to move the sprinkler slightly during installation if needed. At BG Outdoor Services, we've been designing, installing, repairing and repairing lawn irrigation systems since 1988. As an expert in lawn irrigation systems, I can confidently say that the type of piping used in your sprinkler system will go a long way in determining its life. When selecting a pipe for your system, make sure you choose one that meets your needs and can withstand any potential damage. Polyethylene pipes are an excellent choice due to their flexibility and durability, making them ideal for use in rocky soils or cold climates.
Additionally, it's important to select a pipe with a PSI rating that is 20-40 higher than static pressure to ensure that no breakages occur.
