Super Duper Sprinkler

Super reliable popup sprinkler. The metal top is perfect for my driveway which gets lots of traffic. All the other sprinklers broke but these ones are perfect. You can also adjust the spray radius with the nozzle that is included. Highly recommend!


Flushing Cap: When an irrigation system is built, it often has a build up of dirt & debris in the system, before it is turned on. The PRO-S is equipped with a flushing cap (blue) which allows the system to be turned on & purged, cleaning out any dirt & debris. The flushing cap also allows a system to be tested first, before any nozzles are fitted. The PRO-S riser stem features an industry standard male thread, this accepts ALL brands of female threaded nozzles.

Microbe Resistant Seal: Soils contain many types of microbes. Over time, these microbes eat away & deteriorate rubber seals, causing leaking & broken sprinklers. The PRO-S range of pop up sprinklers have a “Microbe Resistant Seal”. The polymer used to make the seal prevent the microbes from attacking the seal, increasing the life span of the sprinkler by making this seal last longer! K-Rain provides a factory-supported warranty for up to 5 years.

Ratcheting Riser: The ratcheting riser in the PRO-S is a great feature! It allows the spray pattern to be easily adjusted into position. The ratchet at the base of the riser stem allows you to “re-orientate” the spray pattern to cover the correct area in the garden or lawn, once the nozzle has been fitted.

Heavy Duty Retraction Spring: Using a high quality spring, the PRO-S is guaranteed to retract fully every time! This protects your nozzle and prevents any damage to the sprinkler itself, keeping your system fully operational and reliable.
