HRS-150 Slim Spray Body The traditional, slim-profile 4 pop-up head has been a workhorse of the residential sprinkler world for decades. But it has always lacked the commercial-grade features needed to make it a true thoroughbred. Until now. Hydro-Rain is proud to announce the new HRS 150! An old classic redesigned to be a modern champion. We started with the wiper seal, co-molding it as one piece with the cap and made it with TPR rather than PVC. Next, we built a seal-protecting spring retainer into the head. We also gave the retractor spring plenty of commercial-grade muscle and longevity. Finally, we made sure the HRS 150 was bred with all the other sterling traits that have made Hydro-Rain products frontrunners for over three decades. All that, combined with the traditional slim-profile head design that fits discretely into residential landscapes, makes the HRS 150 a sure winner.
