SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

As the subject says, my front lawn slopes downward quite a bit. I dont have the exact angle, but it can easily be a foot to 2 change in elevation. I've notived that some of the heads at the very bottom, leak out when the watering is done, and I read in another thread somewhere that sprinkler heads exist that can prevent this leaking; they have a check valve that precents the flow of water back out, and it also alleviates the issue of water spurting out of the heads before it. Sure, the installer of the system should have put these, but they didn't, and I'm fighting that battle now.



I attach a picture of my sprinkler layout, with the light green/gray signifying the front lawn. My system has 2 zones: 1 zone with the large rotary heads (In orange), and a second zone with the spray heads in green. After reading that thread, I figure that I can replace the 2 rotors in the front with check valve ones, and some of the end spray heads towards the front. Am I right?



Thanks

Thank you
Which should I replace in my drawing?

thank you and happy NY
Water cost is of no concern, since I am using well water. However, I dont want to waste it either, and I hate the large puddles that accumulate on the sidewalk.

The irrigation company installed Toro brand for everything. Any preference? Pricewise, they are all relatively close, so not a big issue; I only need to buy 3 at most, so this doesnt involve a big expenditure.

I see that mrfixit pasted 2 links for Hunter and Rainbird. I would prefer (if i had a choice) to stay with Toro since each brand appears to have specific threading of the nozzles (female vs male), etc.

What model of Toro rotors?

CENTRAL----thanks again. I correct-----I have Rainbird 5000 rotors. I was looking at the T5 series on the SW site for 2 reasons. The technician from the irrigation company came to look at my leaking rotor, and told me that the puddles come from the water stream hitting the tall grass blades. He might be partially right, but I think he is full of it. The T5 extends 5 inches and comes with a optional check valve; however, I dont see the valve on the SW site, so I may have to call. With the T5, I could avoid the so called tall grass, and I gain an inch which will help me overcome the downward slopping angle of the grass blades. My main goal is to avoid the huge puddles that form from water flowing out of that one rotor.

Brand-wise, I really dont care. I simply have a bucket full of male threaded Toro spare nozzle heads, and I wanted to stay consistent. However, this is only 1 rotor I am replacing so spare parts is not an issue.

The SW site does not sell the Toro T5 with the check valve, so I will look at other brands---the ones suggested by mrfixit.

thank you
