Hi Stephen, thanks for watching and commenting! It's true that you can adjust the slip clutch while the sprinkler is running, but it's not the best adjustment. Much better to do a rough adjustment while the head is off, then fine tune while running.

You're welcome, thanks for watching!

Hi Cobra Venom, there's a couple variables that I don't know, such as your supply pressure and flow. But there is a pinch point that I see. Funny Pipe, or 1/2" poly tubing is rated for 4gpm. You might be able to get 5 maybe 6 gpm if you have real high pressure. So, if your 3 x RB 5000s have the 1.5 gpm nozzle in each of them, you're ok, but if they have larger nozzles, it might be why you're only getting 17' of distance out of the heads. So, first figure out what nozzles are in the sprinklers, or which nozzles you want to use, add them up for total flow of each zone. Then you should check the pressure and flow of your source, to make sure you have enough to begin with (probably 40 or 45 psi pressure minimum, depending.) I would also consider using 3/4" poly which can comfortably flow 8 gpm, or 3/4" Class 200 PVC which can flow up to 10 gpm. OR, if the heads have nozzles larger than 1.5, change them to 1.5s and see if it improves your coverage.

@@Proirrigationtraining aaaahhhh so I am probably restricting my sprinkler heads by already using the 1/2 Poly pipe. The heads did have 3gpm when they were first tried. I stepped all of them to the 2gmp and one of them even to the low angle 2gpm. I will go home and turned them on ans measure distance and then switch to the 1.5 gpm and measure distance one more time to see if that helps. Thanks

@@cobravenum So, did you get better performance with the smaller nozzles?

@@Proirrigationtraining not yet. We got some good rain in the past week that I have not had to water. I might have to water tomorrow if the thunder storms don't come by the time I come home from work.

You've got it correct. You can turn the left limit either direction. Just be gentle with the channel locks your first few times. It's easy to crack the shafts if you grip it too hard.

​@@Proirrigationtrainingdont you run the risk of loosening the head from the water supply by doing this? Creating a leak?

@@cindybriggs8560 Only if you turn them too far on their fittings. Some small adjustments shouldn't cause a problem. There's several turns of threads on the connecting fittings, so they usually don't have to be completely tight. If you needed to make a large adjustment, it may be better to take the sprinkler guts out of the case and drop it back in close to the adjustment you need. This isn't a precise adjustment though, and you usually need to still fine tune it a little.
