1. My sprinkler turret seems to keep turning no stop at all... either way I turn it (left or right) just keeps turning in full circles either direction.... did I accidentally pop something with the adjust tool?
2. Thank you!
3. I stepped on top my spray and broke a piece from bottom hole. How can i get a new spray or even put back the one i broke back into place?
4. I have a zone with 7 - MP 3000 sprinklers. I've suddenly got 3 that pop up but will not rotate. Filters are clean and the other 4 work fine. What should I do now? If this is a flow problem and before I try to reduce the size on all sprinklers, would removing the filters help increase the flow? And if I turn off 2 or 3 sprinklers, I should probably turn off those that are operating normal and see whether it makes a difference in those that don't? Is there an internal mechanism that sometimes fails to rotate the sprinkler? Do parts wear out?
5. My sprinklers don't all rise and when pulled up have a tendency not to retract when no longer engaged. Can they be lubricated?
6. So easy even a monkey could do it.
7. accurate, to the point, w/o wasted verbiage. Many thanks
8. How can I make my sprinkler heads come up without the water being on? This is the only way I can work on them.
9. I have a ton of problems with my Toro 570's either sticking in the down position or the ratchet system will move and I end up watering a wall or the street. Even after adjusting in the correct position the ratchet will move over the next few watering cycles. I have had to replace many of my Toro's even after cleaning them. After 2 years this is when I see the problems I talked about. There are a large number of 570's both in my front and back yard. Each sprinkler is in the proper level position and they were not installed at an angle. I am at the point where I might change to a different brand other than Toro.
10. Will your check valve work on rain bird heads?
11. Dirty filters was constricting water flow through my sprinkler heads. With the help of this video I was able to correct this problem. Thank you for your helpful recommendations.
12. Finally got around to fixing.. Dirty filters :) 
13. When I got my PRO-10A i was expecting the top to be black but its red, and when its in the ground its like a flag. and your filters look diffrent in the video
14. I'm gonna try these tips! One of my spray heads isn't throwing enough pressure... Thx! I need a gray cap thing tho for trouble shooting, or it just might be dirty filter.
15. Muchas gracias, tendrán videos en español?
16. You are a freakin' GOD and THANK YOU! I have searched & searched your website & the internet trying to figure out why after installing my sprinkler and getting the arc set, it would then spray in the wrong direction... Didn't know there was a correct way for it to face and turning the riser was possible or an option! Thank you again!
17. Do your check valves work on all your spray body's and sizes
18. This was very helpful, thank you.
