GroundWork T-Post Sprinkler is rated 2.7 out of 5 by 40.
Rated 2 out of 5 by from Needs rework I bought 25 units for a irrigation project of a new pasture. I experiences three flaws: 1. The screw holding the switching mechanism gets loose after a short while. It is not properly fastened by the manufacturer. Can easily be solved, after waste of water. 2. On some units the friction to rotate the head is too high. It barely rotates the head even under high water pressure. 3. The clamp force of the angular limiter clamps is too weak on some units. Rather than make the vertical lever to switch to the opposite direction, the lever just pushes the clamp around the neck and therefore extends the swiping angle of the sprinkler. Conclusion: Overall an unusual painful experience with this product from TSC. I also own a few of the bigger model SKU #127075899, which are much much better, not to say flawless. Unfortunately I could not get more of them, they are sold out in stores and not available on mail order.

Rated 2 out of 5 by from Poorly designed I bought to cool off pigs, and water their pasture. Works great in full circle mode, but will not return when on half circle setting.i have setup the older models from 30 years ago, this one has some improvements over those, but will not work as designed. Love the t post mount option and male/female hose connections- if it would return after switching to return mode.

Rated 1 out of 5 by from Don't waste your time or money I bought this 3 days ago. I returned it today. The sprinkler does not work properly. The screw that holds the return action together continues to back out of the threads after about 20 minutes of working. You have to stop the sprinkler, and tighten the screw. If you don't it will not return. It will get stuck and drench the area it gets stuck in. I was going to try a little lock-tite on the screw, but decided to return the sprinkler instead. This is a badly designed sprinkler. I had read other reviews about the same problem, but thought that maybe they had fixed the problem by now. Unfortunately they haven't.

Rated 5 out of 5 by from Good quality sprinkler head I purchased one of these sprinklers a year ago and it was so handy, I've decided to water my whole garden with these: 4 around the perimeter aimed inside the garden and one in the center. No more dragging hoses and sprinklers for me.

Please send the information on how to make it oscillate again. Three days of use and now nothing. There’s a screw?

How many gallons per minute? 

Asked by: Lepager
The flow rate (Gallons per Hour or Gallons per Minute) is dependent upon the source. For example if the source is pushing out 3 Gallons per Minute so will the sprinkler however if the source is only pushing out 2 Gallons per Minute) that is all the sprinkler will be able to push out.
