Hunter I-20 - Head wont popup


I have searched the forums on this issues but there is no clear answer.

The Hunter I-20 head doesn't popup on one of my sprinklers. It rotates and works if I pull it up manually. Its about 6 years old.

I tried reading about it on Hunters manuals but I didn't see what might be the problem. First I thought it might be the spring but then I read that the spring is for return not popup..( correct me if I am wrong )... At this time I am not sure what might be the problem.

Any ideas what may be wrong ... and if it would be best to just replace the head ?

Thanks in advance.

Ill bet you have snad keeping it from popping up. dig around the head half way to the bottom. Unscrew the head from the body. I am not talking about unscrewing the head from the supply line. Unscrew the top and pull the head out. Youll now see the spring you were referring to. go to your nearset water source and push the head up and down while under the water and youll clear the debris from the seal. Next put you sprinkler back and turn it on. VIOLA it sould be fixed.

My description may sound cmplicated but rest assured this is super simple. one star out of five.

It may not be getting enough water to pop up...due to an obstruction in the pipe leading to it...

Your suggestion worked great.

The sprinkler head working is great .. i.e. popping out and retracting perfectly. There was some sand and now that its clean its working fine.

Thanks for your suggestion... but my other sprinklers close to the one with problems, are working.

Thanks to both of you for your suggestions.
