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

I have a sprinkler system that works fine. Trouble is I have now installed an emergency power system and one of the sprinkler heads is located close to the power system. I would like to permanently disable that one sprinkler. I tried to purchase a simple cap for the pop-up tube, but could not find one.

(a) What is the best way to accomplish my objective?

(b) If the answer is replace the nozzle with a cap, where can I get one? I believe the pop-up is a Rain Bird, approximately 1/2 inch OD.

Many thanks in advance for any help.

I have been to hardware stores, Home Depot and Lowes without finding the cap. I bought what I thought would do the job, a 1/2 pvc cap, but it was too large. I can find replacement sprinkler heads of various kinds, but nothing that will simply plug the riser and stop the flow of water.

I now have two solutions that work.

1. Easy one that nobody mentioned: install a sprinkler head on top of the riser, and turn the adjustment screw fully clockwise. This effectively shuts the sprinkler head off. No cost involved.

2. Dig up the space around the riser and remove the riser. THEN the caps that responders were telling me to get will work. Those "caps" will not install on top of the riser. Not knowing what I was doing, I was asking for a cap that would accomplish method 1 above. Not available.

I ended up getting my installation contractor out to cure some other problems I was having, and he told me how to do the above. I did solution 1 and it did work, but since he was there anyway, he did the more professional job, solution 2, for me.[]

Thanks for all the responses. This one is now ready for the archive.
