My sweeper jet has a cap that can be put on while not in use. But, all of my jets are at the same level, so I don't cap it. I have seen the caps in pool stores, & maybe on line. Try www.intheswim.com They may have them too. Atleast you can see what they look like.

Hope this helps..

P.S.) I am a "redneck" also, & ALWAYS looking for cheap fixes....
