I just moved into a house with a sprinkler system. The central controller is a Hunter Pro-C, and there are a variety of zone and types of sprinkler heads. In the front bed by the curb is a drip line, and today I dug it up b/c it didn't seem to be working. I found the problem--one line with several drip heads or emitters had been disconnected from the main line.

The problem is I can not figure out how to reattach the mini line to the main line. It doesn't seem to fit into the hole it should fit into. For that matter, I can't even firgure out how to remove any of the clogged drip heads either. They don't seem to easily detach from the main line. The brand name on most of the drip heads is Rainbird, but after a quick seach on the web, I can't seem to find that model or any advice on how to disconnect and reconnect (at the connection point, the heads are inserted into mini-line, but in a way where they can't be unscrewed or pulled out.

Any advice? Either on how to work with this product or where to find the info I need?

Thanks a lot,

Jenny
