We're having our pool built right now (they're doing Tile & Coping as I type this, and are on their 2nd day of stonework - MAN, that's hard work!), and they will soon be doing the decking, which means they will be re-routing my underground sprinkler system soon.

We didn't pay for the PB to attach a sprinkler system zone to the pool's fill line. Right now, the PB is planning to attach the fill line to a spigot, and has actually plumbed the fill line into the gunite. I was wondering if I could do the plumbing to attach the fill line directly to my sprinkler system myself. The folks that did our original sprinkler system used 13-strand sprinkler wire, and two of the strands are currently unused, which should mean I have room for two additional zones (the controller will have to be upgraded as all its zones are in use already.)

My question has to do with the plumbing - do I just have to run PVC from the water supply line to an inline sprinkler valve, then from the valve directly to the pool fill line? Is there anything that needs to go in between? Also, can I connect both the sprinkler supply line as well as the spigot (which the PB is connecting) to the pool fill line? I figure once it's time to fill the pool, this would allow me to get more water into the pool quicker.

Any suggestions welcome!
