Any hints for finding shorted valves?

    Bcg......trace the common and flag it. Put the black clip on the zone wire and the red clip on the common. You should pick up a strong signal right after you pass the valve. Go back a little listen intently and it should be there.

    RB Seem to be the worst to find when shorted. I dont have any special tricks.

    On a side note I used the TDR for the first couple of times this week after having Jim explain them in detail to me and the tool is unbelievable. I had shelved the unit before talking to Jim due to my misunderstanding of how the TDR operates.

    It told me within 5 foot where the problem was on a 1100' signal wire. I didnt believe the reading until I found it. Top that off the problem ended up being on the common (TDR found it the same).

    Same day TDR told me within a few feet where a valve was 950' from a controller on a different site. Saved me a lot of time on both jobs. Even with the 521 I would have had to do a ton more walking. I had fun with my guys when I told them "Its that valve right there I bet you 20 bucks"

    This is a awesome tool that we all need to learn about and bounce off each other.

    The TDR could tell you within a few feet of where the valve is in this situation.

    Special thanks to Jim for all the info/help he's given us. I'm looking forward to meeting him next week for a locating seminar.

    I very much appreciated our discussion and wish the seminar was a tad closer so I could make it.
    No doubt Jim is an asset to the members of this board.

    Thanks again for the help Jim!

    me too!

    I got the 12th off. My boss wanted to come too but he's on vacation this coming week with the family


    As far as the post goes..
    My first attempt would be/

    I would spray paint / flag the wire trace. Then follow step 2 of the locator by hooking the red power connector to common and the black ground to the missing zone wire ( make sure the controller is off) .. You can't really trace the wire this way but it will sure as hell ping out a bad valve.

    you're welome, happy to be involved.

    i'm getting pretty good at over the phone locates, i don't think it took more than 15 minutes of total phone time to find that valve.
