pipe locating idea
within the next couple days i'm going to try a new idea out.
in the west were familiar with portable electric fences for livestock. the wire is actualy some sort of poly string woven with fine wires.
makes sense that if detectable it would reduce the possibility of cutting the inside corners of pipe. it may be a little more flexible than the coated
aircraft wire i use now.
it's been a slow year so i've put the time i've had to refineing my crafts........both the leaks and the irrigation work.

well friends i tested the locating idea today and would like to share the results with you.
keep in mind this was a locate for a pipe three feet deep and was an irrigation mainline with numerous bends similar to an average swimming pool.
the poly wire is readily available and inexpensive, easily transfers through pipes without drag or damage to pipe.
the wire was extremely conductive and responsive to my tr-4110 peak locator. the gain button sat at 2 for 80 with perfect pinpoint locate, beyond 120
the gain had to be cranked to the max and beyond that the pinpoint grew to +/- 15" ea.way.
this is totally acceptible for pipe locations in the pool leak detection industry.
with this kind of conductor a suction pipe can be located very quickly by introducing the conductor through the skimmer.
the input for the return lines will be depending on the situations you encounter, i myself like to go from the last penetration to the filter on no
loop return lines.
the best part is that the poly is strong and easy to work with, the worst part is that my other locators did not like the poly as well as the 4110.
the dynatel would not tell depth. peak, null, depth and directional were o.k. for a pool job but not to pinpoint accuracy.
i also used my 521 and pro 600 valve locators and they were sketchy to be honest.
if any one is interested a source for poly wire is www.horse.com/electric-fence-wire.
the tr-4110 is out of production but availible on ebay.
i'm at a point right now that i locate pipes before i pull out the xlt.
thanks for your time, i hope this may help at least 1 person in the biz

Great tip about the wire. I have a pipe/cable locator that will put signal on anything metalic and was wondering what could be put through the pipes.

Good post. I am with you . If its a major system I am locating pipes first before the xlt 30 comes out .on residential pools i have not used pipe
location that much because its a small area that I have to survey to find a leak. in larger systems pipe location is mandatory. I will try that site
and that particular product. iam sure it will work fine.

How do you get the polywire into the piping system ?

normaly i introduce suction through he skimmer, having a assistant turn the pump on and off or pre measure enough line and tie it off and run the pump
switch myself
returns are introduced from the filter to the farthest return penetration, i build a 90 degree riser for the return and plug the other return openings
and use a shop vac to remove water and pull the string through
1 thing i have to say is that the first few times it may seem like yuo're wasteing time but before long you'll become more familiar with what fits
your needs and the time you're saving.
adriaan, the e-mail address would not work for me
good luck
jim

tell me how well it worked? i've had mixed but good results overall. the hardest part is getting a good connection with the wire, last time i used 2
pieces of metal and some vice grips to get contact.
