Scientific studies state it is 'hog wash'...The Pseudoscience of Water Witching
Sorta like Ouija Board
Honestly I didn't move it....LOL
Well hog was/ Pseudoscience whatever
I was keeping an eye on a neighbors home while they were at Loma Linda Medical for cancer treatments on their daughter
I walked thru the house one afternoon and noticed a wet spot on drywall close to water heater.
By the time I got out to the roadway and located the main shutoff, the line let loose and partially flooded the laundry area.
I cut open the wet drywall and the stub up lines were intact...expected to find a split/bad solder job---nothing
Called out a plumber to have them locate/fix leak
About 1 hr later one plumber showed up. He poked around/had me turn main back on then off...he showed me where the stub outs come up and said water blew out from around them so leak was somewhere under the slab on main line
He called someone to bring out their sonar machine to help locate.
While waiting he got out couple brazing rods...bent them in to 'L' shapes and said "I've had some luck at this before"
Walked back/forth and 'located' direction/run of main line then had me turn on water --let run for 1 minute then shut it back off.
When I got back inside he had marked an 'X' on floor and said 'Think I find the leak' (roughly 4' away from water heater/wall section)
Sonar guy showed up...they did the scan....YEP right there were 'X' is
Cut out section of linoleum, busted out the slab and bingo.....right were the 'X' was the split in main line....rock had rubbed a weak spot in cooper line and it burst under the 80# supply pressure
Did the Dowsing work??
Did plumber have a suspicion where leak was from sound?
Did the sonar guy just agree and went along?
He did mark it in the exact spot
Hummmmmmmm
