I live in a housing addition (built 1965-1980) in the barren (no trees) Oklahoma panhandle. The first thing the new home owners in this area did was plant as many trees as possible.
Over last several years in my neighborhood many of these house sewer lines out to the alley main line are being dug up to replace either rotted (cast iron tree rooted pipe) or collapsed schedule 20 PVC (yes 20 not 40 schedule).
I guess my line is PVC because bent cloths-hangers & rented metal pipe finders won’t even blink to indicate cast iron. So knowing that at any time now it will be my turn to destroy my heavily treed back yard to replace my sewer line.
This town is trying to die & most plumbers have retired or moved off & not one of the remaining plumbers has a camera or pipe line sensor to run down the closet toilet to locate the line out in the yard. Also, there are no clean outs in yard which could indicate where to start digging.
The next time it snows, if I pull the toilet off of the closet flange, configure a 4” to 24” square metal HVAC pipe duct funnel, set a 24” x 24” box fan on top of funnel, turn the central heat up sky high & blow hot house air down funnel into sewer line, would I be able to melt the snow so I can see where the pipe runs?
