Finding/Locating sewer line under basement floor
I own a property that has a cast iron sewer line that runs under the
basement floor, and I want to be able to mark out and locate where it runs under the basement floor. I know that I could hire a company to come out and do that, but I am wondering if there are any fairly cheap, creative, and interesting/fun ways for me to try to locate the line myself. For example, is there some kind of small signal generator that I could attach to a sewer line snake and detect the signal from above with some type of detector? -- maybe something that Radio Shack or some electronics store might sell? Or, are there relatively inexpensive underground pipe-locating devices that I could rent somewhere and do the job? Would a metal detector be able to detect a cast iron pipe under a concrete floor (assuming that the pipe is not down very far below the floor? |

Finding/Locating sewer line under basement floor
You could buy about 50 pounds of radioactive waste from Japan (on ebay) and
put that in the drain. Use a geiger counter to follow the signal. That's creative, fun, and memorable. Toner tracer set like the phone guys use. On sale, at HF. http://www.harborfreight.com/cable-tracker-94181.html Have your mother in law yell into the toilet, and pretend to trace the line. Keep saying "A little louder, dear" DAGS: http://tinyurl.com/83atd7u I'll think on this for a while, and some other zany ideas will come to mind. Christopher A.

Underground pipe/conduit/wire tracers can be rented from places like United Rentals. They couple a signal from a transmitter onto the exposed part of the line in question, normally with an inductive clamp connection, and a separate handheld metal detector style receiver is used to sweep the ground to locate the line. You sweep back and forth over the line to find the peak signal which should be directly above the line. If there is rebar / mesh in the slab if could make it more difficult to pinpoint the line under it. |

You might try an electronic stud finder at the sensitive setting, it depends on how deep the pipe is buried under the concrete. Worth trying. |

Dowsers are as full of **** as a Christmas goose. If you know someone that can successfully dowse, tell them they can make a quick million at: http://www.randi.org/library/dowsing/ Don't know about 'dowser', but my father used to use those L shaped thingies to find buried wires/cables/pipes BEFORE he would start any construction. He could never count on the company's/county's records. During mid school age after finding them hanging in our garage and receiving a demonstration of how to use them from my father, I used the L thingies to map everything I could find in our back yard. I found all the pipes, even the underground stream that fed our well. Just a child's project resulting in a map drawn to scale, Father very impressed. Explanation for why the L thingies work? Don't know, don't care. They work. The wires definitely 'feel' like they're tugging at each other when they cross. Possibly, and I am coming to more believe this, a human being has more capabilities than thought, and distracting the mind with weird items 'releases' those abilities, removes distractions, disbelief, if you will. Always keep in mind that science DESCRIBES our observations. Science does not DEFINE our observations. |

He also ran a snake down a clearout and measured how much was being fed as well as detecting any noise. I suspect you can use a stethoscope instead of a piece of wood. Good Luck. |

I'll have to try the stethoscope idea. I can't picture it actually working too well, but I happen to have a stethoscope, so I'll try it and post back how well it worked out. |

Go down to your local tool hire shop. If it's not too deep, a metal detector. The pipe locator guys inject a signal on the pipe and detect it from above. I built a crude one. used a function generator at 6.5kHz to inject a signal between the pipe and ground. That just happened to be the peak sensitivity of the receiver. Sensed it with a coil wound on a vertical ferrite stick. Plugged that into the microphone input of a computer. Used a sound card scope to detect it. I used a pda and a spectrum analysis program, but any old computer should work. |

Prove it or fut the shuck up! http://web.randi.org/the-million-dollar-challenge.html I believe it works by detecting the magnetic field of the thing you're looking for. There is a phone line from my house to the shop and dowsing will find it easily. There is also an electrical line from the shop to the sauna and that is also easy to detect. Dowsing for a water source is unpredictable in my opinion. Those that claim success I think are paying educated attention to the geology of the area in question. The reason I believe it to be a magnetic thing is because I use a 1/16 steel TIG rod. Alum brass or SSTL doesn't have the same action. |

Finding/Locating sewer line under basement floor

stuff snipped I believe it works by detecting the magnetic field of the thing you're looking for. There is a phone line from my house to the shop and dowsing will find it easily. There is also an electrical line from the shop to the sauna and that is also easy to detect. Could it be that they are easy to detect because you already know that they are there? Every test of "cold dowsing" where the dowser has no idea of what they are looking for ends pretty poorly. Dowsing is considered to be a pseudoscience. A 1948 study tested 58 dowsers' ability to detect water. None of them was more reliable than chance. A 1979 review examined many controlled studies of dowsing for water, and found that none of them showed better than chance results. A 2006 study of grave dowsing in Iowa reviewed 14 published studies and determined that none of them correctly predicted the location of human burials, and simple scientific experiments demonstrated that the fundamental principles commonly used to explain grave dowsing were incorrect. A randomized double-blind trial in 2012 was carried out to determine whether homeopaths were able to distinguish between Bryonia and placebo by use of a dowsing method. The results were negative. James Randi offered a US$10,000 prize to any successful dowser. The three-day test of some 30 dowsers involved plastic pipes through which water flow could be controlled and directed. The pipes were buried 50 centimeters (19.7 in) under a level field, the position of each marked on the surface with a colored strip. The dowsers had to tell whether water was running through each pipe. All the dowsers signed a statement agreeing this was a fair test of their abilities and that they expected a 100 percent success rate. However, the results were no better than chance, thus no one was awarded the prize. A 1986 article in Nature included dowsing in a list of "effects which until recently were claimed to be paranormal but which can now be explained from within orthodox science."Specifically, dowsing could be explained in terms of sensory cues, expectancy effects and probability. Skeptics and some supporters believe that dowsing apparatus has no power of its own but merely amplifies slight movements of the hands caused by a phenomenon known as the ideomotor effect: people's subconscious minds may influence their bodies without their consciously deciding to take action. This would make the dowsing rods a conduit for the diviner's subconscious knowledge or perception; but also susceptible to confirmation bias. (This last paragraph explains what I said about knowing where the object was already. It's easy to find a wire or pipe that you have a fairly good reason to believe is already there - like a connection to an outbuilding.) Source https://en.wikipedia.org/wiki/Dowsing -- Bobby G. |

They can find a pipe, open it, and even crawl through it to be sure no clogs. If it's green it may not be a pickle... -- Tekkie *Please post a follow-up* |
