We have an upstairs bathroom complete with shower, toilet and basin. I'm
trying to find where the drain(s) goes, i.e. where does it run inside the
wall on the ground floor. I've tried running the basin to see if I can hear
anything but no luck. Any suggestions.
Thanks in advance,
If the house is older, or if you know that the drains are metallic,
use a cheapo metal detector. Even a toy will work.
Takes a bit of practice as you may pick up heating ducts, other pipes,
or even foil-backed wallpaper.
You might try taking the trap off of the basin and run a steel plumber's or
electrician's tape down the drain line. If you can get it around the corner
where it dumps into the toilet drain you can flop it around inside the pipe
and should be able to hear it in the wall.
If it is really important you could hire a plumber to use a locator if it is
cast iron he would just hook a sender lead to the pipe and would have no
problem locating it in the wall. If it is plastic he would run a tape down
it and then do the same thing.
Not necessarily all that much help. Perhaps because a) I have a hip
roof, or b) the guys who built my house were idiots, my vent stacks
snake way off of vertical. In this instance it is likely the former in
order to get enough vertical rise, however there is ample evidence
elsewhere to support the latter.
get a portable radio turn it on place it over the
stack on the roof go inside your house take a vacuum
cleaner hose or a paper towel tube and place it on
the wall until you find the loudest commercials about
stuff you don't need or want.
if you don't want to go on the roof you could do the
reverse and put the radio in the sink but you will first
have to clear the water out of the trap so the sound
will get through place a bath towel over the radio in
the sink <don't turn the faucet on cause you'll do
the radio & you a disservice>
if you have a spare person for the find the pipe project
have them tap on the pipe while you try the tube to
the wall trick
