Hi all,

I don't actually have a problem currently, but I am trying to locate the
drain for my downspout with no luck. Downspout was disconnected from
drain pipe and diverted to a cistern before I bought the house, however
the overflow drains for the cistern simply dump onto the ground.
There's a stub of PVC pipe sticking up from the ground but it doesn't
let water flow. Well, it does, but very, very slowly. The only
possible location that I could see for it to terminate is that there is
a drain pipe by the curb in front of the house, however it is bone dry.
Trying to stick a snake up that drain from the curb accomplishes
nothing, it is open for as long as the longest snake I have. Trying to
snake it from the downspout end accomplishes nothing either, I get
caught at an S-curve almost immediately.

I will get a longer snake, but I have two concerns... first, I don't
know whether I have a French drain or not, so the drain pipe by the curb
might be for the French drain and has nothing to do with the downspout.
Also I know that when the house was built there was an alley behind
it, and the alley is no longer there.

So here's the question; is there any way to determine where exactly a
PVC drain pipe runs if you can't snake it without digging? Digging this
up would likely involve draining the cistern, moving it, and removing a
large concrete pad.

thanks,

nate

A downspout drain? Damn, never heard of one. I guess I need to get out
more, or maybe I just live in a different part of the country.

Guess so...

For OP, to me this falls into the category of "if it ain't broke, don't
fix it"...

From the description it sounds as though in all likelihood the cistern
is of ample capacity and my guess would be that it has outlets to a
french drain as well as the overflows (or you're in an area that doesn't
get a lot of rainfall) and the vertical pipe is simply an air vent.

Well see, that's the thing. The cistern is just an above ground 550
gallon tank, and it fills up after only a couple good rains. I'd like
to pipe the cistern overflows into a proper drain so that if I don't
manually drain it often enough that it won't just dump water on the
ground behind the house.

I've gotten the pipe sticking out of the ground clear enough that it
will take the full flow from a regular garden hose without overflowing.
But the pipe at the curb is still bone dry so I suspect that they
don't have anything to do with each other.

Is it possible that the downspout was originally piped directly into the
regular sewer? That's the only thing I can think of that makes sense;
either that or I just waterlogged my French drain. I can't hear the
water going into the drain from inside the house, for what that's worth...

Anything is possible; and if it were (in the sanitation sewage system),
that would be a likely reason it was later cut off and something else done.

What is done w/ the cistern water between rains? If it isn't being used
for irrigation or other purposes, might as well just put a diverter on
the downspout(s) and lead them away from the house where the water than
doesn't fall on the roof goes -- there's far more of it than what comes
off the roof, anyway.

If using the cistern water, then if it fills w/o the gutters overflowing
you have plenty of flow path and once it's full after a rain, same
thing--the rest is just excess.

{Sorry long post.}

Smitty-Two:
I am sure you have heard about this. I am now living in my third house
where as part of the local municipal property transfer process, there must
be an inspection of the down-spouts not being tied into either the sewer
system, nor the street storm drain system by way of a downspout drain;
direct tie-in, nor drain pipe to street curb. The inspector dumps a
powerful dye in the roof gutter, and sprays water or some such while some
one else watches the water color at a manhole cover or street. Seller of
house must make repairs before sale of home can go through. As far as I
know, this requirement was mandated at a higher government level.

When I lived near Pittsburgh, PA, heavy rains, combined with slope of land,
and downspout runoff could erode a good hunk of yard down the hill to your
neighbor. The home I purchased there had to have a backhoe dig a 6'X6'X6'
deep hole, filled with gravel and covered with 2' of soil. Size and
location of 'dry well' ended up on county land plot document given to new
buyer when house was sold again.

I don't know all the details, but rain surge water in sewage system can
overwhelm a sewage process plant thus forcing raw sewage into water ways.
Plus storm drain systems are more often now required to filter out yard and
leaf debris as best they can before discharging rain water into water ways.
Downspout adds to amount of water to be filtered. Where I live now, the
debris filtering is designed to overflow (raw discharge leaf debris) only
during real heavy rains.

As far as the O.P. of this thread goes, what I as sure of is that his
neighbors will have almost the same problem of rain runoff potential
problem. What is the solution the neighbors have, and also, what does the
municipal building inspector have to say. The O.P. could be correct, the
size of the cistern is too small, but a larger cistern would be more of a
mosquito egg laying and breading pit than helpful for rain run-off.

I did hear on one of the Home-repair PBS shows that downspout rain water was
collected in one region of USA so the garden water was not added to water
bill (very high water and sewage rates,) not for rain runoff reasons.

Thanks for the explanation. Guess I never lived where all the dirt was
paved over. Gutters direct roof water to a location where it won't fall
on your head or erode your planter beds. The downspout keeps the water
from digging a hole, and points it away from the foundation. The dirt
soaks it up, along with all the rain that *didn't* happen to fall on the
roof. All these french drains and neighbors fighting over the slope of
the land seem like good examples of how silly it is to build homes six
feet apart, and/or in swamp land.

Hi,
If your house/yard does not have water problem(soggy yard, moisture on
the walls, etc.), what's the worry?

I guess it's just the principle... I don't *want* to have a water
problem in the future; the cistern is only a couple feet from the
basement walls.

If you can get a stiff wire or a smaller metal snake (like an
electrician's snake (steel, not fiberglass)) down the pipe, you can
rent a cable/pipe locator.

You clip a connection from the locator onto the snake and that drives
it with a signal. Then the locator head senses that signal to locate
the path of the wire. The better units will even estimate how deep
the line is.

A well stocked rental yard will have one of these. They're usually
called magnetic cable locators. It takes some fussing around, but
they work.

Another idea is smoke testing. You can purchase smoke pellets from
Lab Safety Supply. Toss one in, and if you need to, blow some air to
push the smoke around. Might try a shop vac or a hair dryer or an air
compressor turned way down.
