Builder used perforated pipe for gutter downspout drain, is this okay?
|
|

| House about 1 year old, new construction. Gutter downspouts are connected
to the usual black 4" corrugated plastic pipe, and the pipe is wrapped with
weed mesh, BUT they used the perforated type instead of the non-perforated.
Shouldn't this be the non-perforated type so as to prevent the water from
leeching into the ground as it moves through the pipe on the way out?
Just checking to see if use of perforated pipe is common and acceptable for
piping gutter downspout runoff away from the house.

NO! It is not okay to use this type of pipe for downspout connections..
All it will do is dump the roof water right next to the foundation. This
happens all too frequently when the contractor installing the pipe doesn't
have a clue as to what he is doing. It needs to be fixed.

| Thx Bob,
I need to be able to point out some standard or trade
organization recommended practice when negotiating with the builder on this.
Otherwise he'll just tell me its standard practice to use perforated and
refuse to swap it out for non-perforated.
I could do it myself, but the point is the house is not even a yr old yet,
so it should be his responsibility to correct, not mine.
So far, however, he's been very slow to address even some agreed upon
cosmetic touch ups in the 30 day (from occupancy) punch list, so getting him
to address this drainage issue may be an uphill dance.

Check with the Plumbing Code (I don't have a copy). Section 1503.4 of
IBC2003 requires roof drainage systems to comply with IPC2003.

Yes normally "soakaways" have to be a minimum distance from the
house/foundations

| What are you complaining about? You got a sprinkler system at no extra
charge.

Baloney! What he got was a whole load of water being dumped right next to
his foundation. Not a very good idea!

| Where can I print out the applicable section of the Plumbing Code, 1504.3?
After Googling it to death, seems this resource is a closely guarded secret
:~(
Perhaps our local library might have the Building Codes and Plumbing Codes
available (?)

That's your best bet. The local library usually has a copy.

The builders of "spec" homes around here use whatever they have lying
around..
The future owner wont know (until its too late). Most dont use weed mesh
either.
The custom home builders here use solid 4" white PVC for the downspout
drains.
They're all routed along the foundation to a common point, then drain into a
gravel sump area away from the house.
The perf black stuff is only used for weep drains at the bottom of
foundation walls
(around here, we are classed as semi arid/desert < 11" rain year so the
soil is very dry).
In wet climes, I'd only use the white PVC with the pre-drilled holes as I've
seen the perf pipe collapsed and blocked with crud (but that was probably
the builders fault for backfilling without gravel and paper in the trench
first)

Isnt it already buried in backfill around the foundation ?

| Yes. I have no practical way of determining the exact routing, but it
appears it may be fairly close in to the foundation.
