Has anyone else used PVC sewer pipe for rain gutter downspouts?
The outlet on the rain gutters on my barn were larger than the average
home rain gutters. (I believe 3 inch). The local lumber yard said it
would be a special order, and the price was outrageous. So, for about
$10 I bought some 4" pvc sewer pipe and a few elbows and 45's and used
metal straps to secure it to the barn. It's been on there for 1 1/2
years and has worked well. Never clogged, never any problems, and
looks fine too.
The only problem is that I glued it, and now I am adding on to the
barn and need to extend and re-fit it. Of course I cant take the
glued joints apart. Yeah, I know to cut it and couplers, etc.
However, I am just going to save it the way it is (because I can use
it on another part of the barn), and make a new one with new
However, I have a question. Rather than glue the new one, I am
wondering if it would work to just drill holes in the fittings and
install sheet metal screws. (of course all joints "bells" must face
upward or be glued if they do face downward).
Using screws instead of glue allows me to make changes if I want.
Particularly the bottom elbow, since I may want to turn it in the
future to change the direction of the ground level extension pipe
Has anyone tried this?
PS I did not screw the top of the downspout to the steel gutter drop,
I just pushed it tightly against the gutter and securely strap it to
the wall. I never had any problems with this.
