glue hdpe to pvc?
I ran all my exterior downspout drains a few years back with the thin walled PVC 4". I am now running the pipe another 100 feet to dump out into the woods. Now I see all the home centers carry is the dual walled 4" pipe (HDPE outer, black inside)... with slip fittings. I'd really like glued joints to make sure that I am not leaking water all across the yard, but is there any glue that I can use in the slip joints to make sure it is water tight... and also does not slip out?
