draindrainage
I want to add a channel drain at the front of my lean-to in order to direct rainwater from the lean-to's drainpipe into the existing house drainpipe. I understand that this is not a typical usage situation for a channel drain, but I can't see why this wouldn't work?
This is the channel drain I am thinking of buying:
And this is how I am thinking of connecting the two drains:
I have never come across flanges that weren't compatible, and haven't seen manufacturers specify TPI on their kits or replacement parts. There are plenty of oddball pieces here and there but upon coming across those (on rare occasions), I'd be replacing the entire assembly.
There is really no way to know the TPI without removing the flange, but chances are you will be dealing with coarse threads.
I had nearly the same problem and a single french drain made the problem go away. It is important (and probably worth reinstalling if not done) to have:
The french drain also should start prior to the onset of the wet area.
