I was going to use ABS for my bottom drain, but each coupling is another
chance for a leak and I need about 3 joins. Plus the couplings will make the
pipe that much bigger, something I don't need for my tunneling project. But
I was on the Home Depot site and I saw this flexible PVC. It's funny looking
stuff, kinda looks like non kink hose with the ridges filled in. It looks
different than the standard sprinkler PVC I've seen. I checked a couple of
pond sites and one carries the funny looking stuff and the other looks more
like the standard PVC I'm used too. But it's a little hard to tell from the
blurry pictures.

So does the funny stuff exist or is it my imagination? How does it compare
to the standard flexible PVC?

The "funny stuff" is reinforced. It's generally less susceptible to kinking
and crushing than the standard flexible pvc.
When it comes to construction of the bottom drain, the bigger the inside
diameter and more solid the attachment and support structure (especially at
the drain) the better in the long run. That's the last part of the build you
want to deal with doing over. grin

Joe is right about the size and firmness of the drain. How big had
you planned finally to make it? If it is your main bottom drain, you
will want it pretty big. If you put plenty of cement on the joint,
you should have no problem with the pipe joints (easier for me to say
than for you to do). Our drain system is 2" rigid pvc. No problems
for a decade.

Bottom drain will be 3" Tetra, not set in cement I don't think. But I
haven't quite got that far yet.

I set mine in Georgia clay and didn't think it would ever move, but it
did move a bit, but not disastrous. If I did it again I would take
the time and use cement. Even if I had to build a mock up to get it
right.

Did you leave any slack in the liner around the drain?

I'll have to work out the kinks once I actually lay my hands on one. I don't
plan to dig up the existing pond until I'm closer to getting the piping
done. I bored the concrete on the weekend, but did not start the
'tunneling'. Pesky rennovations saved me from the 'good stuff'. :-)

I used 4" schedule 40 PVC with long sweeps for turns and a Tetra drain
on my bottom drain. I doubt I'll dig it up again. If it should plug
I can easily shove a water hose through it, or plumbers tape.

4" is better! Will it ever drain a pond in a HURRY!

Not likely the bottom drain is hooked to a three barrel filter on the
same waterline as the pond, with the pump in the third barrel and the
pump is 1800 gph. It can only pump the barrels half empty except the
last one, so the pump would only remove half the water in the pond.
