Jeff, in all due respect I have some concerns about your post. Now I am not the most earth-friendly woodworker/ homeowner out there, but since this is going into a sump pump, I have concerns with where this bleach is ultimately heading. If it heads into a city sewer or rural leach field I have no issues with it and will give you an apology, but here in Maine a lot of sump pumps just dump the excess water downhill from the home. You might not want to be pumping bleach there however. Just something to think about.
As for attaching the PVC to the concrete walls, plumbers tape would also work and give you plenty of options. Its this soft metal that has a row of holes in it and comes spooled up. Its kind of pricey but is designed to be bent around pipes and ducting, and yet can be nailed anywhere thanks to the holes in it.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
