Are you not concerned with the check valve failing? I didn't use them when I did my plumbing since I had read so much about detritus/sponges/snails/worms getting in and causing the check valve to malfunction. Perhaps check valve technology has changed since I did my research?
I use a transparent true union check valve, so I can easily monitor its condition/performance and maintain it as necessary. I also run an Fluval SP4 wide open, so it would take one determined critter to get down to the check valve. Basic setup before some tuning/modifications.
