1: what are shark bites ?
2: what is purpose of the back flow lines for the black tank , and are they necessary ?
3: I installed a check valve on the line used for flushing the black tank
Thank you for your responses

Shark bites are push on fittings for Pex and various other pipe and tubing.
The back flow preventer stops black tank waste from being introduced into the water supply. Very unlikely, but just a precaution.
A check valve will serve the same purpose as above if installed correctly. Is it a check valve or backflow preventer.
