If you use this method to test; BE SURE to crack the bib valve and immediately shut it off. Check inside at a faucet for water pressure.
If you have water pressure at a tap. you have the correct connection.
If no pressure you have connected to the TurboFlush.
FYI, running full pressure water into the TurboFlush with the black tank drain valve closed can burst the tank. It is a warning in the manual.
