The 1/4" npt holes are if you want to use the Stenner fittings that are included in the Stenner parts bag, or for threading into the Pump trap drain plug. Its the same thread as for the drain plug.
However, you're better off using the injector fittings provided by AutoPilot for all holes drilled.
It's a 3/8" drill bit needed for the injector fitting.
The check valve for the acid line will prevent any back flow or pressurized water going back into the tank.
It can be below water level and exposed to the environment.
