I wouldn't, then your trusting a check valve to stop a flood in case of a power outage. If your not home, even a 99% closed checkvalve will let the tank drain down to the returns given enough time. That's a lot water on the floor
Honestly I'd be worried about putting bulkheads into the drilled holes on the bottom. That aryclic piece you remove and the reefer pipes, seems the way they designed it was the pipes cracked before you could put that torque on the glass. I'm no engineer but seems that's how they were able to get away with them being so close. With bulkheads, now your relying on the glass to hold if you bump the pipes.
