Unfortunately the tank was drilled with the hole in bottom for the return when we got it. Is there anything else a guy can do other than a check valve? Also a quick question about return pumps.... our quietone 6000 constantly hums pretty loudly. Its more like a resonant frequency hum but after a while it really grates on your nerves. Is this normal? Can this be avoided with say an external type pump... ie reeflo snapper gold or one similar?
