is the non return valve in the base of a BIORB removeable, inehrited my old mans biorb, i have been cleaning it up, i tried to remove the check valve in the base of the unit and have pretty much massacred it in the process...

i ahve a spare valve to replace it with, but im not etirely sure the one in the base comes out, seems impossibel to budge, have tried oiling it aswell!
