Ok so if I do the antifreeze wintwrize, after draining everything and pumping antifreeze thru they say then dump black and grey tanks last..
Should I dump half a gallon of antifreeze in each black and grey tank ??
Also I just leave the waterheater empty and the bypass lever in the bypass position ?
I always do. those tanks are never really empty. same with the WH bypass. and I slowly pour a small amount in each drain for the p-trap along with a moderate amount in the john to keep the blade seal moist.
