There is a big difference between normal use of a homes facilities and dumping a tank.
Flushing a toilet will drop 2 gallons of water, A dishwasher will put about 9 gallons into the tank over a thirty minute period,a front loader washer about the same. The only thing that would compare is a full bath and that would still be slower than a tank dump.
The speed of entry is the culprit more than the overall volume. You really do not want wave action in an already fully utilized septic tank. A wave can float the solids over the baffles and into the distribution box.
I am not saying that the OP cannot do what he is proposing,just trying to make him aware of a possible pitfall.
Good point. I wasn't thinking of the "dump" but rather the overall capacity. A macerator would mitigate some of that since it's not physics but mechanical and thus no rush but instead a smaller regulated flow.
