Our Momentum has a front 98 gallon main tank with a rear 42 gallon auxiliary tank (according to GD parts listing); there are two fill inlets on the Nautilus system, one marked for each of these two tanks. When attempting to fill the two tanks to advertised capacity of about 140 gallons (not including hot water tank), I am able to fill about 80 gallons before the rear auxiliary tank begins to overflow (this is the same whether I use the main tank fill or the auxiliary tank fill inlet). If I keep filling, eventually the front main tank will also overflow; the rear auxiliary tank does not stop overfilling while the main tank continues to capacity. I understand this is not good for the auxiliary tank as it may cause it to expand too much; it is also time consuming and wastes water. I have tried, on many occasions, to pause filing while the tanks 'equalize'; this does not help. I have contacted GD customer service without them having a solution other than taking it into the shop; they could not explain the questions posed stating engineering does not always keep them informed about these things. As far as I know, this is not a siphoning issue; just a trying to fill the tanks issue.
If anyone can be of help:
Why are there two inlets, one marked Main, the other marked Auxiliary?
What is the solution to fill both tanks close to their advertised capacity without all of this overflowing of water?
Thank you.
