Hey NOP, I totally agree with this! This is exactly what's going on at Tim's house.
Tim, I would just make sure that you are helping out with the true and pure intention of filling her love tank. If you are unconsciously doing this as a way to oblige her to you, then it is sure to fail. If you have expectations of being rewarded, then she will pick up on that and withhold.
If, however, you are doing this as a way to show your love for her, then keep it up!
