if it's not repelling the water, and it is absorbing all is fine. sounds like maybe you are trying to water too soon or the substrate is hydrophobic. if the pot is heavy and you can tellit is absorbing water, it is not hydrophobic.
seems like you are choosing how much water to give instead of allowing the soil to dictate. It may have a different water-holding capacity than what you used before, so it will take a different volume to get the job done.
1 - Water until you get a little runoff -- in soil you minimize this to avoid leaching out your amended nutes that you paid for.
2 - Wait until top layer dries, and re-irrigate.
if deviating from that, you are doing it wrong and that is the problem.
now, if you have hydrophobic soil, the water will run off without absorbing... this is a very poorly made potting soil, if true, lol. They didn't add a wetting agent. If this is the case, look up using yucca extract or some other wetting agent/surfactant to condition your soil.
