Hey i recently got a WC system for christmas. Install went fine and runs perfectly, however i've noticed that my water level is dropping somewhat fast. when i first installed it i filled it up to the top. I hadnt noticed any difference until i moved back to school which involved moving my computer obviously, and this dropped the water level down to about 75% full. its been 2 weeks now and its continued to drop to about 40% now. I haven't seen any leaks or had any problems yet, so i'm a little confused about where this water is going. I heard that water evaporates, which is why you need to refill your system every 4-6 months, but i havent had this system for a month yet and im down to 40%. is there something abnormal about that or does it just depend on the set up?
