What do you have in your back compartment? Anything slowing down the water flow? I found out I had too much filter floss in mine and the pump was emptying the last chamber too fast! I fill a bucket up once a week for my ro top up water I leave it on for 3 hours to fill it and another 3 for my water change. Maybe getting a new Ro unit a 6 stage one built in under the sink!
