I purchased this BFS-208 100 gpd Reef/Residential RO/DI System a few years back and it has been great. It used to be (when I lived in an apartment) that I could leave the source water on and it would shut off on its own when the pressure tank filled. Now that I'm in a house, however, it will run all day and all night and never stop. I don't have any water leaks and my pressure gauge (came on the unit) reads ~62 psi. Is the psi too high (input psi was ~40-45 in my apartment when it used to shut off)? Do I need to adjust something? I run a sediment filter and carbon block before the RO membrane. The unit is attached to a sink faucet and the ice maker on my refrigerator.

Thanks!
