Just a note to you using your new unit. You should let it run for 24 hrs before using any of its water.Throw out the first 24 hr patch of water. My wife works for a company that makes RO filters and she said you should for sure do this flush out run. It usually says on the unit to run it for 10hr, but wife says at least 24. The reason being there is residual production chemicals in the filters so they need to be flushed.
