There is a couple things that might be going on there maybe a water saving setting turn on for the unit. This requires moving the plan a check a few things. Are you comfortable with working on the unit. Also the second thing is if the demand is set correctly then the have demand pumps you can add to the system to help with the issue which is what Richmond/Rheem recommends.

Yeah... I'm comfortable with dip and PLC's. I went throught the options for settings in the manual but nothing seemed likely to correct the issue. This unit is set up on a well and has a pressure tank. I have not installed any jockey pumps to recirc as yet but could if that;s the answer.I wont be able to get back to it until Saturday.Steve
