@PeterPam posted:Have you tried backing into the tank height setting? You can do this by putting in a measured amount of water with a hose end meter like this one,

Then adjust the tank height to suit. I found it was best to do it at, say, 1/3 full (15 gallons), 1/2 full (22.5 gallons), 2/3 full, and full (45 gallons). If you adjust it at each increment you can zero in on a setting that will be very close. I discovered that you can input fractions of an inch like 7.6" even though the display will round it off to full inches.
Yes I did use a flow meter. … could not zone in on a value that was acceptable for both the bottom 1/3 and top 1/3. Maybe I need to try again. I didn’t know about the fractions.
