19CB. The manual says I have a 27 gallon fresh water tank. I had recently drained it by using the white plastic petcock on the side until nothing else came out. I then refilled it and my flow-meter said I put in 20 gallons before it started to overflow.
So now I'm confused as to what size it may really be (side note: the 2021 models appear to be 23 gallons). Even after being full the indicator inside only shows 94%.
Did I not completely get the tank empty? I tried opening some faucets to maybe burp the system but it would overflow again not long after turning the water back on.
Any thoughts? Our water pump seems to get some air into the system and gets a little loud when putting out water when the meter reads 13% inside so I want to ensure I'm taking as much water on board as I can.
