It seems that the water tank in my 2016 Hawk has at least two gallons of water at the bottom that the pump can't reach. Is that normal?
Now that night temperatures have reached freezing where I live, I decided to add a couple of gallons of potable antifreeze to the tank in case there's any water in the bottom.
After I added the two gallons of antifreeze, I turned on the pump and opened the faucet to pull antifreeze through the plumbing. The pump labored and drew a mixture of air and water. That seems to indicate that the pump inlet is just about at the height of the top of the 2 gallons in the tank. Right?
There might have been even more water in the tank before I added the antifreeze. Last weekend, I filled the tank until water ran out of the vent, and then I drained the water through the valve on the bank of the truck. Catching the water in 5 gallon buckets, I was able to measure 18 gallons before the water stopped draining (with the truck on a 10 degree incline to help the draining). If the tank capacity is 20 gallons, then there may have been two gallons already in the tank before adding the antifreeze.
