Next time you flush your tank turn off water to it and let it drain. Leave valve open place bucket under the outlet. Set timer for one minute turn on water to tank and then at one minute turn it off. How much water did you add to the bucket??? I set mine for 10 minutes and I guarantee I am not adding more than 30-40 gallons to a 50 gallon tank.
Set your phone timer for the appropriate time based on gallons.
I've tried timing it but the time varies depending on the available water pressure. It can take as long as 10 minutes at our storage area, but at some parks it will take just over 1 minute to fill.
