Need to check the 'routing' of the filler hose.
If it sags then water will back up when just pouring water in but can flow when using a hose
An your fresh water tank doesn't have a 'pressure relief valve'.........just a vent line that also needs to be straight, no kinks, no sags and higher than top of tank. Size of vent line will determine how fast you can gravity fill if filler hose doesn't have room to vent escaping air also.
