Fresh water tank

I have a new xlr 380 amp. When trying to fill the fresh water tank the overflow in the rear let's water out until the tank is only 2/3 full. Anyone know how to stop this so the tank will actually fill completely?

The quick and easy fix is to put a shut off valve on the overflow line. A lot of us have had to do that to completely fill the tanks.

do you have dual tanks?? i have the same problem, only partially filled tanks, when i use water the tanks drain at different speeds and causes my pump to suck air from the first tank emptied. also when filling the overflows seem to spit out water long after i have stopped the supply .

..for the first time the other day it happened to me; had a time getting it to stop, and it might have stopped with or without my fretting. I've read about 2 ways to fix it. One is to slip the overflow hose into a larger pipe with the top of the larger pioe higher than top of the tank. Another way is to replaced the overflow to tank fitting with a tee and attach the overflow to one side and a short hose the other side that extends above the tank. I have not tried either method.

I bet if the over flow hose had a T in line near where it connects the tank it would break the vacuum and stop draining
