Fresh water tanks have Overflows & Vents
Vents can be small diameter and if vent line sags water can get trapped in low end and block all venting
Overflows come out top and extend below enclosed underbelly
Should NOT have shutoff valve on it...should be open pipe typically 1/2"
Even the KZ Manual states...."Each storage tank has an over flow line."
Several Garden Hose Meters available on Amazon for $16-$30
Rainwave, Orbit, P3 ---pick one
I didnt see that in my maual but it does say do not overfill the tank as it could burst. It is not designed to hold pressure. That leads me to the no overflow. But you are correct it says there is an overflow. I will have to look for it. As filling untill it overflows is ideal.
