We have a 2021 Keystone Avalanche 312RS... I am connected up to city water and set for normal flow at the water service station (valve can turn to fresh fill also). Fresh tank fills up on this normal flow setting! (not supposed to do this unless valve turned to “fill” position.).. Water eventually starts overflowing from the fresh water tank exterior drain overflow outlet after fresh tank is full. (in gallons per couple minutes so I have to shut off city water supply !) Tried draining fresh tank and running city water several times on the normal flow setting and once the fresh tank is filled up (which not supposed to do on the normal setting) again the overflow starts pouring out again. Basically a we are having to fill fresh tank, turn off main water and run our rig on pump (with park water off) until fresh runs out. Any ideas where to start? I’m pretty handy just wondering if it’s at the normal flow/fill valve in the water compartment or a check valve in the fresh water tank area? Where to start diagnosis?
