the problem. it indicates that y-valve is not functioning. Is it possible?
Certainly there could be a problem in the y-valve. Could be something from the fridge came down the hose and is stuck in the valve or some other problem with the valve itself.
So just do the same test but one step further down the line. Pull the hose that goes from the y-valve to the pump where it connects to the pump. If the y-valve is turned to the ocean side then water should come out. You can just hold your thumb over the hose to stop that. Now switch the y-valve to the freeze and blow again. if you can blow into the hose connected to the freezer drain but you cannot blow through the y-valve then there is a problem with the valve or a clog in the valve.
If you can blow all the way from the hose pump, through the y-valve and through the hose to the freezer but still cannot pump the water from the freezer then there must be a problem with the pump or something clogging the hose somewhere.
