I was very surprised the other day while sanitizing the system I found that there was still water in the fresh water filler tube,,, even after the system had been drained ??? Guess I will be blowing that out next fall !!!
In the past I have found water in the filter canister after I have blown the system out using the City water connection,,, and even after removing canister and drying it !!!
Maybe now I know where that water came from ???
But how could that water get past the pump,,, into the canister ???
I figured it had to have drained back from some where ???
Last year it cost me a canister & the unit it screws to,,, + about 3 hours,,, that was after a 2 hour trip to get new unit !!!
