Had some fresh water in the bilge awhile ago and was unsure whether it was from snow or a leaking water tank. So, today I went to the boat to fill the empty tank to help isolate the issue. Filled the tank and did an inspection and no water was leaking from beneath the tank. Whew! The bilge pump works fine, so in a couple of weeks when I check the boat again, I'll see whether there is no more fresh water in the bilge. If so, well...
