And besides...you should never just turn on the dock water and immediately fill the tank 'cuz the critters that create funky tank water really thrive in dock supply lines sitting in summer heat. So always let the water run long enough to clear out all that's been sitting in the dock supply line--you'll know because water straight from the main will be a lot cooler-- before filling your tank. You don't have to waste the water....wash the boat, pull out your anchor rode and hose it off...there are plenty of ways to use it.
