Your water hook-up is probably after market
and it should connect to your water system between the pressure water pump and the faucet(s). If it is plumbed into the low pressure side of your water system (your water tanks or the suction side of your potable water pump), you run a serious risk of turning your boat into a bath tub.If you haven't used it, I would carefully examine the hoses on the boat side of the water inlet and on your entire pressure water system before you use it. If any of these pressure lines fail, it can have catastrophic consequences.Having said that, having city water on your boat is much more convenient than filling your water tanks at frequent intervals. Just remember to turn off the water whenever you are not on your boat)or better yet, only turn it on when you think you will be needing it.SteveAlchemist C-320
