Winterizing non-pressurized freshwater tanks
I'm in the Baltimore, MD area and have a '75 Newport 28 with a freshwater tank that is not pressurized. The faucets and toilet have a pump handle on them to draw water from the tank. The faucet in the galley is broken, and doesn't draw water any more, though the water is right there in the line just below the faucet. The faucet and toilet in the head are OK.
In my case, would it be better to just disconnect the lines from the faucets and the toilet, and use a shop-vac to blow the water completely out of the system and drain it out via the bilge pump? Then I could leave the system completely empty for the winter, and shock it with bleach and refill in the spring.
Any and all suggestions are welcome.
