Fresh water tank drain

Has anyone ever installed a water drain on the fresh water tank? We have our Humter 28.5 and I would like to be able to dump the water tank without running the pump at the end of a sailing weekend (or week) before we leave the boat.

Was thinking of a above waterline through hull and a ball valve. Then at the end of a weekend, be able to just open the valve and dump the water. (Then close it again.).

Any thoughts?

If your tank sits above the waterline, then you can just use a hose to siphon the water out of the tank. Otherwise, an eductor will let you pump out the tank using only water pressure. Eliminates another thru hull.

I have a tee on the 40-gallon tank outflow. You can put any fitting on one side that you can hook a pump to- either one in an electric drill, or why not just pump it out through the ships water system?

Why dump the water?
If you are afraid of it, add some purifying drops.

I keep a bottle in my survival kit.
BTW we very seldom drink our boat water. Kentucky Bourbon and branch water works well too.;)

If it smells add this...
