Love the threads.
I returned after Christmas to find us frozen in place. Heating worked (which was fotunate) but as we "winterised" the boat we drained the water tank.
Tried to fill up from tap, reeled 50 mtr of hose out to get a trickle of water out the other end, so that means its frozen too!
20 minutes in a hot shower made the water defrost and a quick sprint to connect it up and test it, made it work.
Wish I had my camera, 50 mtrs of hose in a shower is a picture, just to get water to your boat.
