How do you switch water tanks in a Catalina 30 1985 tall rig?
Where do I find the mechanism to switch from one tank to another?

In my MK II, the water tanks each have a shut off valve in them. They are located at the area of the water tank where the hose exits the tank. I usually just leave both of mine open as it seems to boost water pressure slightly.
water tanks
I have a 1984 C-30 and am not sure if the water system is the same. My system mainly uses the bow tank first. When empty, there is a shut off valve just inside of the access hatch at floor level in the bow. This has to be closed with the bow tank drained or the system will suck air and loose the prime. The second (starboard) tank will now supply the system. There is a check valve under the fuel tank hatch in the stern where the bow and stern tank hoses join. (I never really figured out what this valve does or why it is there.........but I'm sure there must be a good reason!) You could close the bow valve at any time to use the starboard tank.
It would be wise to keep the tanks separated and use one at a time. "Cuz if you do't you'll never know when you're gonna run out of water. Using one at a time and keeping them both full allows you to empty one and still have a backup with time for a refill. This is Simple Boat Management 101. With a pressure water system having both open makes absolutely no difference in system pressure when the pump is running. Engineer-speaking.
