Look under the port side settee. You will see your water system valves that are Marked 1-2-3. In the manual you will see which tank is labelled front/rear. I recommend you only use one tank preferably Forward(weight distribution) unless you need more capacity for trip. I usually put some water purifier or vinegar in tank not being used to keep critters out of water.I am a new owner of a 2012 B37. It has 2 water tanks. One is 3/4 full and the other is 1/2 full. So, they must not be connected! where can I find a valve to use one or the other? Thanks in advance.
Page 72 of my owners manual. You're looking for white knobs about 1" round on a manifold.Thanks for the input. I have read the info several times, The water section must be missing. I have seen the water system under the port seats but was looking for lever valves. I will look in more detail on my next visit to the boat.
