I had a leak in my water tank on my 1978 Catalina 25. I was able to repair it by cutting in an inspection port on top of the tank which enabled me to reach in and replace the exit fitting from the tank. Problem solved, See photos.

Harold,

Nice work. My tank never leaked but I got tired of removing it and cleaning it out every year, so I removed it altogether. I hinged the seat shelf and now use the space for much needed storage. I found that, even for extended cruises of a week or more, I only needed about five gallons of water on board, so I don't miss the tank at all. I've kept the tank in case - God forbid, I ever have to sell the boat.

Is it a big deal to get the tank out? Hoe does one do this. Even if I cleaned the tank every other day, the First Mate would never use the water anyway. We bring water on board for little weekend runs anyway...

James,

If you have the traditonal model with the batteries amidships behind the companion steps it's a snap. Just remove the hoses unscrew the inlet outlet to the head sink, and lift it out. I bought small stainless hinges from the local ACE store for the lid. Looking at harolds setup it might be a tad more difficult, and may involve rmoving the small bulkhead inside the compartment.

It will be well worth the effort if you decide to do it though.

I have a fin keel with dinnet, This post made me wonder what my set up was for the water tank, so I pulled it apart, 4 screws...and that was it. this is what it looks like. I am thankful that its built the way it is, makes using the space for water or storage that much better....

I too have a 78 Catlina with that same tank configeration. How did you determine where your leak was?
I was about ready to buy a new tank and go through what would be need to take the old one out and put new one in...but your method maybe what is in order and would sure beat a new tank....providing this is where the leak is.

My surveyor suggested injecting some foam around the water tank to stabilize it in chopy seas--to prevent leaks from developing... Did I do that? Well.......

Bear, my batteries are behind my steps and I tossed my water tank, put piano hinges on both those seat sections, carpeted the hull and now have scads of storage there.

Marshal,

Finding your leak should not be a problem. There is only three possible places it could occur - the inlet from the deck fill, the outlet to the head sink, or the outlet to the galley sink. The tank is so loosely installed that any movemment at all could cause the seal around these points to open.

Personnaly the way Catalina installed those tanks, I believe that in a severe knock down, a full tank might dislodge and cause some major damage to the boat or anyone unfortunate to caught below.

Like Frank, I took mine out and use it for much needed storage.Try it. You'll be glad you did.

I saw the leak when I filled the tank. Fixing it was a problem until I cut that inspection porr in the top. The tank must be supported all around with foam blocks. I do some heavy weather sailing and a full tank could move and cause the exit fitting to break again.

Harold's setup looks just like mine was. The forward and aft bulkheads are tabbed in. There is no way to get that tank out without cuttin out those bulkheads.
Also, there is no support under the tank. It just sits on two corners and kinda leans agains the front of the settee. My tank was twisted all out of shape. Can't be good for the tank. Might cause a crack and leak.
