Question on waterproof plywood

I'm in the process of replacing the plywood that was under my fresh water tank. Due to a leak the original plywood (half inch with a thin layer of metal on each side) completely rotted. I spoke to Lowe's and they said they have "orange" plywood that's the equivalent to marine grade. I was thinking of going this way but thought I'd check if anyone had any other recommendations.

Thanks much,

Pressure treated ply is also available and will resist water and rot.

Bill, go to your local lumberyard and see what they have, a nice piece of 1/2'' ACQ should work out fine for you, G

First, fix the leak! Whatever you put down there will be destroyed in time if there is a constant source of water. (Don't ask me how I know this.)
If you can get the holding bays dry then you can use any plywood and it will be fine. You should seal the wood with a good deck or garage floor paint if you don't use a laminate or similar thin layer of metal. Be sure that you seal and insulate the underside as well to prevent the road moisture from taking over where the interior leak left off.

You might want to check out a product boaters use. I believe it's called "Wonder Board". You can cut it, drill it, do anything with it that you can do with wood. But.... it will never rot, because it is made of what looks like plastic (white). It comes in 4' X 8' sheets. However, it is not cheap. the last time I checked, it was just over $200 a sheet. But you can buy smaller sheets than 4' X 8'. It works great!

Thanks for all the recommendations. I appreciate the responses.

Bill A. I'm with you 100%. I have (had) 2 leaks. One at the pump and, unfortunately, one on the bottom of the tank. I'm planning on trying to find someone local to take care of the tank leak (Chicagoland area). Any suggestions on that would be appreciated as well.

Anyone patched a fresh water tank themselves?

Thanks again to everyone. Great forum.
