Holding Tank On A 30T
Until your post I had never heard of a 30T with a flexible holding tank. I believe all 30Ts had a aluminum holding tank under the cockpit port side aft lazarette floor panel (below the batteries). These tanks have been notorious because of deterioration and I suspect a previous owner removed the original and installed your present flexible tank. I agree with the two prior posts that it is a BIG mistake to depend on a flexible tank. I have pictures and instructions describing how I replaced my aluminum tank with a plastic one in the original location on my 30T (1991). I have already sent this material to twenty-one interested 30T owners. If you are interested contact me through the Owner Directory.
