I have a 1986 Ticon-30, with a holding tank
that is built into the hull
below the V-berth. The sides and bottom are fiberglass
and there is a plexiglass (?) lid with that is secured with machine screws and nuts. The lid has two access holes with 6 inch threaded plastic caps. Because of odor
, vent size and other issues I decided to do the nasty job of taking it all apart, cleaning
, upgrading the vent size and putting it all together again. The boat
is in freshwater and I have read Peggy Hall's book.
1) What can I use to clean the inside of the fiberglass
tank and lid? There is a small amount of scale but a lot of odor
2) What should I use as sealer on the (~ 1 inch) flange between the fiberglass tank and plexiglass lid? Would Butyl Tape be suitable? Should I roughen up the surfaces or leave them smooth?
3.) The stainless steel
evacuation tube does not reach the bottom tank. Several inches of water
remain after a pump
out. Is this intended/desirable?
