Title: Holding Tanks - what plastic in '76?

Harvey,   Yep, I went the rest of the way and dropped the tanks to find the extent of the damage caused by the leakage.  It was something the previous owner allowed to go on for far too long.  There was a lot of rust -- in some cases braces, etc were rusted completely through.  I repainted after I had wire-brushed, sanded, and even cut out and replaced some of the metal.  The galvanized tank cover had surface rust only, and is reusable.   The rusted framing did not get so bad as to allow the tank cover to sag.  So, there was none of the damage you mentioned done to the tanks or plumbing.  The damaged tank vent fitting I mentioned was where the opening in the floor was off a bit and allowed the fitting to rub against the plywood.  It wore a hole through it there.   Thanks, Jimbo / '76 Sovereign   -----Original Message----- From: Harvey Barlow [mailto:[EMAIL PROTECTED]] [snip]   I hate to be the bearer of bad news but it is very likely that, if you haven't already removed the tank cover and holding tank, a "small repair" to the vent fitting is probably not the extent of the problem you are facing.  In most cases, the rear frame may have sagged, or the angle iron cross-members which support the holding tank have rusted and allowed the tank cover and tank to sag, breaking the vent stub as well as the toilet flange or tank top.  Your holding tank cover may very well be rusted badly, as many older trailers are.   If you haven't already removed the tank cover and tank, I recommend you do so.  Then, once you know the condition of tank cover and tank, list members can offer additional advice.  It is possible to have your existing tank hot air welded if it is not damaged too badly and new tanks can be purchased.  Any tin bender can manufacture a new tank cover, and angle iron supports are simple angle iron cut to the correct length.  If the drain fittings are broken, it can get a little more complicated.
