black water tank

[dereks57]

does anyone know if there are fittings you can drill into the existing blackwater tank so i can move the location of the toilet? i have demo out the whole bathroom in my 68 international and would like to just move the toilet to allow for more room for a shower. also i would have to plug the old hole as well.

Do you know what material the tank is made of? There are clean out/inspection covers made for all sorts of tanks. Some tanks can be welded, others can be glued.

it is plastic

Might be an opportunity to look around and see if there is a larger tank you could put in under there. The Airstreams before 1974 didn't have a grey tank either, for that matter.

If you are going to get that radical, why not bring it up to date as far as the tanks go?

i removed the old tank, it is alot smaller than i thought it would be. there just isnt any room really for a grey water tank.

A 1968 Airstream 30 foot has a holding tank that's almost 4 feet wide.

Fiberglass replacments are available.

Your 45 year old tank will take very little activity before it cracks again and again.

West System makes an epoxy for plastic. It is called G-Flex. It might work to attach a new fitting and to glue down a patch over the old hole. I replaced the old black tank in my 68 Trade Wind with a new fiberglass one from Inland. My old one was too bad to try and fix. I went with OEM style so as not to have to reroute any of the waste lines. It comes with no holes in the top so you can put the flange anywhere you want. Just mark it, drill it and epoxy the new flange adaptor that is included to the tank. Was not cheap, but it saved a lot of time compared to trying to get a generic tank to fit and work with my existing drain lines and vent.
