HOW TO SEAL TINY LEAK IN 1993 WL BLACK WATER TANK?

[Jack and Liz Pearce]

Howdy, Forumites.
We discovered a tiny leak in our coach's black water tank. :-& :-& I have
created a photo album in the Photos section entitled Pearce 1993 BWT with photos
of the location of the leak. We DON'T KNOW the composition of the tank so are
not sure as to what material to use to seal this leak. Jack has used some RTV
to try to seal the leak. He will check it daily to see if the RTV has fixed the
problem. It looks as though the tank has been repaired before in this same area
but we don't know for sure. Suggestions, ideas and recommendations would be
much appreciated in helping us solve this problem. We feel that we should be
able to go 5-7 days before having to dump the BWT. :-?

Thanks,
Liz

Your use of RTV may hold up...if it does, your done! But if you
have further problems, i can recommend a product i have found often
at hardware & marine stores...Starbright/West Marine Epoxy Putty
Stick. Comes in a tube, you cut off what you need, knead it for a
minute, stick it on, mould it, and in a while, it hardens like
stone! As such, it is not a good gasket material, but a good plug
or used to fill. I have used it for my a black tank leak (just a
slow drip near a fitting, perhaps a rock hit) and it has held up
great for over a year. I just cleaned the area up with sandpaper
and used it. I always keep some handy, it stores well.

I always attempt to fix a problem on my coach the best way possible
so it is restored to its original or better condition. On my 1982
FC35 the black and grey water tanks are fiberglass. I had a small
leak at the output of the black water tank and since the connections
were over 20 years old, decided to cut them off and start from
scratch again. On my tanks the outputs were heavy PVC female screw
connectors that were still clean and tight so I just replaced
everything from there to the outlet of the ABS pipe and added
electrical dump valves.

On your 1993 Jack I would call Bennie at BB and ask him what your
tanks are made of. If they are fiberglass then you have a relatively
easy fix. If they are some form of plastic then that is easily fixed
also. There are plastic welding kits that you can buy that will make
a weld every bit as good as the original. The plastic rods to weld
with come in a variety of types and are easily purchased. I happen to
have a rather expensive Leister triac welder that I was fortunate to
have purchased new at a flea market.

If you do have some type of plastic tanks this might help

OK, thanks for the reply. I will definitely have to find out what the tank is
made of.
