How do you fix a CDS recovery tank?

[ruff]

My 11 years old CDS aluminum recovery tank is showing signs of damage.It leaked by the welding of the sleeve of the dumping pipe. Put a ring and epoxy around it and that solved it (don't know for how long. Now it is showing signs of damage (maybe 3'x3") by the flat wall around the dumping pipe (front).

Is there a practical solution (say a few years) that does not involve a tank refurbish or a new tank?

The cost of refurbish and or new one that I was quoted ($4,000 or $6,000.) is so high that it would make more sense to buy a new machine.

I have been quite succcessful using fiberglass mat impregnated with polyester resin - 2 coats. DA sand first, and prep-clean area before glassing.

I grew up with my dad involved in building fiberglass boats. My dad was also a civilian pattern maker working at WPAFB (Wright Patterson Air Force Base).

Aluminum recovery tank used daily for 28 years, back in service thanks to fiberglass.

Ofer;

At that age and with multiple areas of corrosion . . .

I would look for a new tank.

We have a quality 90 Gallon SS recovery tank for $1099:

Bob's solution fits your request.

Not just any tank will fit your configuration.

That's what I wondered. I have a Butler tank you could have for a song....well with that voice maybe a a song and a dance!


I do have one I can send you pictures and measurements if you think it would work.

I had a tank from a hydramaster cds 2000 model that was severely corroded. I researched and bought a product called coal tar epoxy. First I cleaned and pressure washed the tank, then I sprayed oven cleaner on it to etch the surface. FInally I used a small roller and put 3 coats of the coal tar epoxy on it. Lasted 3 years. One spot in the tank I could actually see the black epoxy through a hole that was about 1/16 inch. As a side benefit cleaning the tank was much easier with the epoxy. If I bought another cds it would be the first or second thing I did to it before putting it in service

Thank you Richard, that's a sweet offer. Not sure exactly how I can find out if it will work or not.I'll ask around. Or maybe someone here in the know can chip in.

I am a whiz with Hebrew songs, practically an IICRC certified nightingale.

I fixed a hole about the size of a BB in my waste tank with tin foil and super glue. Still holding, right by the drain valve too.

The key to any successful epoxy repair is to properly prep the surrounding surface.

Don't skimp on the prep work.

I had to have 2 patches welded on my fresh water tank. Cost is minimal. Hopefully you wont have to pull it out.
