Painting Inside A Water Tank

If it was just used for detergent, pressure wash it. Normal detergent isn't the most toxic of substances and you'd get more of a detergent dose from a glass you didn't rinse properly.

I'd be much more worried about leftover compounds from the epoxy. (WEST don't recommend theirs for lining vessels used to store drinking water).

Bob
If you can get the tank clean enough that the coating will adhere to the sides, I can't see any valid reason to apply any coating

But if you insist
Don't use epoxy — the fumes confined inside the tank will probably kill you
I'd be similarly concerned with oils based paints

look at one of the latex waterproofing paints

It was hospital detergent. Don't know what.

I was thinking wests epoxy as its a lot cheaper than bitumeous,
thanks for that MS, looks like its hydroseal for the job.
