If it isn't leaking keep her going. As long as it is kept dry and was originally of sound design (which it probably was if it is still holding together) it should last a few more years at least. It will cost a whole lot of beer money to replace it. If you do any work on it don't use any brass or bronze fittings. Get monel or 316 SS pipe fittings ONLY!!! Don't even use other aluminum fittings, they are not the same alloy.
