Best rust solution?

Henry, I believe your major buildup is calcium with a rust tint. I don't recall you using distilled water in your system with the additive. Remember where you live is the remains (Salt Lake) of a giant prehistoric inland ocean and your ground water is rife with calcium/lime from all those little shell critters. Try some Limeaway on those pumps. If those deposits in the pump foam up then it is a calcium problem.

I generally try to use either distilled water or softened (decalcified) water. Sometimes on the road, though, when the water blows out I put in whatever is at hand. Usually drinking water from a convenience store (has some minerals in it).

As far as I know, Lime-away is just an acid like vinegar, both of which should dissolve calcium. If I have both rust and calcium it may take both the Evapo-rust and vinegar to do the job. We'll see.
