Pink antifreeze turned purple

[Kyte]

Newbie here,

I put good old Walmart antifreeze (Super Tech) in the camper.
It went in pink, but turned a light purplish color at the faucets.
Checked the clear water lines and all looked light purple.

Its the same stuff I used last year with no problem. It went
in pink and came out pink. I checked the ingredients and they
are the same as last years right down to the ingredients numbers.

Any ideas why?

Pink to purple........hmm you're saying it's the same brand of antifreeze but the colour differs. Could be one of 2 different possibilities as I'm seeing it:

1. If it's a different batch (you didn't say) it could be the manufacturer is using a different chemical composition. Maybe an OAT as opposed to a HOAT composition now.

2nd possibility is various chemicals/minerals in the water leached into the pipes (D/K if your piping system is metal or "plastic") and is now noticeable in the antifreeze upon draining.

All I can think of.

most pink stuff will freeze but it does not expand when it freezes like water does dave

Didn't blow out the water lines. Didn't last year either.

I'm not sure exactly how to do it.

Like I said, I'm a newbie.

I will put some in the freezer and see what happens.

Thanks

Kyte. Did you blow out your water lines b/4 you put the new antifreeze in? If not, it will be mixed with the water in the lines and HW tank. Put some of the pink/purple liquid out of your faucet in a cup, and place in your freezer. It might turn into slush, which is OK, but if it freezes solid, it might be too weak. Eddie Elk.
